Dubbo实现登陆

一、目录展示

　　　　

二、dubbo_logins_service

　　2.1 实体类和service层

　　　　

　　2.2 logins实体类　　

package com.login.entity;

import java.io.Serializable;

public class logins implements Serializable {

    private Integer id;

    private String devcode;

    private String devname;

    private String devpassword;

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getDevcode() {
        return devcode;
    }

    public void setDevcode(String devcode) {
        this.devcode = devcode;
    }

    public String getDevname() {
        return devname;
    }

    public void setDevname(String devname) {
        this.devname = devname;
    }

    public String getDevpassword() {
        return devpassword;
    }

    public void setDevpassword(String devpassword) {
        this.devpassword = devpassword;
    }

    public logins(Integer id, String devcode, String devname, String devpassword) {
        this.id = id;
        this.devcode = devcode;
        this.devname = devname;
        this.devpassword = devpassword;
    }

    public logins() {
    }
}

　　2.3 loginsService层

package com.login.service;

public interface loginsService {
    logins checkLogin(logins login);
}

三、dubbo_logins

　　3.1 dao层、serviceImpl实现类、resource配置文件

　　　　

　　3.2 loginsDao（SQL在内）

package com.login.dao;

import com.login.entity.logins;
import org.apache.ibatis.annotations.Select;
import org.springframework.stereotype.Repository;

@Repository
public interface loginsDao {
    //登陆的方法
    @Select("select * from dev_user where devcode=#{devcode} and devpassword=#{devpassword}")
    logins checkLogin(logins login);
}

　　3.3 loginsImpl

package com.login.impl;

import com.login.dao.loginsDao;
import com.login.entity.logins;
import com.login.service.loginsService;
import org.springframework.stereotype.Service;

import javax.annotation.Resource;

@Service("loginsService")
public class loginsImpl implements loginsService {

    @Resource
    loginsDao loginsdao;

    @Override
    public logins checkLogin(logins login) {
        logins logins = loginsdao.checkLogin(login);
        if (logins!=null){
            if (logins.getDevpassword().equals(logins.getDevpassword())){
                return  logins;
            }
        }
        return null;
    }
}
