结构：

 实体类：

package com.dubboserver.entity;


import java.io.Serializable;

public class Users implements Serializable {
    private int uid;
    private String userName;
    private String password;
    private String realName;

    public int getUid() {
        return uid;
    }

    public void setUid(int uid) {
        this.uid = uid;
    }

    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public String getRealName() {
        return realName;
    }

    public void setRealName(String realName) {
        this.realName = realName;
    }
}

　　注意：因为是两个项目所以实体类要实现Serializable 接口

Dao层：

package com.dubboserver.dao;


import com.dubboserver.entity.Users;
import org.apache.ibatis.annotations.Param;
import org.springframework.stereotype.Repository;

@Repository("iUserDao")
public interface IUserDao {
    //登录
    Users login(@Param("username") String username);
}

Dao层的实现mapper：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.dubboserver.dao.IUserDao">
    <!-- 目的：为dao接口方法提供sql语句配置 -->
    <select id="login" resultType="Users" >
        <!-- 具体的sql -->
        select  * from  users where  userName=#{username}
    </select>


</mapper>

　　service层：

package com.dubboserver.service;

import com.dubboserver.entity.Users;


public interface IUserService {

    //登录
    Users login(String username, String password);
}

　　service层实现：

package com.dubboserver.service.impl;


import com.dubboserver.dao.IUserDao;
import com.dubboserver.entity.Users;
import com.dubboserver.service.IUserService;
import org.springframework.stereotype.Service;

import javax.annotation.Resource;

@Service("iUserService")
public class IUserServiceImpl implements IUserService {

    @Resource(name = "iUserDao")
    private IUserDao iUserDao;


    @Override
    public Users login(String username, String password) {
        Users login = iUserDao.login(username);
        if (login!=null && login.getPassword().equals(password) ){
            return login;
        }
        return null;
    }
}
