5.创建实体类🥝

属性名与数据库字段名一一对应
在这里插入图片描述

package com.lzq.pojo;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

@Data
@NoArgsConstructor
@AllArgsConstructor
public class User {
    private Integer userid;
    private String username;
    private String userpwd;
    private String sex;
    private String address;
    private String salt;

}

6.创建dao层和mapper层🥝

这里只是为了测试项目，还没有进行编码工作

7.创建vo层实体类🥝

LoginVo

在这里插入图片描述

package com.lzq.vo;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

@Data
@NoArgsConstructor
@AllArgsConstructor
public class LoginVo {
    private String username;
    private String password;

}

8.dao层和 service层编码🥝

在这里插入图片描述

package com.lzq.dao;

import com.lzq.pojo.User;

public interface UserDao2 {
    User aaa(String username);

import com.lzq.pojo.User;
import com.lzq.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

@Service
public class UserServiceImpl implements UserService {
    @Autowired

        System.out.println(loginVo.getUsername());
        UsernamePasswordToken token = new UsernamePasswordToken(loginVo.getUsername(),loginVo.getPassword());
        try {
            subject.login(token);
            return "success";
        }catch (Exception e){

        }

    }
}

10.Realm层编码🥝

import org.springframework.beans.factory.annotation.Autowired;

public class MyRealm extends AuthorizingRealm {
    @Autowired
    private UserService userService;

    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
        return null;
    }

    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
        //从shiro框架权限管理器中获取用户名
        String username = token.getPrincipal().toString();
        //根据传入的用户名到数据库查找是否存在该用户信息
        User user = userService.findAllByusername(username);
        if (user != null) {
            //获取到盐  因为数据库中存储的密码都是加密过的解码需要盐
            ByteSource source = ByteSource.Util.bytes(user.getSalt());
            //将账户、密码、盐、给realm起的别名 交给 shiro框架处理比对
            SimpleAuthenticationInfo info = new SimpleAuthenticationInfo(user, user.getUserpwd(), source, this.getName());
            return info;
        }
        return null;
    }
}

    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
        //获取当前登录者的账号
        User user = (User) principals.getPrimaryPrincipal();
        //从数据库查询数据
        List<String> permissions =  userService.selectPermissionByuserid(user.getUserid());
        if (permissions.size()!=0){
            SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
            info.addStringPermissions(permissions);

        if (user != null) {
            //获取到盐  因为数据库中存储的密码都是加密过的解码需要盐
            ByteSource source = ByteSource.Util.bytes(user.getSalt());
            //将账户、密码、盐、给realm起的别名 交给 shiro框架处理比对
            SimpleAuthenticationInfo info = new SimpleAuthenticationInfo(user, user.getUserpwd(), source, this.getName());
            return info;

import java.util.stream.Collectors;

@Service
public class UserServiceImpl implements UserService {
    @Autowired
    private UserDao2 userDao;
    public User findAllByusername(String username) {
        User user = userDao.aaa(username);
        return user;
    }

    public List<String> selectPermissionByuserid(Integer userid) {
        List<Permission> permissions = userDao.selectpermissionByUserid(userid);
        List<String> collect = permissions.stream().map(item -> item.getPercode()).collect(Collectors.toList());
        return collect;
    }
}

3.userDao和映射🥝

<?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.lzq.dao.UserDao2">


    <select id="aaa" resultType="com.lzq.pojo.User">
            select * from user where username=#{username}

    </select>
    <select id="selectpermissionByUserid" resultType="com.lzq.pojo.Permission">
        select p.* from user_role ur join role_permission rp on ur.roleId=rp.roleid
                                     join permission p on rp.perid=p.perid where ur.userid=#{userId}
