Can anyone post feedback on their experiences with various json libraries for java? In particular, does anyone have feedback on their experience with Google-gson?
(I'm aware that there's a nearly identical question here, but that's over a year old, so people may have different experiences now.)
I've used:
http://www.json.org/java/index.html
on a couple of projects. It's lightweight and efficient, and has stream-based handling for I/O.
We use GSON here. It's really simple to use and satisfies all our needs, we have basically the following, nothing more is needed:
/**
* Write given Java object as JSON to the output of the current response.
* @param object Any Java Object to be written as JSON to the output of the current response.
* @throws IOException If something fails at IO level.
*/
public void writeJson(Object object) throws IOException {
String json = new Gson().toJson(object);
this.response.setContentType("application/json");
this.response.setCharacterEncoding("UTF-8");
Writer writer = null;
try {
writer = this.response.getWriter();
writer.write(json);
} finally {
close(writer);
}
}
Our choice for GSON was based on the fact that its ideology fits our requirements, especially the full support of generic types. Besides that all it's also very performant.
