4.3.3、测试至此已经完成了SSM三大框架的整合了，接下来测试一下，如果成功了，那么恭喜你，如果失败了，继续调试吧，作为程序员就是不停的与BUG做斗争！
4.3.3.1、新建jsp页面

文章插图

showUser.jsp 此页面仅输出一下用户名，完成一个完整的简单流程。
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><html>
<head>
<title>测试</title>
</head>

<body>
${user.userName}
</body></html>
4.3.3.2、建立UserController类UserController.java 控制器
package com.cn.hnust.controller;
import javax.annotation.Resource;import javax.servlet.http.HttpServletRequest;
import org.springframework.stereotype.Controller;import org.springframework.ui.Model;import org.springframework.web.bind.annotation.RequestMapping;
import com.cn.hnust.pojo.User;import com.cn.hnust.service.IUserService;
@Controller@RequestMapping("/user")public class UserController {
@Resource
private IUserService userService;

@RequestMapping("/showUser")
public String toIndex(HttpServletRequest request,Model model){
int userId = Integer.parseInt(request.getParameter("id"));
User user = this.userService.getUserById(userId);
model.addAttribute("user", user);
return "showUser";
}
}
4.3.3.3、部署项目输入地址： localhost:8080/ 项目名称 /user/showUser?id=1
