淘淘商城08_权限管理及登录01

这里涉及5张表：用户表，用户角色表，角色表，权限表，角色权限表

登录功能：

package com.taotao.pojo;

import java.io.Serializable;

public class ActiveUser implements Serializable {
	private String userid;// 用户id 主键
	private String usercode;// 用户编码
	private String username;// 用户名称
	
	
	public String getUserid() {
		return userid;
	}
	public void setUserid(String userid) {
		this.userid = userid;
	}
	public String getUsercode() {
		return usercode;
	}
	public void setUsercode(String usercode) {
		this.usercode = usercode;
	}
	public String getUsername() {
		return username;
	}
	public void setUsername(String username) {
		this.username = username;
	}
	
	
	
}

使用逆向工程生成pojo类

业务逻辑:

用户名不存在

用户名或者密码错误.

成功以后,保存activeUser保存到session中.

用户不存在,用户名或者密码错误.在Controller里如何获取到这些提示信息呢?

先判断用户名,判断该用户不存给一个提示, 密码错误给一个提示.

要在service里就判断. 定义方法的返回类型应该是什么类型.

返回taotaoresult类型

ServiceImpl:

package com.taotao.service;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.util.DigestUtils;

import com.taotao.mapper.SysUserMapper;
import com.taotao.pojo.ActiveUser;
import com.taotao.pojo.SysUser;
import com.taotao.utils.TaotaoResult;

@Service
public class SysPermissionServiceImpl implements SysPermissionService {
	@Autowired
	private SysUserMapper sysUserMapper;

	@Override
	public TaotaoResult authenticat(String usercode, String password) {
		//1.获取该对象
		SysUser sysUser = this.getSysUser(usercode);
		//2.判断该用户 是否存在
		if (sysUser == null) {
			return TaotaoResult.build(400, "该用户不存在！");
		}
		
		//判断用户的密码
		//从数据库中取出该用户的密码，该密码是经过Md5加密的
		String pwd_db = sysUser.getPassword();
		//获取到该用户输入的密码，将输入的密码经过MD5加密
		String pwd_input = DigestUtils.md5DigestAsHex(password.getBytes());
		//与数据库中取出的密码相比较
		if (! pwd_db.equalsIgnoreCase(pwd_input)) {
			return TaotaoResult.build(400, "用户名或密码错误！");
		}
		
		//将数据添加到activeUser类中
		ActiveUser activeUser = new ActiveUser();
		activeUser.setUsercode(usercode);
		activeUser.setUsername(sysUser.getUsername());
		activeUser.setUserid(sysUser.getId());
		
		return TaotaoResult.ok(activeUser);
	}
	
	public SysUser getSysUser(String usercode){
		SysUser sysUser = new SysUser();    
		sysUser.getUsercode();
		List<SysUser> list = sysUserMapper.getSysUserByCode(usercode);
		if (list !=null && list.size() >0) {
			 return  list.get(0);
		}
		return null;
	}
}

添加dubbo的配置文件 applicationContext-service.xml

Controller:

package com.taotao.controller;

		ActiveUser  activeUser = (ActiveUser) result.getData();
