Spring 自动连线bean-eclipse调试为空

我遇到了一个可以让我学习SpringMVC的项目。我希望会话bean（用户）自动连接到控制器（ChatController）。下面的代码示例似乎就是这样做的，但是当我设置断点时，我注意到User的所有属性都保持为null。但是，println会按预期打印第一个名称

知道我做错了什么吗

@Controller
public class ChatController {

    @Autowired
    private User user;

    @RequestMapping(value="/chat")
    public ModelAndView start()
    {
        System.out.println("pre" + user.getFirstName());
        user.setFirstName(user.getFirstName() + " foo");
        System.out.println("post"+user.getFirstName());


        return new ModelAndView("/WEB-INF/views/error.jsp");
    }   

    public User getUser() {
        return user;
    }

    public void setUser(User user) {
        this.user = user;
    }

}

通过进一步阅读CGLIB，我了解到这是代理使用该库的正常行为

代理的属性将显示

null

。代理只是到实际类的路由，它不保存类本身的值

探索代理的属性，您将发现填充了其属性的对象；i、 e.它可能会建议，探索该问题并找到

targetSource

，探索该问题并找到target。
