18.2. Provider Marshalers

Overview
링크 복사

Providers use an implementation of the org.apache.servicemix.jms.endpoints.JmsProviderMarshaler interface to convert normalized messages into JMS messages. The marshaler also converts the incoming reply from a JMS message into a normalized message. The JMS binding component comes with two provider marshaler implementations:
DefaultProviderMarshaler
The DefaultProviderMarshaler class provides the marshaler used by generic provider endpoints.
JmsSoapProviderMarshaler
The JmsSoapProviderMarshaler class provides the marshaler used by SOAP provider endpoints.
Note
The default SOAP marshaler does not support the full range of SOAP messages nor does it support marshaling map based messages into JMS messages.
When the default provider marshalers do not suffice for your application, you can provide a custom implementation of the JmsProviderMarshaler interface.

Implementing the marshaler

To create a custom provider marshaler, you implement the org.apache.servicemix.jms.endpoints.JmsProviderMarshaler interface. The JmsProviderMarshaler interface, shown in Example 18.4, “The Provider Marshaler Interface”, has two methods you need to implement:

Example 18.4. The Provider Marshaler Interface

public interface JmsProviderMarshaler
{
  Message createMessage(MessageExchange exchange, NormalizedMessage in, Session session) throws Exception;

  void populateMessage(Message message, MessageExchange exchange, NormalizedMessage normalizedMessage) throws Exception;
}

createMessage()
The createMessage() method uses information from the Red Hat JBoss Fuse core to generate a JMS message. Its parameters include the message exchange, the normalized message that is received by the provider, and the active JMS session.
populateMessage()
The populateMessage() method takes a JMS message and adds it to a message exchange for use by the Red Hat JBoss Fuse core.
Example 18.5, “Provider Marshaler Implementation” shows a simple provider marshaler implementation.

Example 18.5. Provider Marshaler Implementation

package com.widgetVendor.example;

import javax.jbi.messaging.MessageExchange;
import javax.jbi.messaging.NormalizedMessage;
import javax.jms.Message;
import javax.jms.Session;
import javax.jms.TextMessage;
import javax.xml.transform.Source;

import org.apache.servicemix.jbi.jaxp.SourceTransformer;
import org.apache.servicemix.jbi.jaxp.StringSource;
import org.apache.servicemix.jms.endpoints.JmsProviderMarshaler;

public class widgetProviderMarshaler implements JmsProviderMarshaler
{
    private SourceTransformer transformer = new SourceTransformer();
    
    public Message createMessage(MessageExchange exchange, NormalizedMessage in, Session session) throws Exception
    {
       TextMessage text = session.createTextMessage();
       text.setText(transformer.contentToString(in));
       return text;
    }

    public void populateMessage(Message message, MessageExchange exchange, NormalizedMessage normalizedMessage) throws Exception
    {
      TextMessage textMessage = (TextMessage) message;
      Source source = new StringSource(textMessage.getText());
      normalizedMessage.setContent(source);
    }
}

Configuring the provider
링크 복사

You configure a provider to use a custom marshaler using its marshaler attribute. The marshaler attribute's value is a reference to a bean element specifying the class of your custom marshaler implementation.
Example 18.6, “Configuring a Provider to Use a Customer Marshaler” shows configuration for a provider that uses a custom marshaler.

Example 18.6. Configuring a Provider to Use a Customer Marshaler

<beans xmlns:jms="http://servicemix.apache.org/jms/1.0"
       ... >
  ...
  <jms:soap-provider wsdl="classpath:widgets.wsdl"
                     destinationName="widgetQueue"
                     connectionFactory="#connectionFactory"
                     marshaler="#myProviderMarshaler" />

  <bean id="myProviderMarshaler" class="com.widgetVendor.example.widgetProviderMarshaler" />
  ...
</beans>

Note
You can also configure a provider to use a custom marshaler by adding a child marshaler element to the provider's configuration. The marshaler element simply wraps the bean element that configures the marshaler.
