接一篇文章，今天上午实现了添加数据。以下是Jsp。里面主要是看newUser()和saveUser().注意这函数里的url，newUser()里面去掉url属性。还要注意的一个问题
这里面,<a href="#" >的#要改为javvascript:void(0); 这样才不会出现新建用户时找不到页面的情况。

UserController：package com.yang.bishe.controller;import java.util.List;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.ResponseBody;import org.springframework.web.servlet.ModelAndView;import com.yang.bishe.entity.Json;import com.yang.bishe.entity.User;import com.yang.bishe.service.interfaces.IUserService;@Controller@RequestMapping("/user")public class UserController extends BaseController { @Autowired private IUserService userService; @RequestMapping("/list") public ModelAndView goList(){ return new ModelAndView("user/list"); } @RequestMapping("/listUsers") public String listUser(HttpServletRequest request, HttpServletResponse response) throws Exception { // return "/views/index"; String hql="from User"; List users=userService.find(hql); // String result=userService.find(hql); writeJson(users,response); return null; } @RequestMapping("/addUser") public String addUser(User user,HttpServletRequest request, HttpServletResponse response) throws Exception{ Json json = new Json();//用于向前端发送消息 if(userService.getById(user.getUserId())!=null){ json.setMsg("新建用户失败，用户已存在！ "); }else{ userService.save(user); json.setMsg("新建用户成功！"); json.setSuccess(true); } writeJson(json,response); return null; } }
writeJson(json,response)这里是把消息传给前端页面。在script里面的函数里success:funciont(result);的result就存有controller里的json消息。
