Shiro最佳实践(七)Spring集成与EhCache

2019-08-04 18:01:16 阅读:()

就笔者现在而言,深入与Spring集成才是最终的方向,同时将常用的一系列授权相关功能给做到期望的程度,所以在于spring集成时考虑了实现以下功能点:

1、登录/退出;

     登录支持自定义登录/退出,验证码支持(本例中验证码只是模拟,并未使用图片),记住我,登录失败错误提示等。

2、权限控制;

     权限功能模拟从数据库中获取,权限控制及未授权页面显示;

3、用户授权缓存;

     集成EhCache实现用户授权信息缓存;

自定义认证Realm

        }
        SimpleAuthenticationInfo auth =
