Access login page data after user is authenticated

[zhangj5]

Hi all,

I am very new to Spring, and I will do my best to explain my problem.

I have a login.jsp to perform OpenID authentication, and there are also some other values contained within the login.jsp, for example a hidden input

<pre><input type="hidden" name="Language" value="English"></pre>

When the authentication succeeded, I want to be able to access the values from the login.jsp, such as the "Language" value is "English". So the flow would be
1. Save the value in the hidden form in somewhere.
2. OpenID authentication.
3. Access the value of the hidden form in somewhere.
So, my problem is where and how can I save those values.


Thanks.

Spring Security supports localization through Spring's LocaleContextHolder, but managing that Locale is outside of what Spring Security supports. If you want to manage the locale, use the MVC framework of your choice. If you are using Spring MVC, see the using locales from the Spring MVC documentation.

Thanks, rwinch. I learned another powerful Spring feature.
However, maybe my example in the first post confused you. The name and value of the hidden input are not just "Language" and "English", it can be something like

<input type="hidden" name="name_1" value="value_1">
<input type="hidden" name="name_2" value="value_2">

And there can be up to 5 of such inputs.
So i thought if I can use an object to store those hidden inputs, like

public class MyHiddenObject{
          private String value_1;
          private String value_2;
          .........
          private String value_5;
          //getter and setters
         ........
}

Then, I can read the hidden inputs at some stages, store them into MyHiddenObject. When the OpenID authentication is returned, I can read the values from MyHiddenObject.
The steps would be
1. User click Google image to authenticate using OpenID.
2. Store hidden form values into MyHiddenObject using setters.
3. Store MyHiddenObject into somewhere.
3. OpenID authentication.
4. Retrieve MyHiddenObject from somewhere.
5. Read MyHiddenObject fields using getters.

Any idea? Thanks

If the credentials are for authentication you might have a look at the faq http://static.springsource.org/sprin...a-login-fields You could store the extra fields in Session.

Thanks again. I will try OpenIDAuthenticationFilter as I am using OpenID authentication.
The only thing that I am afraid of using session is the values of the input fields may contain texts larger than string like "a company name" or "a phone number", it could be the HTML source code of another web page, or a text document (less than 1000 sentences in average). Will this cause negative effects on the performance, such as speed.

Out of curiosity what are you going to put in the fields and what do you intend to do with the values? If you think the values are too large you can store an idea in session and store the fields in a database or cache.

If i save the value in the session, say there are two instances of the login page opened by a user, I think the extra fields from these two instances will overwrite each other.
