Can I user ModelAttribute in parent abstract class for controllers

Example:

class CommonController {

    @ModelAttribute("refs")
    public List getRef() {
       ...
    }

    @ModelAttribute("refs2")
    public List getRef2() {
       ...
    }
}

class MyControll开发者_如何学Pythoner extends CommonController {

    @RequestMapping("/my")
    public String request() {
        return "/my";
    }
}

The ModelAttribute objects will be available on my page?

Why you wouldn't recommend to do it?

For example - I have two controllers create and edit.

They use the same references getting through @ModelAttribute and instean to copy past it would be better to create parent class for controllers.

class ReferenceParentController {

    @ModelAttribute("refs")
    public List getRef() {
       ...
    }

    @ModelAttribute("refs2")
    public List getRef2() {
       ...
    }
}

class Create extends ReferenceParentController  {
    ...
}

class Edit extends ReferenceParentController  {
    ...
}

According to this answer in Spring forum you can:

But personally I wouldn't recommend to do it.
