解压之后在samples|quickstart|src|main下拷贝相应的文件到shiro-1工程中哦!

说明: Quickstart是类文件; log4j.properties是日志配置文件; shiro.ini存放的账户和角色.

shiro.ini

[users]
    # user 'root' with password 'secret' and the 'admin' role
    # root=secret 分别表示账号和密码，admin表示逗号前边的账号拥有 admin 这个角色。
    root = secret, admin
    # user 'guest' with the password 'guest' and the 'guest' role
    guest = guest, guest
    # user 'presidentskroob' with password '12345' ("That's the same combination on
    # my luggage!!!" ;)), and role 'president'
    presidentskroob = 12345, president
    # user 'darkhelmet' with password 'ludicrousspeed' and roles 'darklord' and 'schwartz'
    darkhelmet = ludicrousspeed, darklord, schwartz
    # user 'lonestarr' with password 'vespa' and roles 'goodguy' and 'schwartz'
    lonestarr = vespa, goodguy, schwartz
    
    [roles]
    # 'admin' role has all permissions, indicated by the wildcard '*'
    # admin 表示角色名称，* 表示这个角色拥有所有权限
    admin = *
    # The 'schwartz' role can do anything (*) with any lightsaber:
    schwartz = lightsaber:*
    # The 'goodguy' role is allowed to 'drive' (action) the winnebago (type) with
    # license plate 'eagle5' (instance specific id)
    goodguy = winnebago:drive:eagle5

            // 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):
    		//1>获得工厂对象

            // 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

运行效果如下:

(1)账号和密码正确登录
