public class HelloWorld {

    private static Logger logger = LogManager.getLogger(HelloWorld.class);

    private static Subject subject;

    static {
        //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.ini");
        //2、得到 SecurityManager 实例 并绑定给 SecurityUtils
        SecurityManager securityManager = factory.getInstance();
        SecurityUtils.setSecurityManager(securityManager);
        //3、得到 Subject 及创建用户名/密码身份验证 Token(即用户身份/凭证)
        subject = SecurityUtils.getSubject();
    }

    public static boolean login(String username,String password){
        UsernamePasswordToken token = new UsernamePasswordToken(username,password);
        //4、登录,即身份验证
        try {
            subject.login(token);
        }catch (Exception e){
            logger.info("身份验证失败");
            logger.error(e.getMessage(),e);
            return false;
        }

        return subject.isAuthenticated();//是否成功登陆

    }

    public static void main(String[] args) {

        //6、退出
        subject.logout();
    }
}

 

默认使用 的 Relam 是 IniRelam
