        // 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subject   SecurityUtils.getSubject()        Subject currentUser = SecurityUtils.getSubject();
        // Do some stuff with a Session (no need for a web or EJB container!!!)        //获取session        Session session = currentUser.getSession();        //放入属性        session.setAttribute("someKey", "aValue");        //验证是否取到
        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:        //测试是否被认证        if (!currentUser.isAuthenticated()) {            //用户名密码封装            UsernamePasswordToken token = new UsernamePasswordToken("lonestarr", "vespa");            //记住我            token.setRememberMe(true);            try {                //执行登录                currentUser.login(token);                //如果没有指定的用户            } catch (UnknownAccountException uae) {                log.info("There is no user with username of " + token.getPrincipal());                //密码错误            } catch (IncorrectCredentialsException ice) {                log.info("Password for account " + token.getPrincipal() + " was incorrect!");                //用户被锁定            } 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?            //总的认证异常处理            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:        //测试是否有某一个角色        if (currentUser.hasRole("schwartz")) {            log.info("May the Schwartz be with you!");        } else {            log.info("Hello, mere mortal.");        }
        //test a typed permission (not instance-level)        //测试用户是否有一个行为  weild        //isPermitted   The 'schwartz' role can do anything (*) with any lightsaber:        if (currentUser.isPermitted("lightsaber:weild")) {            log.info("You may use a lightsaber ring.  Use it wisely.");        } else {            log.info("Sorry, lightsaber rings are for schwartz masters only.");        }
