Then we can configure the org.apache.camel.component.gson.GsonDataFormat in a Spring XML files as shown below. Notice we use fieldNamingPolicy property to set the field mapping. This property is an enum from GSon com.google.gson.FieldNamingPolicy which has a number of pre defined mappings. If you need full control you can use the property FieldNamingStrategy and implement a custom com.google.gson.FieldNamingStrategy where you can control the mapping.

<!-- define the gson data format, where we configure the data format using the properties -->
<bean id="gson" class="org.apache.camel.component.gson.GsonDataFormat">
<!-- we want to unmarshal to person pojo -->
<property name="unmarshalType" value="org.apache.camel.component.gson.PersonPojo"/>
<!-- we want to map fields to use lower case and underscores -->
<property name="fieldNamingPolicy" value="LOWER_CASE_WITH_UNDERSCORES"/>
</bean>

And use it in Camel routes by referring to its bean id as shown:

As an example of using this attribute you can instead of:
![]() Code Block |
|
|
JacksonDataFormat ageViewFormat = new JacksonDataFormat(TestPojoView.class, Views.Age.class);
from("direct:inPojoAgeView").
marshal(ageViewFormat);
|
Directly specify your JSON view inside the Java DSL as:
![]() Code Block |
|
|
from("direct:inPojoAgeView").
marshal().json(TestPojoView.class, Views.Age.class);
|
And the same in XML DSL:
![]() Code Block |
| java
|
<from uri="direct:inPojoAgeView"/>
<marshal>
<json library="Jackson" unmarshalTypeName="org.apache.camel.component.jackson.TestPojoView" jsonView="org.apache.camel.component.jackson.Views$Age"/>
</marshal>
