Questions tagged [jsonserializer]

The JsonSerializer enables to control how objects are encoded into JSON. JSONSerializer will also pay attention to any method or field annotated by JSON.

JSONSerializer is the main class for performing serialization of Java objects to JSON. JSONSerializer by default performs a shallow serialization. While this might seem strange there is a method to this madness. Shallow serialization allows the developer to control what is serialized out of the object graph. This helps with performance, but more importantly makes good OO possible, fixes the circular reference problem, and doesn't require boiler plate translation code.

A simple example:

JSONSerializer serializer = new JSONSerializer();
return serializer.serialize( person );
