 1 //擷取值棧 2         Map cont= this.getStack().getContext();    3         StrutsRequestWrapper req=(StrutsRequestWrapper)cont.get(StrutsStatics.HTTP_REQUEST);   4         //擷取請求action的地址 5         String url=(String)req.getAttribute("javax.servlet.forward.request_uri"); 6         System.out.println("PageComponent.start()"+url); 7          8         //擷取的標籤所在jsp頁面的全路徑 9         StringBuffer stringBuffer=req.getRequestURL();//http://localhost:8080/Struts2HibernateSpring/list.jsp10         System.out.println("PageComponent.start()"+stringBuffer.toString());11         12         //擷取的是請求背景地址，其中的參數的值13         Object object=req.getAttribute("pageNo");14         System.out.println("PageComponent.start()");15         //key--->value16         //javax.servlet.forward.query_string-->(擷取請求參數字串)pageNo=1&seachName=%E5%B0%9A%E6%99%93%E9%A3%9E17         //javax.servlet.forward.request_uri-->(擷取請求路徑到方法名)/Struts2HibernateSpring/StudentAction!queryStudent18         //javax.servlet.forward.context_path-->（ 擷取項目名）/Struts2HibernateSpring19         //javax.servlet.forward.servlet_path--> (擷取請求的action名字+method名字)/Struts2HibernateSpring20         //struts.request_uri --->(擷取請求路徑到方法名)/Struts2HibernateSpring/StudentAction!queryStudent21         //struts.view_uri -->(擷取struts請求返回的jsp的路徑)/list.jsp22         //__cleanup_recursion_counter---> 123         //characterEncodingFilter.FILTERED--> true24         //struts.actionMapping--->ActionMapping{name=‘StudentAction‘, namespace=‘/‘, method=‘queryStudent‘, extension=‘null‘, params=null, result=null}25         //org.springframework.web.context.request.async.WebAsyncManager.WEB_ASYNC_MANAGER--->[email protected]f892d26         //struts.valueStack--->[email protected]27         Enumeration<String> pd=req.getAttributeNames();28         while(pd.hasMoreElements()){29             String nameString=pd.nextElement();30             Object object2=req.getAttribute(nameString);31             System.out.println("PageComponent.start()"+object2);32         }33
