Class Jackson2ObjectMapperFactoryBean

java.lang.Object

org.springframework.yarn.integration.support.Jackson2ObjectMapperFactoryBean

All Implemented Interfaces:

org.springframework.beans.factory.FactoryBean<com.fasterxml.jackson.databind.ObjectMapper>, org.springframework.beans.factory.InitializingBean

public class Jackson2ObjectMapperFactoryBean
extends java.lang.Object
implements org.springframework.beans.factory.FactoryBean<com.fasterxml.jackson.databind.ObjectMapper>, org.springframework.beans.factory.InitializingBean

A FactoryBean for creating a Jackson ObjectMapper with setters to enable or disable Jackson features from within XML configuration.

In case there are no specific setters provided (for some rarely used options), you can still use the more general methods setFeaturesToEnable(Object[]) and setFeaturesToDisable(Object[]).

 <bean class="org.springframework.yarn.integration.support.Jackson2ObjectMapperFactoryBean">
   <property name="featuresToEnable">
     <array>
       <util:constant static-field="com.fasterxml.jackson.databind.SerializationFeature$WRAP_ROOT_VALUE"/>
       <util:constant static-field="com.fasterxml.jackson.databind.SerializationFeature$CLOSE_CLOSEABLE"/>
     </array>
   </property>
   <property name="featuresToDisable">
     <array>
       <util:constant static-field="com.fasterxml.jackson.databind.MapperFeature$USE_ANNOTATIONS"/>
     </array>
   </property>
 </bean>
 

Note: This BeanFctory is singleton, so if you need more than one you'll need to configure multiple instances.
