Castor is a Data Format which uses the Castor XML library to unmarshal an XML payload into Java objects or to marshal Java objects into an XML payload.
As usually you can use either Java DSL or Spring XML to work with Castor Data Format.
Using the Java DSL
Code Block |
---|
from("direct:order").
marshal().castor().
to("activemq:queue:order");
|
For example the following uses a named DataFormat of Castor which uses default Castor data binding features.
Code Block |
---|
CastorDataFormat castor = new CastorDataFormat ();
from("activemq:My.Queue").
unmarshal(castor).
to("mqseries:Another.Queue");
|
If you prefer to use a named reference to a data format which can then be defined in your Registry such as via your Spring XML file. e.g.
Code Block |
---|
from("activemq:My.Queue").
unmarshal("mycastorType").
to("mqseries:Another.Queue");
|
If you want to override default mapping schema by providing a mapping file you can set it as follows.
Code Block |
---|
CastorDataFormat castor = new CastorDataFormat ();
castor.setMappingFile("mapping.xml");
|
Also if you want to have more control on Castor Marshaller and Unmarshaller you can access them as below.
Code Block |
---|
castor.getMarshaller();
castor.getUnmarshaller();
|
Using Spring XML
The following example shows how to use Castor to unmarshal using Spring configuring the castor data type
Code Block |
---|
<camelContext id="camel" xmlns="http://camel.apache.org/schema/spring">
<route>
<from uri="direct:start"/>
<unmarshal>
<castor validation="true" />
</unmarshal>
<to uri="mock:result"/>
</route>
</camelContext>
|
This example shows how to configure the data type just once and reuse it on multiple routes. You have to set the <castor> element directly in <camelContext>.
Code Block |
---|
<camelContext>
<camelContext id="camel" xmlns="http://camel.apache.org/schema/spring">
<dataFormats>
<castor id="myCastor"/>
</dataFormats>
<route>
<from uri="direct:start"/>
<marshal ref="myCastor"/>
<to uri="direct:marshalled"/>
</route>
<route>
<from uri="direct:marshalled"/>
<unmarshal ref="myCastor"/>
<to uri="mock:result"/>
</route>
</camelContext>
