public class MappingJackson2MessageConverter extends AbstractMessageConverter
MessageConverter implementation.
It customizes Jackson's default properties with the following ones:
MapperFeature.DEFAULT_VIEW_INCLUSION is disabledDeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES is disabledCompatible with Jackson 2.1 and higher.

ObjectMapper for this converter.
If not set, a default ObjectMapper is used.
Setting a custom-configured ObjectMapper is one way to take further
control of the JSON serialization process. For example, an extended
SerializerFactory can be
configured that provides custom serializers for specific types. The other
option for refining the serialization process is to use Jackson's provided
annotations on the types to be serialized, in which case a custom-configured
ObjectMapper is unnecessary.
public ObjectMapper getObjectMapper()
ObjectMapper for this converter.public void setPrettyPrint(boolean prettyPrint)
DefaultPrettyPrinter when writing JSON.
This is a shortcut for setting up an ObjectMapper as follows:
ObjectMapper mapper = new ObjectMapper(); mapper.configure(SerializationFeature.INDENT_OUTPUT, true); converter.setObjectMapper(mapper);
