本文深入探讨了Apache Shiro框架中如何进行权限和角色的判断，通过配置shiro_permis.ini文件来实现精细的权限控制。了解如何设置用户角色、分配权限，并在实际应用中进行验证。

shiro_permis.ini配置文件

[users]
java1234=123456,role1,role2
jack=123,role1
[roles]
role1=user:select
role2=user:select.user:add,user:delete,user:update

shiroutil.java 工具类

package com.java1234.shiro;

import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.AuthenticationException;
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 shiroutil {
	public static Subject SecurityUserlogi(String path,String user,String psw)throws AuthenticationException {
		Factory<SecurityManager> factory=new IniSecurityManagerFactory("classpath:"+path);
		//获取SecurityManager实例
		SecurityManager  securitymanager=factory.getInstance();
		//把SecurityManager实例绑定SecurityUtils
		SecurityUtils.setSecurityManager(securitymanager);
		//得到当前执行的账户
		Subject SecurityUser = SecurityUtils.getSubject();
		//创建令牌
		UsernamePasswordToken Token=new UsernamePasswordToken(user,psw);
		try {
		//身份验证
			SecurityUser.login(Token);
			System.out.println("登录成功");
		}catch(AuthenticationException e) {
			System.out.println("登录失败");
			e.printStackTrace();
		}
		return SecurityUser;
	}
}

测试文件
