Chapter 139. Salesforce

Salesforce component

Available as of Camel 2.12
This component lets producer and consumer endpoints communicate with Salesforce by using Java DTOs. There is a companion Maven plugin, Camel Salesforce Plugin, that generates these DTOs (see further below).
To configure a camel-salesforce component to use Transport Layer Security (TLS), see chapter "Configuring Transport Security for Camel Components" in "Security Guide".
Maven users will need to add the following dependency to their pom.xml: 
<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-salesforce</artifactId>
    <version>x.x.x</version>
    <!-- use the same version as your Camel core version -->
</dependency>

Camel on EAP deployment

This component is supported by the Camel on EAP (Wildfly Camel) framework, which offers a simplified deployment model on the Red Hat JBoss Enterprise Application Platform (JBoss EAP) container. For details of this model, see chapter "Apache Camel on JBoss EAP" in "Deploying into a Web Server".

URI format

The URI scheme for a salesforce component is as follows 
salesforce:topic?options
You can append query options to the URI in the following format, ?option=value&option=value&...

Supported Salesforce APIs

The component supports the following Salesforce APIs
Producer endpoints can use the following APIs. Most of the APIs process one record at a time, the Query API can retrieve multiple Records.

Rest API

  • getVersions - Gets supported Salesforce REST API versions
  • getResources - Gets available Salesforce REST Resource endpoints
  • getGlobalObjects - Gets metadata for all available SObject types
  • getBasicInfo - Gets basic metadata for a specific SObject type
  • getDescription - Gets comprehensive metadata for a specific SObject type
  • getSObject - Gets an SObject using its Salesforce Id
  • createSObject - Creates an SObject
  • updateSObject - Updates an SObject using Id
  • deleteSObject - Deletes an SObject using Id
  • getSObjectWithId - Gets an SObject using an external (user defined) id field
  • upsertSObject - Updates or inserts an SObject using an external id
  • deleteSObjectWithId - Deletes an SObject using an external id
  • query - Runs a Salesforce SOQL query
  • queryMore - Retrieves more results (in case of large number of results) using result link returned from the 'query' API
  • search - Runs a Salesforce SOSL query
For example, the following producer endpoint uses the upsertSObject API, with the sObjectIdName parameter specifying 'Name' as the external id field. The request message body should be an SObject DTO generated using the maven plugin. The response message will either be null if an existing record was updated, or CreateSObjectResult with an id of the new record, or a list of errors while creating the new object. 
...to("salesforce:upsertSObject?sObjectIdName=Name")...

Rest Bulk API

Producer endpoints can use the following APIs. All Job data formats, i.e. xml, csv, zip/xml, and zip/csv are supported. The request and response have to be marshalled/unmarshalled by the route. Usually the request will be some stream source like a CSV file, and the response may also be saved to a file to be correlated with the request.
  • createJob - Creates a Salesforce Bulk Job
  • getJob - Gets a Job using its Salesforce Id
  • closeJob - Closes a Job
  • abortJob - Aborts a Job
  • createBatch - Submits a Batch within a Bulk Job
  • getBatch - Gets a Batch using Id
  • getAllBatches - Gets all Batches for a Bulk Job Id
  • getRequest - Gets Request data (XML/CSV) for a Batch
  • getResults - Gets the results of the Batch when its complete
  • createBatchQuery - Creates a Batch from an SOQL query
  • getQueryResultIds - Gets a list of Result Ids for a Batch Query
  • getQueryResult - Gets results for a Result Id
For example, the following producer endpoint uses the createBatch API to create a Job Batch. The in message must contain a body that can be converted into an InputStream (usually UTF-8 CSV or XML content from a file, etc.) and header fields 'jobId' for the Job and 'contentType' for the Job content type, which can be XML, CSV, ZIP\_XML or ZIP\_CSV. The put message body will contain BatchInfo on success, or throw a SalesforceException on error. 
...to("salesforce:createBatchJob")..

Rest Streaming API

Consumer endpoints can use the following sytax for streaming endpoints to receive Salesforce notifications on create/update.
To create and subscribe to a topic 
from("salesforce:CamelTestTopic?notifyForFields=ALL&notifyForOperations=ALL&sObjectName=Merchandise__c&updateTopic=true&sObjectQuery=SELECT Id, Name FROM Merchandise__c")...
To subscribe to an existing topic 
from("salesforce:CamelTestTopic&sObjectName=Merchandise__c")...

Uploading a document to a ContentWorkspace

Create the ContentVersion in Java, using a Processor instance: 
public class ContentProcessor implements Processor {
    public void process(Exchange exchange) throws Exception {
        Message message = exchange.getIn();
 
        ContentVersion cv = new ContentVersion();
        ContentWorkspace cw = getWorkspace(exchange);
        cv.setFirstPublishLocationId(cw.getId());
        cv.setTitle("test document");
        cv.setPathOnClient("test_doc.html");
        byte[] document = message.getBody(byte[].class);
        ObjectMapper mapper = new ObjectMapper();
        String enc = mapper.convertValue(document, String.class);
        cv.setVersionDataUrl(enc);
        message.setBody(cv);
    }
 
    protected ContentWorkspace getWorkSpace(Exchange exchange) {
        // Look up the content workspace somehow, maybe use enrich() to add it to a
        // header that can be extracted here
        ....
    }
}
Give the output from the processor to the Salesforce component: 
from("file:///home/camel/library")
    .to(new ContentProcessor())     // convert bytes from the file into a ContentVersion SObject
                                    // for the salesforce component
    .to("salesforce:createSObject");

Camel Salesforce Maven Plugin

This Maven plug-in generates DTOs for the Camel Salesforce.

Usage

The plug-in configuration has the following properties.
Option Description
clientId Salesforce client Id for Remote API access.
clientSecret Salesforce client secret for Remote API access.
userName Salesforce account user name.
password Salesforce account password (including secret token).
version Salesforce Rest API version, defaults to 34.0.
outputDirectory Directory where to place generated DTOs, defaults to ${project.build.directory}/generated-sources/camel-salesforce.
includes List of SObject types to include.
excludes List of SObject types to exclude.
includePattern Java RegEx for SObject types to include.
excludePattern Java RegEx for SObject types to exclude.
packageName Java package name for generated DTOs, defaults to org.apache.camel.salesforce.dto. 
mvn camel-salesforce:generate -DclientId=<clientid> -DclientSecret=<clientsecret> -DuserName=<username> -Dpassword=<password>
The generated DTOs use Jackson and XStream annotations. All Salesforce field types are supported. Date and time fields are mapped to Joda DateTime, and picklist fields are mapped to generated Java Enumerations.
