5、Shiro之jdbcRealm认证授权

登录认证:

注意,下面我是以连接orcal数据库为例的依赖,如果各位同仁使用的是骑她数据库,可以换成对应数据库的依赖(数据源不用换)

Pom.xml增加依赖:

<!--引入连接orcal的jar包-->
<!-- oracle驱动 -->
<!-- https://mvnrepository.com/artifact/com.oracle/ojdbc14 -->
<dependency>
    <groupId>com.oracle</groupId>
    <artifactId>ojdbc7</artifactId>
    <version>7.0.0</version>
</dependency>
<!--引入数据源-->
<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>druid</artifactId>
    <version>1.1.6</version>
</dependency>

新建名为JdbcRelamTes的t测试类:

JdbcRelamTest.java代码:

package com.shiro.shiroframe;

import com.alibaba.druid.pool.DruidDataSource;
import org.apache.catalina.security.SecurityUtil;
import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.UsernamePasswordToken;
import org.apache.shiro.mgt.DefaultSecurityManager;
import org.apache.shiro.realm.jdbc.JdbcRealm;
import org.apache.shiro.subject.Subject;
import org.junit.jupiter.api.Test;

public class JdbcRelamTest {
    DruidDataSource druidDataSource = new DruidDataSource();

    {
        druidDataSource.setUrl("jdbc:oracle:thin:@localhost:1521:ORCL");
        druidDataSource.setUsername("testyanshemiyue");//你的数据库账号
        druidDataSource.setPassword("testhourumiyu");//你的数据库密码
    }

    @Test
    public void JdbcRelamTest() {
        JdbcRealm jdbcRealm = new JdbcRealm();
        jdbcRealm.setDataSource(druidDataSource);
        DefaultSecurityManager defaultSecurityManager = new DefaultSecurityManager();
        defaultSecurityManager.setRealm(jdbcRealm);
        SecurityUtils.setSecurityManager(defaultSecurityManager);
        Subject subject = SecurityUtils.getSubject();
        UsernamePasswordToken usernamePasswordToken = new UsernamePasswordToken("miyue", "houru");
        subject.login(usernamePasswordToken);
        System.err.println(subject.isAuthenticated());//true
    }
}

数据库创建表users并插入一条测试数据:

运行java代码:

如果账号密码正确打印结果为true,否则报错

 补充:问什么要建users表?

下面是JdbcRealm类的源码:

在我们没有自己创建Sql语句时JdbcRealm会使用她自己定义的SQL语句,所以我们就根据此建表测试即可

角色认证和权限认证:

首先我们在数据库建立角色表和角色权限表并插入数据:

java代为:

package com.shiro.shiroframe;

import com.alibaba.druid.pool.DruidDataSource;
import org.apache.catalina.security.SecurityUtil;
import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.UsernamePasswordToken;
import org.apache.shiro.mgt.DefaultSecurityManager;
import org.apache.shiro.realm.jdbc.JdbcRealm;
import org.apache.shiro.subject.Subject;
import org.junit.jupiter.api.Test;

public class JdbcRelamTest {
    DruidDataSource druidDataSource = new DruidDataSource();

    {
        druidDataSource.setUrl("jdbc:oracle:thin:@localhost:1521:ORCL");
        druidDataSource.setUsername("luzhanshi");
        druidDataSource.setPassword("admin123");
    }

    @Test
    public void JdbcRelamTest() {
        JdbcRealm jdbcRealm = new JdbcRealm();
        jdbcRealm.setDataSource(druidDataSource);

        //开启查询权限的开关(默认是关闭的)否则Shiro是不会去查询权限数据的
        jdbcRealm.setPermissionsLookupEnabled(true);

        DefaultSecurityManager defaultSecurityManager = new DefaultSecurityManager();
        defaultSecurityManager.setRealm(jdbcRealm);
        SecurityUtils.setSecurityManager(defaultSecurityManager);
        Subject subject = SecurityUtils.getSubject();
        UsernamePasswordToken usernamePasswordToken = new UsernamePasswordToken("miyue", "houru");
        //登录认证
        subject.login(usernamePasswordToken);
        System.err.println(subject.isAuthenticated());//true
        //角色认证:验证miyue是否具有admin角色
        subject.checkRole("admin");
        //权限认证:验证admin角色是否具有user:select权限
        subject.checkRoles("admin","user");
        subject.checkPermission("user:select");
    }
}

执行java代码,验证通过控制台不报错,否则控制台报错

 JdbcRelam自定义SQL:

如果上面涉及到的三个表是我们自定义的表名,那就要我们自己修改SQL语句了:

1、如下图我们按照上面建表的过程一样,新建了三张和上面一样,但是名字不一样的表:

那么我们的对应的java代码就要修改对应的SQL:代码如下:

package com.shiro.shiroframe;

import com.alibaba.druid.pool.DruidDataSource;
import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.UsernamePasswordToken;
import org.apache.shiro.mgt.DefaultSecurityManager;
import org.apache.shiro.realm.jdbc.JdbcRealm;
import org.apache.shiro.subject.Subject;
import org.junit.jupiter.api.Test;

public class JdbcRelamTest {
    DruidDataSource druidDataSource = new DruidDataSource();

    {
        druidDataSource.setUrl("jdbc:oracle:thin:@localhost:1521:ORCL");
        druidDataSource.setUsername("luzhanshi");
        druidDataSource.setPassword("admin123");
    }

    @Test
    public void JdbcRelamTest() {
        JdbcRealm jdbcRealm = new JdbcRealm();
        jdbcRealm.setDataSource(druidDataSource);

        //开启查询权限的开关(默认是关闭的)否则Shiro是不会去查询权限数据的
        jdbcRealm.setPermissionsLookupEnabled(true);
        //创建自定义SQL
        String sql ="SELECT PASSWORD FROM TESTUSER WHERE USERNAME=?";
        String roleSql ="SELECT ROLE_NAME FROM Test_USER_ROLES WHERE USERNAME = ?";
        String rolePermissionSql ="SELECT PERMISSION FROM TEST_ROLES_PERMISSIONS WHERE ROLE_NAME = ?";
        jdbcRealm.setAuthenticationQuery(sql);
        jdbcRealm.setUserRolesQuery(roleSql);
        jdbcRealm.setPermissionsQuery(rolePermissionSql);
        DefaultSecurityManager defaultSecurityManager = new DefaultSecurityManager();
        defaultSecurityManager.setRealm(jdbcRealm);
        SecurityUtils.setSecurityManager(defaultSecurityManager);
        Subject subject = SecurityUtils.getSubject();
        UsernamePasswordToken usernamePasswordToken = new UsernamePasswordToken("miyue", "houru");
        //登录认证
        subject.login(usernamePasswordToken);
        System.err.println(subject.isAuthenticated());//true
//        //角色认证:验证miyue是否具有admin角色
        subject.checkRole("admin");
//        //权限认证:验证admin角色是否具有user:select权限
        subject.checkRoles("admin","user");
        subject.checkPermission("user:select");
    }
}
