SpringBoot-32-shiro整合mybatis

9.8 shiro整合mybatis

在上一节springboot整合shiro工程的基础上导入整合数据库的依赖

注意：父工程是普通maven项目中导入的依赖，在子项目springboot中无法沿用

将之前整合mybatis的那一套直接搬过来（pojo/User,mapper/UserMapper,resource/mybatis/mapper/UserMapper.xml,），需要注意的是配置文件application.yml中配置项和UserMapper.xml路径的变动
项目结构图，-本demo的静态资源可以访问SpringBoot整合shiro项目静态资源下载

整合好后可以先测试一下,没问题后进行下面步骤

@SpringBootTest
class ShiroSpringbootApplicationTests {
    @Autowired
    UserMapper userMapper;
    @Test
    void contextLoads() {
        Map<String,String> map = new HashMap(15);
        map.put("id","20");
        User user = userMapper.getUser(map);
        System.out.println(user.toString());
    }

}
//User(id=20, name=李云, password=123456, email=123456@qq.com, birthday=Wed Aug 03 00:00:00 CST 2022)

然后需要改变自定义UserRealm类中的授权方法，将其改为从数据库查询后的结果

package com.example.config;

import com.example.mapper.UserMapper;
import com.example.pojo.User;
import org.apache.shiro.authc.*;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.util.StringUtils;

import java.util.HashMap;
import java.util.Map;

/**

 * @create 2022/8/5-19:45
 */
//自定义UserRealm extends AuthorizingRealm
public class UserRealm extends AuthorizingRealm {
    @Autowired
    UserMapper userMapper;
    //授权
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
        System.out.println("执行了授权doGetAuthorizationInfo方法！");
        return null;
    }

   //认证
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
        System.out.println("执行了认证doGetAuthenticationInfo方法！");
        //连接真实数据库
        UsernamePasswordToken userToken = (UsernamePasswordToken) token;
        Map<String,String> map = new HashMap(15);

        /*(String)userToken.getPrincipal() == userToken.getUsername()*/
        map.put("name",userToken.getUsername());
        User user = userMapper.getUser(map);

        if (user==null) {
            return null; //抛出UnknownAccountException异常
        }
        /*可以加密：
        MD5加密:e10adc3949ba59abbe56e057f20f883e
        MD5盐值加密（密码混合账户）： e10adc3949ba59abbe56e057f20f883eusername*/
        //密码认证，shiro做，加密了，默认是简单验证new SimpleCredentialsMatcher()明文验证
        return new SimpleAuthenticationInfo("",user.getPassword(),"");
    }
}

连接真实数据库后登陆时，如果账号是重名，那么生成token失败登陆失败

设置默认的密码加密规则在ShiroConfiguration配置类的第一步，注册自定义UserRealm指定密码验证规则

密码认证，shiro做，加密了，默认是简单验证new SimpleCredentialsMatcher()的明文验证

//第一步：创建Realm对象，需要自定义类
@Bean
public UserRealm userRealm(){
    UserRealm userRealm = new UserRealm();
    userRealm.setCredentialsMatcher(new Md5CredentialsMatcher());
    return userRealm;
}
