A MappingJacksonJsonView (springframework ) and spring-json view comparison

Since release 3.0.0.M4 the springframework provides an own json-view - MappingJacksonJsonView. It is based on the Jackson Java JSON-processor   http://jackson.codehaus.org/.

The last release of the project was spring-json-1.3.0. http://spring-json.sourceforge.net/.  It  provides some more universal and advanced filter capilities.

For testing I used the modification spring-json demoapp and swapped the view components.

Here my comparison result:

The  strength of spring-json view the good integration to spring-mvc. It provides the same binding- and validation capabilities like we now from the JstlView. It supports the Custom(Value)ConverterRegistration and error- and exception-handling.

MappingJacksonJsonView is very fast and has a good annotation support.

Fazit:

spring-json view is well designed to swap a "classic" spring-mvc application to a Web 2.0
application just by changing the view while keeping the back-end
almost unchanged. If you start a new Web 2.0
application you can use your "old" spring-mvc knowledge to design complex json communication easily.

MappingJacksonJsonView is a very fast and quick to develope way for representing a model as a json-stream. no more and less. It strickly follows the new way of spring configuration by supporting spring-mvc and jackson anotations.
