[S2] Form handling life cycle with HTTP GET/POST
Hi,
I worked with Spring-MVC in my past projects and I really liked the idea
of my form actions/controllers to initialize my forms when I access them
with an HTTP GET and then process the forms with an HTTP POST. The nice
effect of this is that I have one single URL that does form
initialization as well as processing the form.
See for more details on how Spring MVC is doing it:
http://www.springframework.org/docs/api/org/springframework/web/servlet/mvc/AbstractFormController.html
Can I do something similar in Struts2?
It would be great if I could do something like this (May not make total
sense but I hope to convey my intent):
<action name="editUser" http-method="GET" method="input"> (no
validation)
<result name="success">/editUser.jsp</result>
</action>
<action name="editUser" http-method="POST" method="editUser">
(validate form and process)
<result name="input">/editUser.jsp</result>
<result name="success" type="redirect">/main.html</result>
</action>
Thanks a lot for any insights!
Regards,
Gunnar Hillert

Hello Don,
Thank you very much for your response and yes <s:submit
method="processMyForm" ... works quite well. Nevertheless, I would like to
see a more RESTful behavior implemented into Struts2 for the actions.
Don, what would be the best way to proceed from here. As a start shall I go
ahead and open a feature Request in Jira? How can I help otherwise?
Thanks -
Gunnar
PS: I look very briefly at JSR-311. IT seems to be still in very early
stages (Formed in February'07). Also, I am not sure if we would need much
more than the @HttpMethod(GET) @HttpMethod(POST) etc. annotations.

As it is, yes and no. You can use the restful2 action mapper to have
struts "guess" what the method names should be based on the URI and
the HTTP method. However, outside that, I'm guessing you are really
wanting some sort of technique that reads, say, an annotation over a
method that says that this method should only be called when the HTTP
method is, say, "PUT". Right now, there is no such feature, however,
I'm very interested in supporting something like that, particularly if
it uses the recent Restful JSR annotations the the JCP is working on.

Re: Re: [S2] Form handling life cycle with HTTP GET/POST
Posted by Gunnar Hillert <gu...@hillert.com>.
Hi,
Thanks for your quick response. I will take a look at this. But my
question is: can I configure my actions in a way/somehow that they
execute different methods when called through different HTTP methods
e.g. GET, POST maybe even DELETE.
Call the action’s input method if it is a GET, call the execute method
if it is a POST. (Maybe you can even call it 'restful form handling' :-)
Anyway, I have to look into your suggestion as well -
Thanks again!
Cheers,
Gunnar

Yep, that should work almost exactly as you describe, although what I
would do is use a single action definition. You can specify exactly
what method to call either in the URL (via the action!method.action
syntax) or in your action definition. Say you make the default case
be "input" in your action definition, but then when submitting the
form, set the "method" attribute on the submit button to ensure that
the submitted form calls the editUser method. Incidentally, the
validation interceptor is pre-configured to not validate when the
"input" method is called, but tries to validate anything else.
