Execute a method before any Handler in Controller

[namero999]

Hello everyone,

I'm looking for a way to have a method executed before any Handler in a given Controller. Something like

@Controller
@RequestMapping(value = "/{x}")
class MyController {

  @PreDispatch // this is a totally invented annotation just to give you an idea
  private void aMethod(@PathVariable String x) {
    ...
  }

  @RequestMapping(value = "/handler")
  public String handler(@PathVariable String x, Model model) {
    ...
  }

}

So that when I go to /{x}/handler, for any {x}, I have my "PreDispatch" method invoked, do some processing on x, and than have the regular handler invoked.

Right now, I have all my handlers that execute the "preDispatch" method as the first line of code, and I would like to have this behaviour "automatized".

If there's no way to have this behaviour via SpringMVC probably I have to use AOP.

Thank you very much

That is basically why there are HandlerInterceptors.
