spring-security3.2.5实现中国式安全管理(转)

最近公司要做开发平台，对安全要求比较高；SPRING SECURTIY框架刚好对所有安全问题都有涉及，框架的作者最近还做了spring-session项目实现分布式会话管理，还有他的另一个开源项目spring-security-oauth2。           关于spring-security的配置方法，网上有非常多的介绍，大都是基于XML配置，配置项目非常多，阅读和扩展都不方便。其实spring-security也有基于java的配置方式，今天就讲讲如何通过java配置方式，扩展spring-security实现权限配置全部从表中读取。 
    直接上代码： 
application.properties配置文件

Java代码  

1. privilesByUsernameQuery= select  authority from user_authorities  where username = ?
2. allUrlAuthoritiesQuery=SELECT authority_id , url   FROM Url_Authorities
