1.User

package com.tgb.web.controller.entity;

public class User {
	
	private String userName;
	
	private String age;

	public String getUserName() {
		return userName;
	}

	public void setUserName(String userName) {
		this.userName = userName;
	}

	public String getAge() {
		return age;
	}

	public void setAge(String age) {
		this.age = age;
	}
}

Controller:

package com.tgb.web.controller.annotation;

import javax.servlet.http.HttpServletRequest;

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

@Controller
@RequestMapping("/user2")
public class User2Controller {
	
	@RequestMapping("/addUser")
	public String addUser(HttpServletRequest request){
		
		String result ="this is addUser------优化版";
		request.setAttribute("result", result);
		return "/jquery";
	}
	
	@RequestMapping("/delUser")
	public String delUser(HttpServletRequest request){
		String result ="this is delUser------优化版";
		request.setAttribute("result", result);
		return "/jquery";
	}
	@RequestMapping("/toUser")
	public String toUser(HttpServletRequest request){
		return "/jquery";
	}
}
