使用AutowiringRequestProcessor整合struts和spring遇到的问题

Question

如题，小弟今天遇到了一个AutowiringRequestProcessor不能自动完成注入service实例的问题，得到的service是空的，不管使用byName和byType都不行。如果使用ApplicationContext ctx = WebApplicationContextUtils .getRequiredWebApplicationContext(request.getSession()
  .getServletContext());
 pUserExtService=(IPUserExtService)ctx.getBean("pUserExtService");获得service,以下程序能正常运行。现帖出源码，希望各位能帮忙解决，谢谢！

Answer 1

应该作为context-param存在，而不是ActionServlet的init-param
