What is the effect of Params Interceptor?
I read this tutorial<http://www.tutorialspoint.com/struts_2/struts_interceptors.htm>,
but I don't understand what Params Interceptor is used for?
Example:
<action name="someAction" class="com.examples.SomeAction">
<interceptor-ref name="params"/>
<result name="success">result.jsp</result>
</action>
If the timer interceptor being used, we will see this kind of message:
*INFO: Executed action [//hello!execute] took 109 ms.*
But what about params interceptor? What would happened if it's used? I
tried and don't see anything.

Yes, it's pointless :-)

Oh, so that means there is no point to define the params interceptor in
Action mapping (as seen below) because it's included in struts-default.xml?
<action name="someAction" class="com.examples.SomeAction">
<interceptor-ref name="params"/>
<result name="success">result.jsp</result>
</action>

Well, not implicitly, but by default. It is included in the struts-default
stack.

So is that means struts 2 is using params interceptor implicitly?

Re: What is the effect of Params Interceptor?
Request parameters refers to the data that is supplied with the GET query
string or POST body (typically from form parameters). And the Params
Interceptor takes those parameters and calls the corresponding mutators on
the Action.

Request parameters refers to the data that is supplied with the GET query
string or POST body (typically from form parameters). And the Params
Interceptor takes those parameters and calls the corresponding mutators on
the Action.

Re: What is the effect of Params Interceptor?

Hi,
Is Request Parameters has same meaning with the Action's property field
(the one with getter/setter) ?
For example:
http://www.tutorialspoint.com/struts_2/struts_actions.htm
HelloWorldAction has "name" property. Then in index.jsp, there is a form
that has "name" textfield data that will be sent to the HelloWorldAction if
the submit button is clicked. So, in this case, could the "name" textfield
data can be called as a Request Parameter if it is being submitted to
the HelloWorldAction?

Re: What is the effect of Params Interceptor?

Params interceptor is used in Injecting the Request Parameters into the
Action, either individually or (using the ParameterAware interface) all at
once.
