Spring Singleton的陷阱

Acegi SecurityContextHolder 默认采用 ThreadLocal 存储 authentication 对象, 每次使用当然都要重新获取,

正确的用法应该是这样的
public class SomeServece extends BaseService implements SomeInterFace    
{  
      
      
    public someMethod()  
    {  
       int userID = super.getUserInfo().getUserID();  
       String userName = super.getUserInfo().getUserName();  
       //bla bla do something user userID and userNaem  
    }  
}
