First of all, it is a coincidence that JSF learns the same. To reprint, please help yourself, if there is a mistake, please forgive me!
Encountered the same problem as STRUTS2---how to get the value passed over
Because JSF, like STRUTS2, can directly use a bin as an action-handling business logic without inheriting the framework. So we can't just introduce it in the parameters.
Get the Request object in Struts2
HttpServletRequest request = Servletactioncontext.getrequest ();
Get Sessioon object in struts
HttpSession session = Request.getsession ();
JSF to get the request object to take value
String Name= (String) facescontext.getcurrentinstance (). Getexternalcontext (). Getrequestparametermap (). Get ("name") ;
Get Sessioon object in JSF
Map Session=context.getexternalcontext (). Getsessionmap ();
Note that the JSF is all map types. This article links http://www.cxybl.com/html/wyzz/JavaScript_Ajax/20130724/39297.html
