java - Spring SimpleFormController onSubmit request parameters -

-

I am using SimpleFormController in my application to handle form submisions. One thing that I am missing is the request object which has passed onSubmit (request, response ..) is different from the initial request object which is received by formBackingObject (..) Happens . Obviously because this is the new request from the web once again.

I want to use the same parameters from the requested object in submit (..) formBackingObject (..) .

It may be possible that I can collect them from the hidden areas by jossi, but I am trying to get some elegant perspectives.

Is there any way to do this?

Edit:

I'm overriding 

  formBackingObject (HTTPSArlet Request) `

and

<<>

Methods in my class.

> Formbacking object (..) will be called for intent view and I will have some variables from the request object if the user forms If I am called onsmember (..) , then I have another request that is different from the object which I received in formbackingObject (..) .

What I am asking, is there any way to catch the initial 'request' parameter (like request.getParameter () ), so that I can use them You can send onsite (..) to send them back & amp; Through hidden areas? '

formBackingObject () The method is being called when the user starts the initial form Requests for the scene. This is a completely different HTTP request when a user submits the form on which the onsmitt () method is called.

If you want to save the state with the first HTTP request, it is available in another HTTP request, your best option is to save it in an HTTP session.

Example: In your formBackingObject () method: 

  http session session = request.getSession (); Session.setAttribute ("param1", request.getParameter ("param1")); Session.setAttribute ("Ultimate 2", request.getParameter ("param2"));

and your onSubmit () method: 

  http session session = request.getSession (); String Param 1 = (string) session.getAttribute ("param1"); String param2 = (string) session.getAttribute ("param2");

oracle - The fastest way to check if some records in a database table? -

-
I have a big table to work with. I have to see that there are some records whose parent_id is equal to my passing value. Currently I do this by implementing "my_table using select count (*) where parent_id =: id"; If the result> 0, it means that they exist. Because this is a very large table, and I do not care what the actual number of records present, I just want to know if it exists, so I think count (*) Bit is disabled. How do I apply this requirement most quickly? I'm using Oracle 10. # Tips for Hibernation & amp; Tricks It suggests writing in such a way: Integer number = (integer) session .createQuery ("Select Count (*) to ...."). UniqueResult (); I do not know what is the magic of the unique rule? Why does it fast? To compare, select "1 from mytable where parent_id = passId and rowrum", which is more efficient? If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
