Question

I am currently using the Spring MVC, and I am trying to do some stuff with ajax. Basically what I want to do now is display the result from a controller dynamically on a webpage.

I.E. A user pushes a button it goes to the “whatever.do” controller and gets a list and displays that list without having to reload that page.

Anyway does anyone know any good tutorials or example projects?

It is very simple, I don’t even think a special tutorial is needed (apart from a generic spring-mvc one).

1. Make a @RequestMapping("/foo") method that returns a List<Foo>
2. Have <mvc:annotation-driven /> in your dispatcher-servlet.xml to activate handler mappings and convertors
3. Put Jackson (json serializer) on your classpath
4. Use $.getJSON("/foo", function(data) {..}); (jquery) – you will get a JSON-encoded list of your Foo objects

Spring will detect that the browser requests a json response, and converts your objects using Jackson.
