Jackson JSON: Enabling Top Level Segment

Question

I mean this post: convert json to an object using jackson , and the last answer is StaxMan, which says that in Jackson 1.7 you can set the configuration so that Jackson starts to produce (and maybe parsing too?) Tag / segment top level in JSON.

Can someone shed some light on how to configure this configuration, and this is only for JSON generation or analysis?

Many thanks!

You need to create and configure ObjectMapperusing a function WRAP_ROOT_VALUElike

ObjectMapper objectMapper = new ObjectMapper();
objectMapper.configure(SerializationConfig.Feature.WRAP_ROOT_VALUE, true);

See javadoc :

, root ( JSON Object, ), JSON , " ", (, JAXB, @XmlRootElement.name) ( ). JAXB.

- false, .
