Usage

From source file:xchihuo.cn.Quickstart.java

public static void main(String[] args) {

    // 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:
    Subject currentUser = SecurityUtils.getSubject();

    // Do some stuff with a Session (no need for a web or EJB container!!!)
    Session session = currentUser.getSession();
    session.setAttribute("someKey", "aValue");
    String value = (String) session.getAttribute("someKey");
    if (value.equals("aValue")) {
        log.error("______________Retrieved the correct value! [" + value + "]______");
    }// ww  w .  jav a 2 s.  co m

    // let's login the current user so we can check against roles and permissions:
    if (!currentUser.isAuthenticated()) {
        UsernamePasswordToken token = new UsernamePasswordToken("lonestarr", "vespa");
        token.setRememberMe(true);

        try {

            }
            currentUser.login(token);
            if (currentUser.isAuthenticated()) {
                log.info("---------???2");
            }
        } 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.");
    log.info(" -----------id+" + currentUser.getSession().getId() + "");
    //test a role:
    if (currentUser.hasRole("goodguy")) {
        log.info("-----------May the Schwartz be with you!");
    } else {
        log.info("-----------Hello, mere mortal.");
    }

    //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.");
    }
    currentUser.isPermitted("winnebago:drive:eagle5");
    //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();
    if (currentUser.isAuthenticated()) {
