**一.maven的pom.xml:**

<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.tiglle</groupId>
      <artifactId>authorization</artifactId>
      <version>0.0.1-SNAPSHOT</version>
      <name>customRealm</name>
      <description>自定义realm</description>
    
        
       <dependencies>
        
        <dependency>
            <groupId>org.apache.shiro</groupId>
            <artifactId>shiro-core</artifactId>
            <version>1.3.2</version>
        </dependency>
        
        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-log4j12</artifactId>
            <version>1.7.12</version>
        </dependency>
        
        <dependency>
            <groupId>commons-logging</groupId>
            <artifactId>commons-logging</artifactId>
            <version>1.2</version>
        </dependency>
    
      </dependencies>
    
    </project>

**二.shior的ini配置文件shiro-persimmion.ini:**

# 用户 和 角色的配置
    [users]
    # 格式:
    # 用户名=密码,角色1,角色2,角色3,...
    wang=123,role1
    zhang=abc123,role1,role2
    
    # 角色的权限配置
    [roles]
    # 格式:角色1对资源user 1实例有create,update操作权限
    # 角色1=资源:权限:实例,资源:权限:实例,没有实例时默认为*所有实例
    # 细颗粒
    role1=user:create:1,user:update:1
    # 粗颗粒
    role2=user:create,user:delete
    role3=user:create

**三.log4j的配置文件log4j.properties:**

# Configure logging for testing: optionally with log file
    log4j.rootLogger=DEBUG, stdout
    # log4j.rootLogger=WARN, stdout, logfile
    
    log4j.appender.stdout=org.apache.log4j.ConsoleAppender
    log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
    log4j.appender.stdout.layout.ConversionPattern=%d %p [%c] - %m%n
    
    log4j.appender.logfile=org.apache.log4j.FileAppender
    log4j.appender.logfile.File=target/spring.log
    log4j.appender.logfile.layout=org.apache.log4j.PatternLayout
    log4j.appender.logfile.layout.ConversionPattern=%d %p [%c] - %m%n

**四.授权测试的java类ShiroMain.java:**

package com.tiglle.shiro;
    
    import java.util.ArrayList;
    import java.util.Arrays;
    
    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.apache.shiro.util.Factory;
    
    public class ShiroMain {
    
        public static void main(String[] args) {
            //1、获取SecurityManager工厂，此处使用Ini配置文件初始化SecurityManager
            Factory<SecurityManager> factory = new IniSecurityManagerFactory("classpath:shiro-persimmion.ini");
            //2、得到SecurityManager实例
            SecurityManager securityManager = factory.getInstance();
            // 并绑定给SecurityUtils  
            SecurityUtils.setSecurityManager(securityManager);
            //3、得到Subject
            Subject subject = SecurityUtils.getSubject();
            //创建用户名/密码身份验证Token（即用户身份/凭证）
            UsernamePasswordToken token = new UsernamePasswordToken("zhang","abc123");
    
            try {
                //4、登录，即主体身份验证  
                subject.login(token);
            } catch (Exception e) {
                //5、身份验证失败  
                e.printStackTrace();
            }
            boolean b = subject.isAuthenticated();
            System.out.println("身份验证结果:"+b);
    
            //先验证,在授权
            //1.基于角色的授权
            //判断主题是否有某角色
            boolean hasSomeRule = subject.hasRole("role1");
            System.out.println("单个角色判断:zhang是否拥有role1角色——"+hasSomeRule);
            //判断主体是否同时拥有多个角色
            boolean hasAllRules = subject.hasAllRoles(Arrays.asList("role1","role2"));
            System.out.println("多个角色判断:zhang是否同时拥有role1和role2角色——"+hasAllRules);
    
            //也可以使用check进行授权，授权失败会抛异常
            subject.checkRole("role1");
    
            //2.给予资源的授权
            //单个权限判断:是否对user的实例1有create操作
            boolean isPpermitted = subject.isPermitted("user:create:1");
            System.out.println("单个资源判断:zhang是否拥有user:create:1权限——"+isPpermitted);
            //多个权限判断
            boolean isPpermittedAll = subject.isPermittedAll("user:create:1","user:update:1");
            System.out.println("单个资源判断:zhang是否同时拥有user:create:1,user:update:1权限——"+isPpermittedAll);
    
            //也可以使用check进行授权，授权失败会抛异常
            subject.checkPermission("user:create:1");
    
            //6.退出
            subject.logout();
            System.out.println("退出后的身份验证结果:"+subject.isAuthenticated());
        }
    
    }
