Question

I have a Spring MVC form in jsp and I am having trouble getting the controller method invoked.

Can someone please explain to me the mechanism whereby Spring MVC performs controller method execution?

Answer 1

If you are using Spring 3 and annotations (recommended way of implementing controllers), the @RequestMapping(value=”exampleMapping.do”) specifies the method that will be executed. Here is an example:

@RequestMapping("/exampleMapping.do")
public String anExample(Model model) {
    // do some stuff
    return "someView";
}

So in this case, if your form submit target is exampleMapping.do, the method anExample will execute and return someView (which will resolve to your view folder containing a jsp named someView.jsp if you have your view resolver configured correctly).
