         // The easiest way to create a Shiro SecurityManager with configured
         // realms, users, roles and permissions is to use the simple INI config.
         // We'll do that by using a factory that can ingest a .ini file and
         // return a SecurityManager instance:
    
         // Use the shiro.ini file at the root of the classpath
         // (file: and url: prefixes load from files and urls respectively):
         Factory<SecurityManager> factory = new IniSecurityManagerFactory("classpath:shiro.ini");
         SecurityManager securityManager = factory.getInstance();
    
         // for this simple example quickstart, make the SecurityManager
         // accessible as a JVM singleton.  Most applications wouldn't do this
         // and instead rely on their container configuration or web.xml for
         // webapps.  That is outside the scope of this simple quickstart, so
         // we'll just do the bare minimum so you can continue to get a feel
         // for things.
         SecurityUtils.setSecurityManager(securityManager);
    
         // Now that a simple Shiro environment is set up, let's see what you can do:
    
         // get the currently executing user:
         //获取当前的用户对象Subject
         Subject currentUser = SecurityUtils.getSubject();
    
         // Do some stuff with a Session (no need for a web or EJB container!!!)
         //通过当前用户拿到session
         Session session = currentUser.getSession();
         session.setAttribute("someKey", "aValue");
         String value = (String) session.getAttribute("someKey");
         if (value.equals("aValue")) {
             log.info("Retrieved the correct value! [" + value + "]");
         }
    
         // let's login the current user so we can check against roles and permissions:
         //判断当前的用户是否被认证
         if (!currentUser.isAuthenticated()) {
             //token:令牌
             UsernamePasswordToken token = new UsernamePasswordToken("lonestarr", "vespa");
             token.setRememberMe(true);//设置记住我
             try {
                 currentUser.login(token);//执行了登录操作
             } catch (UnknownAccountException uae) {
                 log.info("There is no user with username of " + token.getPrincipal());
             } catch (IncorrectCredentialsException ice) {
                 log.info("Password for account " + token.getPrincipal() + " was incorrect!");
             } catch (LockedAccountException lae) {
                 log.info("The account for username " + token.getPrincipal() + " is locked.  " +
                         "Please contact your administrator to unlock it.");
             }
             // ... catch more exceptions here (maybe custom ones specific to your application?
             catch (AuthenticationException ae) {
                 //unexpected condition?  error?
             }
         }
    
         //say who they are:
         //print their identifying principal (in this case, a username):
         log.info("User [" + currentUser.getPrincipal() + "] logged in successfully.");
    
         //test a role:
         if (currentUser.hasRole("schwartz")) {
             log.info("May the Schwartz be with you!");
         } else {
             log.info("Hello, mere mortal.");
         }
         //粗粒度
         //test a typed permission (not instance-level)
         if (currentUser.isPermitted("lightsaber:wield")) {
             log.info("You may use a lightsaber ring.  Use it wisely.");
         } else {
             log.info("Sorry, lightsaber rings are for schwartz masters only.");
         }
    
         //细粒度
         //a (very powerful) Instance Level permission:
         if (currentUser.isPermitted("winnebago:drive:eagle5")) {
             log.info("You are permitted to 'drive' the winnebago with license plate (id) 'eagle5'.  " +
                     "Here are the keys - have fun!");
         } else {
             log.info("Sorry, you aren't allowed to drive the 'eagle5' winnebago!");
         }
    
         //all done - log out!
         currentUser.logout();
    
         System.exit(0);
     }
    }

    shiro主要的几个方法,SpringSecurity都有

    Subject currentUser = SecurityUtils.getSubject();//获取当前的用户对象Subject
    Session session = currentUser.getSession();//通过当前用户拿到session
    currentUser.isAuthenticated();//判断当前的用户是否被认证
    currentUser.getPrincipal();//获得当前用户的认证
    currentUser.hasRole();//获得用户的角色
    currentUser.isPermitted();//获取用户的权限
    currentUser.logout();//注销
