Scope 'request' is not active for the current thread

Unable to instantiate Action, getUserAction,  defined for 'getUser' in namespace '/'Error creating bean with name 'getUserAction': Scope 'request' is not

 active for the current thread; consider defining a scoped proxy for this bean if you intend to refer to it from a singleton;

nested exception is java.lang.IllegalStateException: No thread-bound request found:

Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread?

If you are actually operating within a web request and still receive this message,

your code is probably running outside of DispatcherServlet/DispatcherPortlet:

In this case, use RequestContextListener or RequestContextFilter to expose the current request.

将request改为property，不知道为什么会这样

在网上看到有人这样回答

Scope 'request' is not active for the current thread这句话中说明在某个线程上试图调用scope为request的bean，但是这个bean中能被在http请求线程中实例化，

简单地说就是：在客户请求的时候才可以被实例化。而我的问题是在服务器启动的时候要实例化，所以有"Scope 'request' is not active for the current thread"

这一句的出现。在项目中如果有些bean实现了spring中的某些接口（如：SessionAware,RequestAware或BeanPostProcessor等等),就会在服务器启动的时候自动创建代理

(proxy)，这时如果该bean的scope为request、session...这些web作用域的时候就会出现

consider defining a scoped proxy for this bean if you intend to refer to it from a singleton这句话。

我的'UserService'这个bean就是间接实现了BeanPostProcessor这个接口，所以一直抛出上面的异常。
