is this struts 1.x form bean in session scope or request scope?
I have been searching for a concrete answer for this, as much of google returns a lot of very old posts. Is this greetingActionForm
in the request scope, or in the session scope? Is there any location besides the action
and form-bean
declaration to determine a form's scope?
<action-mappings>
<action path="/hello/my/oldfriend"
type="com.imFine.HowAreYouAction"
name="greetingActionForm"
validate="tru开发者_开发知识库e"
input="/the/front/door">
<forward name="success" path="/go/get/drinks.do" />
</action>
</action-mappings>
<form-beans>
<form-bean name="greetingActionForm" type="com.forms.GreetingActionForm"/>
</form-beans>
If unspecified, by default an ActionForm will have scope session
.
The scope of an ActionForm is specified on the <action>
configuration as attribute scope
. You can find this in the Struts DTD:
The "action" element describes an ActionMapping object that is to be used
to process a request for a specific module-relative URI. The following
attributes are defined:
.....
.....
scope The context ("request" or "session") that is used to
access our ActionForm bean, if any. Optional if "name" is
specified, else not valid. [session]
.....
.....
This value is initialized in the org.apache.struts.config.ActionConfig class which represents the configuration information of an element from a Struts module configuration file:
/**
* <p> Identifier of the scope ("request" or "session") within which our
* form bean is accessed, if any. </p>
*/
protected String scope = "session";
