ssm框架

controller：

复制代码
package com.sgcc.controller;

import java.util.ArrayList;


import java.util.List;



import org.omg.CORBA.PUBLIC_MEMBER;


import org.springframework.stereotype.Controller;


import org.springframework.ui.ModelMap;


import org.springframework.web.bind.annotation.PathVariable;


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



import com.sgcc.entity.User;



@Controller


@RequestMapping("/user")//窄化--分模块开发，团队协作-- 注意页面跳转 加/ 或视图解析器


public class UserController {


private List<User> list = new ArrayList<User>();



public UserController() {


list.add(new User(1,"张三","1111"));


list.add(new User(2,"李四","1111"));


list.add(new User(3,"王五","3333"));


}


//查询所有用户


@RequestMapping("/list")


public String list(ModelMap map){


map.addAttribute("list", list);


//System.out.println(list.toString());


return "/list.jsp";


}


//添加用户


@RequestMapping("/add")


public String add(User user){


user.setId(list.get(list.size()-1).getId()+1);


list.add(user);


//return "/user/list.do"


return "redirect:list.do";


}


//删除用户


@RequestMapping("/delete")


public String delte(int id){


for (int i = 0; i < list.size(); i++) {


if (list.get(i).getId()id) {


list.remove(i);


break;


}


}


return "redirect:list.do";


}


//传统url delete？id=123；


//restful风格的开发 delete/123


//url /user/123/delete1


@RequestMapping("/{id}/delete1")


public String delete1(@PathVariable int id){


for (int i = 0; i < list.size(); i++) {


if (list.get(i).getId()id) {


list.remove(i);


break;


}


}


return "redirect:/user/list.do";


}


}
