When marshalling a POJO to JSON XML you might want to exclude certain fields from the JSON XML output. With Jackson you can use JSON views to accomplish this. First create one or more marker classes.

{snippet:id=marker|lang=java|url=camel/trunk/components/camel-jacksonxml/src/test/java/org/apache/camel/component/jacksonxml/Views.java}

{snippet:id=jsonview|lang=java|url=camel/trunk/components/camel-jacksonxml/src/test/java/org/apache/camel/component/jacksonxml/TestPojoView.java}

{snippet:id=format|lang=java|url=camel/trunk/components/camel-jacksonxml/src/test/java/org/apache/camel/component/jacksonxml/JacksonMarshalViewTest.java}

{"<pojo age=":30," "weight=":70}"/>

Include/Exclude fields using the jsonView attribute with JacksonXMLDataFormat

...

    <dataFormats>
      <jacksonxml id="jsonjacksonxml" include="NOT_NULL"/>
    </dataFormats>

If you use jackson to unmarshal json XML to POJO, then you can now specify a header in the message that indicate which class name to unmarshal to.
The header has key CamelJacksonUnmarshalType if that header is present in the message, then Jackson will use that as FQN for the POJO class to unmarshal the XML payload as.

...

    <dataFormats>
      <jacksonxml id="jsonjacksonxml" allowJmsType="true"/>
    </dataFormats>

Unmarshalling from

...

XML to List<Map> or List<pojo>

If you are using Jackson to unmarshal XML to a list of map/pojo, you can now specify this by setting useList="true" or use the org.apache.camel.component.jacksonxml.ListJacksonXMLDataFormat. For example with Java you can do as shown below:

...

    <bean id="myJacksonModule" class="com.foo.MyModule">
      ... // configure the module as you want
    </bean>
 
    <dataFormats>
      <jacksonxml id="jsonjacksonxml" useList="true" unmarshalTypeName="com.foo.MyPojo" moduleRefs="myJacksonModule"/>
    </dataFormats>

...

 <dataFormats>
      <jacksonxml id="jsonjacksonxml" unmarshalTypeName="com.foo.MyPojo" disableFeatures="FAIL_ON_UNKNOWN_PROPERTIES"/>
 </dataFormats>

...

Using the prettyPrint option one can output a well formatted JSON while XML while marshalling:

 <dataFormats>
      <jacksonxml id="jack" prettyPrint="true"/>
 </dataFormats>
