 Unmarshalling from json to List or List 
 Available as of Camel 2.14 
 If you are using Jackson to unmarshal json to a list of map/pojo, you can now specify this by setting useList="true" or use the org.apache.camel.component.jackson.ListJacksonDataFormat. For example with Java you can do as shown below: 



 Code Block




 
JacksonDataFormat format = new ListJacksonDataFormat();
// or
JacksonDataFormat format = new JacksonDataFormat();
format.useList();
// and you can specify the pojo class type also
format.setUnmarshalType(MyPojo.class);
 



 And if you use XML DSL then you configure to use list using useList attribute as shown below: 



 Code Block




 

  

 



 And you can specify the pojo type also

 Unmarshalling from json to POJO with dynamic class name 
 Available as of Camel 2.14 
 If you use jackson to unmarshal json 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 json payload as. Notice that behavior is enabled out of the box from Camel 2.14 onwards.  
  For JMS end users there is the JMSType header from the JMS spec that indicates that also. To enable support for JMSType you would need to turn that on, on the jackson data format as shown: 



 Code Block




 
JacksonDataFormat format = new JacksonDataFormat();
format.setAllowJmsType(true);
 



 Or from XML DSL you configure this as

 Setting serialization include option for Jackson marshal 
 Available as of Camel 2.13.3/2.14 
 If you want to marshal a pojo to JSON, and the pojo has some fields with null values. And you want to skip these null values, then you need to set either an annotation on the pojo,  



 Code Block




 
@JsonInclude(Include.NON_NULL)
public class MyPojo {
   ...
}
 



 But this requires you to include that annotation in your pojo source code. You can also configure the Camel JsonDataFormat to set the include option, as shown below: 



 Code Block




 
JacksonDataFormat format = new JacksonDataFormat();
format.setInclude("NON_NULL");

JSON
JSON is a Data Format to marshal and unmarshal Java objects to and from JSON. 

For JSON to object marshalling, Camel provides integration with three popular JSON libraries:

	The XStream library and Jettsion 
	The Jackson library
	Camel 2.10: The GSon library



By default Camel uses the XStream library. 

Direct, bi-directional JSON <=> XML conversionsAs of Camel 2.10, Camel supports direct, bi-directional JSON <=> XML conversions via the camel-xmljson data format, which is documented separately.

Using JSON data format with the XStream library


// lets turn Object messages into json then send to MQSeries
from("activemq:My.Queue").
  marshal().json().
  to("mqseries:Another.Queue");



Using JSON data format with the Jackson library


// lets turn Object messages into json then send to MQSeries
from("activemq:My.Queue").
  marshal().json(JsonLibrary.Jackson).
  to("mqseries:Another.Queue");



Using JSON data format with the GSON library


// lets turn Object messages into json then send to MQSeries
from("activemq:My.Queue").
  marshal().json(JsonLibrary.Gson).
  to("mqseries:Another.Queue");




Using JSON in Spring DSL
When using Data Format in Spring DSL you need to declare the data formats first. This is done in the DataFormats XML tag.




"jack" library="Jackson" unmarshalTypeName="org.apache.camel.component.jackson.TestPojo"/>




And then you can refer to this id in the route:


   
"direct:back"/>
"jack"/>
"mock:reverse"/>




Excluding POJO fields from marshalling
As of Camel 2.10
When marshalling a POJO to JSON you might want to exclude certain fields from the JSON output. With Jackson you can use JSON views to accomplish this. First create one or more marker classes.

public class Views {

static class Weight { }
static class Age { }
}



Use the marker classes with the @JsonView annotation to include/exclude certain fields. The annotation also works on getters.

@JsonView(Views.Age.class)
private int age = 30;

private int height = 190;

@JsonView(Views.Weight.class)
private int weight = 70;



Finally use the Camel JacksonDataFormat to marshall the above POJO to JSON.

JacksonDataFormat ageViewFormat = new JacksonDataFormat(TestPojoView.class, Views.Age.class);
from("direct:inPojoAgeView").marshal(ageViewFormat);



Note that the weight field is missing in the resulting JSON:


{"age":30, "height":190}



The GSON library supports a similar feature through the notion of ExclusionStrategies:

/**
 * Strategy to exclude {@link ExcludeAge} annotated fields
 */
protected static class AgeExclusionStrategy implements ExclusionStrategy {

@Override
public boolean shouldSkipField(FieldAttributes f) {
return f.getAnnotation(ExcludeAge.class) != null;
}

@Override
public boolean shouldSkipClass(Class clazz) {
return false;
}
}



The GsonDataFormat accepts an ExclusionStrategy in its constructor:

GsonDataFormat ageExclusionFormat = new GsonDataFormat(TestPojoExclusion.class, new AgeExclusionStrategy());
from("direct:inPojoExcludeAge").marshal(ageExclusionFormat);


The line above will exclude fields annotated with @ExcludeAge when marshalling to JSON.


Configuring field naming policy
Available as of Camel 2.11

The GSON library supports specifying policies and strategies for mapping from json to POJO fields. A common naming convention is to map json fields using lower case with underscores. 

We may have this JSON string


{
  "id" : 123,
  "first_name" : "Donald"
  "last_name" : "Duck"
}



Which we want to map to a POJO that has getter/setters as


public class PersonPojo {

private int id;
private String firstName;
private String lastName;

public int getId() {
return id;
}

public void setId(int id) {
this.id = id;
}

public String getFirstName() {
return firstName;
}

public void setFirstName(String firstName) {
this.firstName = firstName;
}

public String getLastName() {
return lastName;
}

public void setLastName(String lastName) {
this.lastName = lastName;
}
}

Excluding POJO fields from marshalling
As of Camel 2.10
When marshalling a POJO to JSON you might want to exclude certain fields from the JSON output. With Jackson you can use JSON views to accomplish this. First create one or more marker classes.

public class Views {

static class Weight { }
static class Age { }
}



Use the marker classes with the @JsonView annotation to include/exclude certain fields. The annotation also works on getters.

@JsonView(Views.Age.class)
private int age = 30;

private int height = 190;

@JsonView(Views.Weight.class)
private int weight = 70;



Finally use the Camel JacksonDataFormat to marshall the above POJO to JSON.

JacksonDataFormat ageViewFormat = new JacksonDataFormat(TestPojoView.class, Views.Age.class);
from("direct:inPojoAgeView").marshal(ageViewFormat);



Note that the weight field is missing in the resulting JSON:


{"age":30, "height":190}



The GSON library supports a similar feature through the notion of ExclusionStrategies:

/**
 * Strategy to exclude {@link ExcludeAge} annotated fields
 */
protected static class AgeExclusionStrategy implements ExclusionStrategy {

@Override
public boolean shouldSkipField(FieldAttributes f) {
return f.getAnnotation(ExcludeAge.class) != null;
}

@Override
public boolean shouldSkipClass(Class clazz) {
return false;
}
}



The GsonDataFormat accepts an ExclusionStrategy in its constructor:

GsonDataFormat ageExclusionFormat = new GsonDataFormat(TestPojoExclusion.class, new AgeExclusionStrategy());
from("direct:inPojoExcludeAge").marshal(ageExclusionFormat);


The line above will exclude fields annotated with @ExcludeAge when marshalling to JSON.

Dependencies for XStream

To use JSON in your camel routes you need to add the a dependency on camel-xstream which implements this data format. 

If you use maven you could just add the following to your pom.xml, substituting the version number for the latest & greatest release (see the download page for the latest versions).

JSON is a Data Format to marshal and unmarshal Java objects to and from JSON.

In Camel 2.0 we added support for more libraries:
Camel provides integration with three popular JSON libraries:

	The XStream library and Jettsion 
	The Jackson library
	Camel 2.10: The GSon library



By default Camel uses the XStream library. 

Using JSON data format with the XStream library


// lets turn Object messages into json then send to MQSeries
from("activemq:My.Queue").
  marshal().json().
  to("mqseries:Another.Queue");



Using JSON data format with the Jackson library


// lets turn Object messages into json then send to MQSeries
from("activemq:My.Queue").
  marshal().json(JsonLibrary.Jackson).
  to("mqseries:Another.Queue");



Using JSON data format with the GSON library


// lets turn Object messages into json then send to MQSeries
from("activemq:My.Queue").
  marshal().json(JsonLibrary.Gson).
  to("mqseries:Another.Queue");




Using JSON in Spring DSL
When using Data Format in Spring DSL you need to declare the data formats first. This is done in the DataFormats XML tag.
