How to remove null from JSON Output in JAXRS service , CXF 3.0.6 and jackson:2.9.1

[Kulbhushan Azad]

hi ,

i am trying to remove the null values from my json response,However , i am
not able to get it removed.
i am using CXF 3.0.6 and jackson:2.9.1.
How can i troubleshoot this? how do i see which jsonprovider is being used?
how can i get rid of the null values ?

i have a POJO with below annotation at the class level.

@JsonInclude(JsonInclude.Include.NON_NULL)

and below is the rest service spring configuration

<jaxrs:server id="testService" address="/test">
<jaxrs:serviceBeans>
<ref bean="testBean" />
</jaxrs:serviceBeans>
<jaxrs:extensionMappings>
<entry key="xml" value="application/xml" />
<entry key="text" value="application/text" />
<entry key="gzip" value="application/gzip" />
<entry key="octet-stream" value="application/octet-stream"
/>
</jaxrs:extensionMappings>
<jaxrs:providers>
<ref bean="jsonProvider" />
</jaxrs:providers>
<jaxrs:features>
<cxf:logging />
</jaxrs:features>
</jaxrs:server>

<bean id="jsonProvider"
class="com.fasterxml.jackson.jaxrs.json.JacksonJsonProvider" />

You can create a custom ObjectMapper where you set the
serializationInclusion property to NON_NULL. Then pass that to the
constructor for JacksonJsonProvider.

Hi,

For jackson:2.x

<jaxrs:providers>
<bean
class="com.fasterxml.jackson.jaxrs.json.JacksonJsonProvider">
<constructor-arg>
<bean
class="com.fasterxml.jackson.databind.ObjectMapper">
<property name="serializationInclusion"
value="NON_NULL" />
</bean>
</constructor-arg>
</bean>
...
</jaxrs:providers>
