shiro认证与授权

一.shiro认证方式-1(iniRealm)+授权

以maven项目为例
不采用数据库,只使用shiro.ini的配置文件

1.添加依赖

<dependencies>
        <dependency>
            <groupId>org.apache.shiro</groupId>
            <artifactId>shiro-core</artifactId>
            <version>1.3.2</version>
        </dependency>
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.12</version>
        </dependency>
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>8.0.19</version>
        </dependency>
    </dependencies>

添加依赖后的pom文件

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>com.ym</groupId>
    <artifactId>thirocode</artifactId>
    <version>1.0-SNAPSHOT</version>

    <dependencies>
        <dependency>
            <groupId>org.apache.shiro</groupId>
            <artifactId>shiro-core</artifactId>
            <version>1.4.2</version>
        </dependency>
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.12</version>
        </dependency>
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>8.0.19</version>
        </dependency>
    </dependencies>

</project>

2.在resources包下新建shiro.ini的文件

如果文件名是shiro.ini,并且在resources包下,,在认证的时候可以不指定shiro.ini的文件路径

[users]
zhenfu=zhenfu,admin,guest
caopi=caopi,guest
[roles]
admin=select,save,update,delete
guest=select,update

此为固定写法
- 必须是[users]和[roles]
- [users] 之后是 : 账户=密码,角色1,角色2
- [roles] 之后是 : 角色=权限1,权限2...

3.验证信息

package service;

import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.*;
import org.apache.shiro.mgt.DefaultSecurityManager;
import org.apache.shiro.realm.text.IniRealm;
import org.apache.shiro.subject.Subject;

import java.util.Arrays;
import java.util.List;
import java.util.Scanner;

public class TestShiro {
    public static void main(String[] args) {
        //1.构建securityManager环境
        DefaultSecurityManager securityManager =new DefaultSecurityManager();
        IniRealm iniRealm=new IniRealm("classpath:shiro.ini");
        //如果shiro.ini写在resources包下,可以不指定路径
        securityManager.setRealm(iniRealm);

        //2.将SecurityManager设置到运行环境中
        SecurityUtils.setSecurityManager(securityManager);

        //3.创建一个Subject实例，该实例认证需要使用上面创建的SecurityManager
        Subject subject = SecurityUtils.getSubject();

        Scanner input =new Scanner(System.in);
        System.out.println("请输入用户名:");
        String username=input.next();
        System.out.println("请输入密码:");
        String password=input.next();

        //创建token令牌,账号和密码是ini文件中配置的
        UsernamePasswordToken token=new UsernamePasswordToken(username,password);

        try {
            //4.用户登录
            subject.login(token);
        } catch (UnknownAccountException e) {
            //System.out.println("用户不存在");
            e.printStackTrace();
        }catch (IncorrectCredentialsException e) {
            //System.out.println("密码错误");
            e.printStackTrace();
        }catch (ExpiredCredentialsException e) {
            //System.out.println("凭证过期");
            e.printStackTrace();
        } catch (AuthenticationException e) {
            e.printStackTrace();
        }

        System.out.println("成功");

        //判断用户是否属于谋角色
        System.out.println("判断用户是否属于谋角色");
        System.out.println(subject.hasRole("admin"));
        System.out.println(subject.hasRole("guest"));

        List<String> roles= Arrays.asList("admin","guest");
        System.out.println(Arrays.toString(subject.hasRoles(roles)));

        //判断用户是否属于拥有谋权限
        System.out.println("判断用户是否属于拥有谋权限");
        System.out.println(subject.isPermitted("save"));
        System.out.println(subject.isPermitted("select"));

        System.out.println(Arrays.toString(subject.isPermitted("select","update","save")));
    }
}

二.shiro认证方式-2(jdbcRealm)

只是实现了简单的认证,并没有授权
和上一种认证方式采用的构建securityManager环境不同,新的shiro版本中IniSecurityManagerFactory已经废除,但是在第二种方式使用最新的就会报错,原因还在排查中,暂时使用老版本的shiro

1.添加依赖

    <dependencies>
        <dependency>
            <groupId>org.apache.shiro</groupId>
            <artifactId>shiro-core</artifactId>
            <version>1.3.2</version>
        </dependency>
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.12</version>
        </dependency>
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>8.0.19</version>
        </dependency>
        <!--shiro的jdbcRealm认证所需要的jar包-->
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-jdbc</artifactId>
            <version>4.3.6.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-simple</artifactId>
            <version>1.7.20</version>
            <!--<scope>compile</scope>-->
        </dependency>
    </dependencies>

添加完依赖后的pom文件

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>com.ym</groupId>
    <artifactId>shiro_jdbcRealm</artifactId>
    <version>1.0-SNAPSHOT</version>

    <dependencies>
        <dependency>
            <groupId>org.apache.shiro</groupId>
            <artifactId>shiro-core</artifactId>
            <version>1.3.2</version>
        </dependency>
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.12</version>
        </dependency>
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>8.0.19</version>
        </dependency>
        <!--shiro的jdbcRealm认证所需要的jar包-->
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-jdbc</artifactId>

        </dependency>
        <dependency>

            <!--<scope>compile</scope>-->
        </dependency>
    </dependencies>

</project>

2.2.在resources包下新建shiro.ini的文件

如果文件名是shiro.ini,并且在resources包下,,在认证的时候可以不指定shiro.ini的文件路径

[main]
dmds=org.springframework.jdbc.datasource.DriverManagerDataSource
dmds.url=jdbc:mysql://localhost:3307/rbac?useSSL=false&serverTimezone=UTC&characterEncoding=utf-8
dmds.username=root
dmds.password=root
dmds.driverClassName=com.mysql.cj.jdbc.Driver

jdbcRealm=org.apache.shiro.realm.jdbc.JdbcRealm
jdbcRealm.dataSource=$dmds
jdbcRealm.authenticationQuery=select password from user where username = ?

securityManager.realm=$jdbcRealm

3.测试类验证

package service;

import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.UsernamePasswordToken;
import org.apache.shiro.config.IniSecurityManagerFactory;
import org.apache.shiro.mgt.SecurityManager;
import org.apache.shiro.subject.Subject;
import org.junit.Test;


public class TestShiroJDBCRealm {

    //使用DefaultSecurityManager报错,但是使用IniSecurityManagerFactory就可以运行,原因排查中
    @Test
    public void testJDBCRealm(){
        // 构建SecurityManager工厂，IniSecurityManagerFactory可以从ini文件中初始化SecurityManager环境
        IniSecurityManagerFactory factory = new IniSecurityManagerFactory("classpath:shiro.ini");
        // 通过工厂创建SecurityManager
        SecurityManager manager = factory.getInstance();
        // 将SecurityManager设置到运行环境中
        SecurityUtils.setSecurityManager(manager);
        //创建一个Subject实例，该实例认证需要使用上面创建的SecurityManager
        Subject subject = SecurityUtils.getSubject();
        //创建token令牌
        UsernamePasswordToken token = new UsernamePasswordToken("yanm", "yanm");
        //用户登录
        subject.login(token);

        System.out.println("success");
    }
}
