articleListAction.action? ID = $ {ID}


articleListAction declare an ID variable , and provides set / get methods
------ For reference only --------------------- ------------------
the result of the type attribute to redirect, redirect
------ For reference only ------ ---------------------------------
then how to pass parameters?
------ For reference only -------------------------------------- -
articleListAction & xxx = yyy
------ For reference only --- ------------------------------------
that how to get inside this parameter in the ACTION ?
------ For reference only -------------------------------------- -
inside struts.xml configuration parameter is not passed , but in the concrete inside the given url

example you from a web component , such as a jsp, servlet even other struts Action class inside, can provide this parameter:

to jsp example: In the js inside :
document.forms [0]. action = "postArticleAction.do? id =" + id value of your
then submit

in your
com.bbs.showAction class inside :
By String id = request.getParameter ("id"); take this parameter
------ For reference only ------------- --------------------------
chain types can be defined inside
------ For reference only ---------------------------------------





------ For reference only ----------------------------- ----------
action jump you can put request.setAttruct ("id", xx) , so in articleListAction directly get in the way ,
they request the same directly to the articleListAction is taken on it
------ For reference only ------------------- --------------------
type = "chain" can also be removed
------ For reference only - -------------------------------------
<

  <action name="postArticleAction" class="com.bbs.showAction" method="postArticle">
  <result name="success" type="chain">articleListAction.action?id=${id}</result>
  </action>
  

------ For reference only ---------------------------------- -----
