Content Filter
Camel supports the Content Filter from the EIP patterns using one of the following mechanisms in the routing logic to transform content from the inbound message.
- Message Translator
- invoking a Java bean
- Processor object
A common way to filter messages is to use an Expression in the DSL like XQuery, SQL or one of the supported Scripting Languages.
Using the Fluent Builders
Here is a simple example using the DSL directly
| Wiki Markup |
|---|
{snippet:id=example|lang=java|url=camel/trunk/camel-core/src/test/java/org/apache/camel/processor/TransformViaDSLTest.java} |
In this example we add our own Processor
| Wiki Markup |
|---|
{snippet:id=example|lang=java|url=camel/trunk/camel-core/src/test/java/org/apache/camel/processor/TransformTest.java} |
For further examples of this pattern in use you could look at one of the JUnit tests
Using Spring XML
| Code Block |
|---|
<route> <from uri="activemq:Input"/> <bean ref="myBeanName" method="doTransform"/> <to uri="activemq:Output"/> </route> |
You can also use XPath to filter out part of the message you are interested in:
| Code Block |
|---|
<route> <from uri="activemq:Input"/> <setBody><xpath resultType="org.w3c.dom.Document">//foo:bar</xpath></setBody> <to uri="activemq:Output"/> </route> |
