Spring Multi-Action Using Annotation Tutorial

To group related actions into a single controller class using Spring annotations use the @RequestMapping annotation at the method level instead of class level. The UserController class with the add() and the remove() method is shown below.

package com.vaannila.web;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

@Controller
public class UserController {
	
	@RequestMapping("/user/add.htm")
	public ModelAndView add() {
		System.out.println("Add method called");
		return new ModelAndView("user", "message", "Add method called");
	}
	
	@RequestMapping("/user/remove.htm")
	public ModelAndView remove() {
		System.out.println("Remove method called");
		return new ModelAndView("user", "message", "Remove method called");
	}
}

 To handle multiple action in a single controller class, that is the only change you need to do.

In the redirect.jsp page we have two urls one to call the add() method and the other to call the remove() method.

<a href="user/add.htm" >Add</a>&ltbr&gt
<a href="user/remove.htm" >Remove</a> 

You can download and try the example here.
