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--分模塊開(kāi)發(fā)，團(tuán)隊(duì)協(xié)作-- 注意頁(yè)面跳轉(zhuǎn) 加/ 或視圖解析器 public class UserController {private List<User> list = new ArrayList<User>();public UserController() {list.add(new User(1,"張三","1111"));list.add(new User(2,"李四","1111"));list.add(new User(3,"王五","3333"));}//查詢所有用戶@RequestMapping("/list")public String list(ModelMap map){map.addAttribute("list", list);//System.out.println(list.toString());return "/list.jsp";}//添加用戶@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";}//刪除用戶@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";}//傳統(tǒng)url delete？id=123；//restful風(fēng)格的開(kāi)發(fā) 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";} }?
