小编Ugu*_*zel的帖子

我正在使用Spring 3和Spring Security开发一个项目.我的问题是IoC容器.当我UserDetailsService为Spring Security-3 编写自己的实现时问题就出现了.我检查了其他问题,但仍无法解决问题.

问题的定义是:

我有两个单独的类(一个是UsersController.java扩展的@Controller,ProjectUserDetailsService哪个扩展@Service),它使用一个公共对象进行自动装配.但是当对象成功自动装入时UsersController,它就null在ProjectUserDetailsService类中,尽管这个类(ProjectUserDetailsService)的对象已成功创建(我通过调试验证了这一点).

有什么建议如何解决这个问题？

这里是我的web.xml,project-servlet.xml而且project-security.xml文件和相关的类.
