Chapter 65. Spring WebService
Since Camel 2.6
Both producer and consumer are supported
The Spring WS component allows you to integrate with Spring Web Services. It offers both, client-side support for accessing web services, and server-side support for creating your own contract-first web services.
Maven users must add the following dependency to their pom.xml
for this component:
<dependency> <groupId>org.apache.camel.springboot</groupId> <artifactId>camel-spring-ws-starter</artifactId> </dependency>
Use the BOM to get the version.
<dependencyManagement> <dependencies> <dependency> <groupId>com.redhat.camel.springboot.platform</groupId> <artifactId>camel-spring-boot-bom</artifactId> <version>${camel-spring-boot-version}</version> <type>pom</type> <scope>import</scope> </dependency> </dependencies> </dependencyManagement>
65.1. URI format
The URI scheme for this component is as follows
spring-ws:[mapping-type:]address[?options]
To expose a web service mapping-type needs to be set to any of the following:
Mapping type | Description |
---|---|
| Offers the option to map web service requests based on the qualified name of the root element contained in the message. |
| Used to map web service requests based on the SOAP action specified in the header of the message. |
| In order to map web service requests that target a specific URI. |
|
Used to map web service requests based on the evaluation of an XPath |
|
Allows you to reference an |
As a consumer the address should contain a value relevant to the specified mapping-type (e.g. a SOAP action, XPath expression). As a producer the address should be set to the URI of the web service your calling upon.
65.2. Configuring Options
Camel components are configured on two levels:
- Component level
- Endpoint level
65.2.1. Component Level Options
The component level is the highest level. The configurations you define at this level are inherited by all the endpoints. For example, a component can have security settings, credentials for authentication, urls for network connection, and so on.
Since components typically have pre-configured defaults for the most common cases, you may need to only configure a few component options, or maybe none at all.
You can configure components with Component DSL in a configuration file (application.properties|yaml), or directly with Java code.
65.2.2. Endpoint Level Options
At the Endpoint level you have many options, which you can use to configure what you want the endpoint to do. The options are categorized according to whether the endpoint is used as a consumer (from) or as a producer (to) or used for both.
You can configure endpoints directly in the endpoint URI as path
and query
parameters. You can also use Endpoint DSL and DataFormat DSL as type safe ways of configuring endpoints and data formats in Java.
When configuring options, use Property Placeholders for urls, port numbers, sensitive information, and other settings.
Placeholders allows you to externalize the configuration from your code, giving you more flexible and reusable code.
65.3. Component Options
The Spring WebService component supports 4 options, which are listed below.
Name | Description | Default | Type |
---|---|---|---|
bridgeErrorHandler (consumer) | Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored. | false | boolean |
lazyStartProducer (producer) | Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel’s routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing. | false | boolean |
autowiredEnabled (advanced) | Whether autowiring is enabled. This is used for automatic autowiring options (the option must be marked as autowired) by looking up in the registry to find if there is a single instance of matching type, which then gets configured on the component. This can be used for automatic configuring JDBC data sources, JMS connection factories, AWS Clients, etc. | true | boolean |
useGlobalSslContextParameters (security) | Enable usage of global SSL context parameters. | false | boolean |
65.4. Endpoint Options
The Spring WebService endpoint is configured using URI syntax:
spring-ws:type:lookupKey:webServiceEndpointUri
Following are the path and query parameters:
65.4.1. Path Parameters (4 parameters)
Name | Description | Default | Type |
---|---|---|---|
type (consumer) | Endpoint mapping type if endpoint mapping is used. rootqname - Offers the option to map web service requests based on the qualified name of the root element contained in the message. soapaction - Used to map web service requests based on the SOAP action specified in the header of the message. uri - In order to map web service requests that target a specific URI. xpathresult - Used to map web service requests based on the evaluation of an XPath expression against the incoming message. The result of the evaluation should match the XPath result specified in the endpoint URI. beanname - Allows you to reference an org.apache.camel.component.spring.ws.bean.CamelEndpointDispatcher object in order to integrate with existing (legacy) endpoint mappings like PayloadRootQNameEndpointMapping, SoapActionEndpointMapping, etc. Enum values:
| EndpointMappingType | |
lookupKey (consumer) | Endpoint mapping key if endpoint mapping is used. | String | |
webServiceEndpointUri (producer) | The default Web Service endpoint uri to use for the producer. | String | |
expression (consumer) | The XPath expression to use when option type=xpathresult. Then this option is required to be configured. | String |
65.4.2. Query Parameters (21 parameters)
Name | Description | Default | Type |
---|---|---|---|
messageFilter (common) | Option to provide a custom MessageFilter. For example when you want to process your headers or attachments by your own. | MessageFilter | |
messageIdStrategy (common) | Option to provide a custom MessageIdStrategy to control generation of WS-Addressing unique message ids. | MessageIdStrategy | |
endpointDispatcher (consumer) | Spring org.springframework.ws.server.endpoint.MessageEndpoint for dispatching messages received by Spring-WS to a Camel endpoint, to integrate with existing (legacy) endpoint mappings like PayloadRootQNameEndpointMapping, SoapActionEndpointMapping, etc. | CamelEndpointDispatcher | |
endpointMapping (consumer) | Reference to an instance of org.apache.camel.component.spring.ws.bean.CamelEndpointMapping in the Registry/ApplicationContext. Only one bean is required in the registry to serve all Camel/Spring-WS endpoints. This bean is auto-discovered by the MessageDispatcher and used to map requests to Camel endpoints based on characteristics specified on the endpoint (like root QName, SOAP action, etc). | CamelSpringWSEndpointMapping | |
bridgeErrorHandler (consumer (advanced)) | Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored. | false | boolean |
exceptionHandler (consumer (advanced)) | To let the consumer use a custom ExceptionHandler. Notice if the option bridgeErrorHandler is enabled then this option is not in use. By default the consumer will deal with exceptions, that will be logged at WARN or ERROR level and ignored. | ExceptionHandler | |
exchangePattern (consumer (advanced)) | Sets the exchange pattern when the consumer creates an exchange. Enum values:
| ExchangePattern | |
allowResponseAttachmentOverride (producer) | Option to override soap response attachments in in/out exchange with attachments from the actual service layer. If the invoked service appends or rewrites the soap attachments this option when set to true, allows the modified soap attachments to be overwritten in in/out message attachments. | false | boolean |
allowResponseHeaderOverride (producer) | Option to override soap response header in in/out exchange with header info from the actual service layer. If the invoked service appends or rewrites the soap header this option when set to true, allows the modified soap header to be overwritten in in/out message headers. | false | boolean |
faultAction (producer) | Signifies the value for the faultAction response WS-Addressing Fault Action header that is provided by the method. See org.springframework.ws.soap.addressing.server.annotation.Action annotation for more details. | URI | |
faultTo (producer) | Signifies the value for the faultAction response WS-Addressing FaultTo header that is provided by the method. See org.springframework.ws.soap.addressing.server.annotation.Action annotation for more details. | URI | |
messageFactory (producer) | Option to provide a custom WebServiceMessageFactory. For example when you want Apache Axiom to handle web service messages instead of SAAJ. | WebServiceMessageFactory | |
messageSender (producer) | Option to provide a custom WebServiceMessageSender. For example to perform authentication or use alternative transports. | WebServiceMessageSender | |
outputAction (producer) | Signifies the value for the response WS-Addressing Action header that is provided by the method. See org.springframework.ws.soap.addressing.server.annotation.Action annotation for more details. | URI | |
replyTo (producer) | Signifies the value for the replyTo response WS-Addressing ReplyTo header that is provided by the method. See org.springframework.ws.soap.addressing.server.annotation.Action annotation for more details. | URI | |
soapAction (producer) | SOAP action to include inside a SOAP request when accessing remote web services. | String | |
timeout (producer) | Sets the socket read timeout (in milliseconds) while invoking a webservice using the producer, see URLConnection.setReadTimeout() and CommonsHttpMessageSender.setReadTimeout(). This option works when using the built-in message sender implementations: CommonsHttpMessageSender and HttpUrlConnectionMessageSender. One of these implementations will be used by default for HTTP based services unless you customize the Spring WS configuration options supplied to the component. If you are using a non-standard sender, it is assumed that you will handle your own timeout configuration. The built-in message sender HttpComponentsMessageSender is considered instead of CommonsHttpMessageSender which has been deprecated, see HttpComponentsMessageSender.setReadTimeout(). | int | |
webServiceTemplate (producer) | Option to provide a custom WebServiceTemplate. This allows for full control over client-side web services handling; like adding a custom interceptor or specifying a fault resolver, message sender or message factory. | WebServiceTemplate | |
wsAddressingAction (producer) | WS-Addressing 1.0 action header to include when accessing web services. The To header is set to the address of the web service as specified in the endpoint URI (default Spring-WS behavior). | URI | |
lazyStartProducer (producer (advanced)) | Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel’s routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing. | false | boolean |
sslContextParameters (security) | To configure security using SSLContextParameters. | SSLContextParameters |
65.5. Message Headers
The Spring WebService component supports 7 message headers that are listed below:
Name | Description | Default | Type |
---|---|---|---|
CamelSpringWebserviceEndpointUri (producer)
Constant: | The endpoint URI. | String | |
CamelSpringWebserviceSoapAction (producer)
Constant: | SOAP action to include inside a SOAP request when accessing remote web services. | String | |
CamelSpringWebserviceSoapHeader (producer)
Constant: | The soap header source. | Source | |
CamelSpringWebserviceAddressingAction (producer)
Constant: | WS-Addressing 1.0 action header to include when accessing web services. The To header is set to the address of the web service as specified in the endpoint URI (default Spring-WS behavior). | URI | |
CamelSpringWebserviceAddressingFaultTo (producer)
Constant: | Signifies the value for the faultAction response WS-Addressing FaultTo header that is provided by the method. See org.springframework.ws.soap.addressing.server.annotation.Action annotation for more details. | URI | |
CamelSpringWebserviceAddressingReplyTo (producer)
Constant: | Signifies the value for the replyTo response WS-Addressing ReplyTo header that is provided by the method. See org.springframework.ws.soap.addressing.server.annotation.Action annotation for more details. | URI | |
breadcrumbId (consumer)
Constant: | The breadcrumb id. | String |
65.6. Accessing web services
To call a web service at http://foo.com/bar
simply define a route:
from("direct:example").to("spring-ws:http://foo.com/bar")
and send a message:
template.requestBody("direct:example", "<foobar xmlns=\"http://foo.com\"><msg>test message</msg></foobar>");
If you are calling a SOAP service, you must not include SOAP tags. Spring-WS performs the XML-to-SOAP marshaling.
65.7. Sending SOAP and WS-Addressing action headers
When a remote web service requires a SOAP action or use of the WS-Addressing standard, you define your route as:
from("direct:example") .to("spring-ws:http://foo.com/bar?soapAction=http://foo.com&wsAddressingAction=http://bar.com")
You can also override the endpoint options with header values.
template.requestBodyAndHeader("direct:example", "<foobar xmlns=\"http://foo.com\"><msg>test message</msg></foobar>", SpringWebserviceConstants.SPRING_WS_SOAP_ACTION, "http://baz.com");
65.8. Using SOAP headers
You can provide the SOAP header as a Camel Message header when sending a message to a spring-ws endpoint. For example given the following SOAP header in a String:
String body = ... String soapHeader = "<h:Header xmlns:h=\"http://www.webserviceX.NET/\"><h:MessageID>1234567890</h:MessageID><h:Nested><h:NestedID>1111</h:NestedID></h:Nested></h:Header>";
We can set the body and header on the Camel Message as follows:
exchange.getIn().setBody(body); exchange.getIn().setHeader(SpringWebserviceConstants.SPRING_WS_SOAP_HEADER, soapHeader);
And then send the Exchange to a spring-ws
endpoint to call the Web Service.
Similarly, the spring-ws consumer also enriches the Camel Message with the SOAP header.
For an example see this unit test.
65.9. The header and attachment propagation
Spring WS Camel supports propagation of the headers and attachments into Spring-WS WebServiceMessage response. The endpoint uses a "hook" with the MessageFilter (default implementation is provided by BasicMessageFilter) to propagate the exchange headers and attachments into WebServiceMessage response.
exchange.getOut().getHeaders().put("myCustom","myHeaderValue") exchange.getIn().addAttachment("myAttachment", new DataHandler(...))
If the exchange header in the pipeline contains text, it generates Qname(key)=value attribute in the soap header. You must create a QName class directly and put any key into header.
65.10. How to transform the soap header using a stylesheet
The header transformation filter (HeaderTransformationMessageFilter.java) can be used to transform the soap header for a soap request. If you want to use the header transformation filter, see the below example:
<bean id="headerTransformationFilter" class="org.apache.camel.component.spring.ws.filter.impl.HeaderTransformationMessageFilter"> <constructor-arg index="0" value="org/apache/camel/component/spring/ws/soap-header-transform.xslt"/> </bean>
Use the bead defined above in the camel endpoint
<route> <from uri="direct:stockQuoteWebserviceHeaderTransformation"/> <to uri="spring-ws:http://localhost?webServiceTemplate=#webServiceTemplate&soapAction=http://www.stockquotes.edu/GetQuote&messageFilter=#headerTransformationFilter"/> </route>
65.11. How to use MTOM attachments
The BasicMessageFilter provides all required information for Apache Axiom in order to produce MTOM message. If you want to use Apache Camel Spring WS within Apache Axiom, here is an example: - Define the messageFactory
as shown below, and Spring-WS populates your SOAP message with optimized attachments through an MTOM strategy.
<bean id="axiomMessageFactory" class="org.springframework.ws.soap.axiom.AxiomSoapMessageFactory"> <property name="payloadCaching" value="false" /> <property name="attachmentCaching" value="true" /> <property name="attachmentCacheThreshold" value="1024" /> </bean>
- Add into your pom.xml the following dependencies
<dependency> <groupId>org.apache.ws.commons.axiom</groupId> <artifactId>axiom-api</artifactId> <version>1.2.13</version> </dependency> <dependency> <groupId>org.apache.ws.commons.axiom</groupId> <artifactId>axiom-impl</artifactId> <version>1.2.13</version> <scope>runtime</scope> </dependency>
- Add your attachment into the pipeline, for example using a Processor implementation.
private class Attachement implements Processor { public void process(Exchange exchange) throws Exception { exchange.getOut().copyFrom(exchange.getIn()); File file = new File("testAttachment.txt"); exchange.getOut().addAttachment("test", new DataHandler(new FileDataSource(file))); } }
- Define endpoint (producer) as ussual, for example like this:
from("direct:send") .process(new Attachement()) .to("spring-ws:http://localhost:8089/mySoapService?soapAction=mySoap&messageFactory=axiomMessageFactory");
- Your producer now generates MTOM messages with optimized attachments.
65.12. The custom header and attachment filtering
If you need to provide your custom processing of either headers or attachments, extend existing BasicMessageFilter and override the appropriate methods or write a brand new implementation of the MessageFilter interface.
To use your custom filter, add either a global or a local message filter into your spring context.
- a) the global custom filter that provides the global configuration for all Spring-WS endpoints
<bean id="messageFilter" class="your.domain.myMessageFiler" scope="singleton" />
or
- b) the local messageFilter directly on the endpoint as follows:
to("spring-ws:http://yourdomain.com?messageFilter=#myEndpointSpecificMessageFilter");
For more information see CAMEL-5724
If you want to create your own MessageFilter, consider overriding the following methods in the default implementation of MessageFilter in class BasicMessageFilter:
protected void doProcessSoapHeader(Message inOrOut, SoapMessage soapMessage) {your code /*no need to call super*/ } protected void doProcessSoapAttachements(Message inOrOut, SoapMessage response) { your code /*no need to call super*/ }
65.13. Using a custom MessageSender and MessageFactory
A custom message sender or factory in the registry can be referenced like this:
from("direct:example") .to("spring-ws:http://foo.com/bar?messageFactory=#messageFactory&messageSender=#messageSender")
Spring configuration:
<!-- authenticate using HTTP Basic Authentication --> <bean id="messageSender" class="org.springframework.ws.transport.http.HttpComponentsMessageSender"> <property name="credentials"> <bean class="org.apache.commons.httpclient.UsernamePasswordCredentials"> <constructor-arg index="0" value="admin"/> <constructor-arg index="1" value="secret"/> </bean> </property> </bean> <!-- force use of Sun SAAJ implementation, http://static.springsource.org/spring-ws/sites/1.5/faq.html#saaj-jboss --> <bean id="messageFactory" class="org.springframework.ws.soap.saaj.SaajSoapMessageFactory"> <property name="messageFactory"> <bean class="com.sun.xml.messaging.saaj.soap.ver1_1.SOAPMessageFactory1_1Impl"/> </property> </bean>
65.14. Exposing web services
To expose a web service using this component, you first must set up a MessageDispatcher to look for endpoint mappings in a Spring XML file. If you want to run inside a servlet container, you must use a MessageDispatcherServlet
configured in web.xml
.
By default the MessageDispatcherServlet
will look for a Spring XML named /WEB-INF/spring-ws-servlet.xml
. To use Camel with Spring-WS the only mandatory bean in that XML file is CamelEndpointMapping
. This bean allows the MessageDispatcher
to dispatch web service requests to your routes.
web.xml
<web-app> <servlet> <servlet-name>spring-ws</servlet-name> <servlet-class>org.springframework.ws.transport.http.MessageDispatcherServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>spring-ws</servlet-name> <url-pattern>/*</url-pattern> </servlet-mapping> </web-app>
spring-ws-servlet.xml
<bean id="endpointMapping" class="org.apache.camel.component.spring.ws.bean.CamelEndpointMapping" /> <bean id="wsdl" class="org.springframework.ws.wsdl.wsdl11.DefaultWsdl11Definition"> <property name="schema"> <bean class="org.springframework.xml.xsd.SimpleXsdSchema"> <property name="xsd" value="/WEB-INF/foobar.xsd"/> </bean> </property> <property name="portTypeName" value="FooBar"/> <property name="locationUri" value="/"/> <property name="targetNamespace" value="http://example.com/"/> </bean>
More information on setting up Spring-WS can be found in Writing Contract-First Web Services. Basically paragraph 3.6 "Implementing the Endpoint" is handled by this component (specifically paragraph 3.6.2 "Routing the Message to the Endpoint" is where CamelEndpointMapping
comes in). See the Spring Web Services Example included in the Camel distribution.
65.15. Endpoint mapping in routes
With the XML configuration in-place, you can now use Camel’s DSL to define what web service requests are handled by your endpoint:
The following route receives all web service requests that have a root element named "GetFoo" within the http://example.com/
namespace.
from("spring-ws:rootqname:{http://example.com/}GetFoo?endpointMapping=#endpointMapping") .convertBodyTo(String.class).to(mock:example)
The following route receives web service requests containing the http://example.com/GetFoo
SOAP action.
from("spring-ws:soapaction:http://example.com/GetFoo?endpointMapping=#endpointMapping") .convertBodyTo(String.class).to(mock:example)
The following route receives all requests sent to http://example.com/foobar
.
from("spring-ws:uri:http://example.com/foobar?endpointMapping=#endpointMapping") .convertBodyTo(String.class).to(mock:example)
The route below receives requests that contain the element <foobar>abc</foobar>
anywhere inside the message (and the default namespace).
from("spring-ws:xpathresult:abc?expression=//foobar&endpointMapping=#endpointMapping") .convertBodyTo(String.class).to(mock:example)
65.15.1. Alternative configuration, using existing endpoint mappings
For every endpoint with mapping-type beanname
one bean of type CamelEndpointDispatcher
with a corresponding name is required in the Registry/ApplicationContext. This bean acts as a bridge between the Camel endpoint and an existing endpoint mapping like PayloadRootQNameEndpointMapping
.
The use of the beanname
mapping-type is primarily meant for (legacy) situations where you are already using Spring-WS and have endpoint mappings defined in a Spring XML file. The beanname
mapping-type allows you to wire your Camel route into an existing endpoint mapping. When you are starting from the beginning, you must define your endpoint mappings as Camel URI’s (as illustrated above with endpointMapping
) since it requires less configuration and is more expressive. You can also use vanilla Spring-WS with the help of annotations.
An example of a route using beanname
:
<camelContext xmlns="http://camel.apache.org/schema/spring"> <route> <from uri="spring-ws:beanname:QuoteEndpointDispatcher" /> <to uri="mock:example" /> </route> </camelContext> <bean id="legacyEndpointMapping" class="org.springframework.ws.server.endpoint.mapping.PayloadRootQNameEndpointMapping"> <property name="mappings"> <props> <prop key="{http://example.com/}GetFuture">FutureEndpointDispatcher</prop> <prop key="{http://example.com/}GetQuote">QuoteEndpointDispatcher</prop> </props> </property> </bean> <bean id="QuoteEndpointDispatcher" class="org.apache.camel.component.spring.ws.bean.CamelEndpointDispatcher" /> <bean id="FutureEndpointDispatcher" class="org.apache.camel.component.spring.ws.bean.CamelEndpointDispatcher" />
65.16. POJO (un)marshalling
Camel’s pluggable data formats offer support for pojo/xml marshalling using libraries such as JAXB, XStream, JibX, Castor and XMLBeans. You can use these data formats in your route to sent and receive pojo’s to and from web services.
When accessing web services you can marshal the request and unmarshal the response message:
JaxbDataFormat jaxb = new JaxbDataFormat(false); jaxb.setContextPath("com.example.model"); from("direct:example").marshal(jaxb).to("spring-ws:http://foo.com/bar").unmarshal(jaxb);
Similarly, when providing web services, you can unmarshal XML requests to POJOs and marshal the response message back to XML:
from("spring-ws:rootqname:{http://example.com/}GetFoo?endpointMapping=#endpointMapping").unmarshal(jaxb) .to("mock:example").marshal(jaxb);
65.17. Spring Boot Auto-Configuration
When using spring-ws with Spring Boot use the following Maven dependency to have support for auto configuration:
<dependency> <groupId>org.apache.camel</groupId> <artifactId>camel-spring-ws</artifactId> <version>x.x.x</version> <!-- use the same version as your Camel core version --> </dependency>
The component supports 5 options that are listed below.
Name | Description | Default | Type |
---|---|---|---|
camel.component.spring-ws.autowired-enabled | Whether autowiring is enabled. This is used for automatic autowiring options (the option must be marked as autowired) by looking up in the registry to find if there is a single instance of matching type, which then gets configured on the component. This can be used for automatic configuring JDBC data sources, JMS connection factories, AWS Clients, etc. | true | Boolean |
camel.component.spring-ws.bridge-error-handler | Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored. | false | Boolean |
camel.component.spring-ws.enabled | Whether to enable auto configuration of the spring-ws component. This is enabled by default. | Boolean | |
camel.component.spring-ws.lazy-start-producer | Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages using Camel’s routing error handlers. When the first message is processed then creating and starting the producer takes time and prolong the total processing time of the processing. | false | Boolean |
camel.component.spring-ws.use-global-ssl-context-parameters | Enable usage of global SSL context parameters. | false | Boolean |
