一、准备工作

MyEclipse10，下载安装破解

JDK8下载安装，配置环境变量

MySQL5下载安装，配置环境变量

Tomcat8下载安装，配置环境变量

maven3.5下载安装，配置环境变量

在MyEclipse中设置preferences将jdk、tomcat、maven等配置好。这些网上教程很多，就不详说了。

二、项目结构

三、代码实现

配置信息

至此配置文件全部完成，当然配置文件中的一些地址、接口等都还未写，在开发中也不是这样的设计顺序。这里知识为了观看方便直接贴出来了。

后台代码：

1.UserController.java(->com.it.ssm.controller包下)

[code]package com.it.ssm.controller;

String pwd = request.getParameter("pwd");
String msg = null;
User user = userService.login(username);

}

4.UserMapper.java(->com.it.ssm.mapper包下)

[code]<?xml version="1.0" encoding="UTF-8"?>

5.IUserService .java(->com.it.ssm.service包下)

[code]package com.it.ssm.service;

import com.it.ssm.entity.User;

public interface IUserService {

public User login(String username);

}

6.UserServiceImpl .java(com.it.ssm.service.Impl包下)

[code]package com.it.ssm.service.Impl;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.it.ssm.dao.IUserDao;
import com.it.ssm.entity.User;
import com.it.ssm.service.IUserService;

@Service
public class UserServiceImpl implements IUserService {

@Autowired
private IUserDao userDao;

@Override
public User login(String username){
User user = userDao.getUserByName(username);
if (user != null) {
return user;
}else {
return null;
}
}

}

<h1>Congratulations! Log in successfully!</h1>
</div>
</body>
</html>

好啦大功告成！展示一下页面效果吧。

 输入正确的用户名盒密码之后即可登录成功。

这里没有写数据库的信息，可以根据配置信息自己建一个数据库，填写相关字段就ok了，也可以将jdbc中的数据库配置为自己的数据库，改好SQL语句，连接好就行了。

以上！
