搭建 SSM 项目

搭建 SSM 项目
–本人在学习 java 框架的时候,搭建了最基础的SSM项目,供大家学习;

首先看一下目录结构
POM文件:

<project xmlns="http://maven.apache.org/POM/4.0.0"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

配置文件主要有spring.xml,springMVC.xml,mybatis.xml

}

TestUserDao:

package com.kay.mall.dao;

public interface TestUserDao {
    public abstract void add(@Param("userId")String userId, @Param("userName")String userName);

</mapper>

数据库表结构:
访问地址:
访问过后的数据库:
差点忘记页面了!
页面的目录结构:

success.jsp:

<%@ page language="java" contentType="text/html; charset=UTF-8"
	pageEncoding="UTF-8"%>

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
<!-- 引入Jquery -->
<script src="static/js/jquery-3.3.1.min.js"></script>

<!-- 引入bootstrap -->
<link href="static/bootstrap-3.3.7-dist/css/bootstrap.min.css"
	rel="stylesheet">

<!-- 引入bootstrap.min.js -->
<script src="static/bootstrap-3.3.7-dist/js/bootstrap.min.js"></script>
</head>
<body>

	<h1>you are already successed</h1>

</body>
</html>
