[Springframework-rcp-dev] Validation... Which framework?

[Benoit X. <bx...@ob...>]

Hi

 

I thought I’d ask the community…  there are quite a few validation
frameworks out there, notably, amongst the more modern ones:

-          Spring Validation

-          Spring Rich Client Validation

-          Hibernate Validation

 

Given a scenario of a 3-tier application where serialized objects are sent
back-and-forth between a Swing application and an RMI server, and then
stored in DB via Hibernate. 

Which framework do you think would be most appropriate to use to ensure a
good GUI feedback prior to submitting an object but also enforcing solid
validation on the server-side? (the server also interacts with JMS so
server-side validation is really important).

 

At the moment, we’re using a mixture of Spring Rich Client Validation (hand
coded using the Rules) and some internal mechanism on the server side.

 

I’d like to be able to have ONE place where I put the validation rules… it
seems that the Hibernate Validation may be the most obvious choice there…
and I believe that there is some code to integrate it in Spring RC? Where
could I find some information on how to use it and does integrate in the
same way as the Spring Rich Client Rule for error messages/display icons
etc?

 

What is your experience with any of these frameworks?

A quick review on this subject would be a GREAT blog posting…

 

Thanks a lot

Best regards,

 

Benoit

We're using Hibernate validator in combination with RCP.
There are 2 classes in spring-richclient which help with that:
- the RulesFactory thingy, so only need to duplicate the rules on the 
view side for the @AssertTrue's, but not for @NotNull, @Length etc.
- the hibernate validator exception handler, in case the back-end does 
extra validation (or a business method creates invalid objects), so 
those get reported nicely.

Both are in the jdk5 package I believe.

With kind regards,

Re: [Springframework-rcp-dev] Validation... Which framework?

[Benoit X. <bx...@ob...>]

Hi Geoffrey,

Thanks a lot for your reply. I also got a reply from the forum, so I start
to get a better idea...
(http://forum.springframework.org/showthread.php?p=178812)

I have noticed the CompositeRichValidator which mentions the Hibernate
validation mechanism.

Would you mind showing a quick example of how to bind the lot? Say a very
simple @NotNull. Which XML setting is required? How to write the
CompositeRichValidator?

Where do you put this new CompositeRichValidator? do you extend
DefaultRulesSource? or does it need to be added manually everywhere a
FormModel is created for that class?

The javadoc seems to imply this:
Code:
 HibernateRulesValidator hibernateRulesValidator = new
HibernateRulesValidator(getFormModel(), SomeClass.class);
 hibernateRulesValidator.addIgnoredHibernateProperty("ignoredProperty");
 RulesValidator rulesValidator = new RulesValidator(getFormModel(),
myRulesSource);
 getFormModel().setValidator(new CompositeRichValidator(rulesValidator,
hibernateRulesValidator));

Is there a way to register all the classes that should be subject to
Hibernate validation in one place (similar to extending
DefaultRuleSource)... None of our code calls the createFormModel with a
ruleSource, so it seems that the defaultSource is used, which we have
extended to cover all our classes via 'addRules', eg:
public class SafeMarginValidationRulesSource extends DefaultRulesSource {
    public SafeMarginValidationRulesSource() {
        super();
        addRules(createReconciliationRunListCriteriaRules());
    }
...
    private Rules createReconciliationRunListCriteriaRules() {
        return new Rules(ReconciliationRunListView.Criteria.class) {
            @Override
            protected void initRules() {
                add("date", required());
            }
        };
    }
}

I've seen the HibernateValidatorDialogExceptionHandler class but it would be
great to see a posting with details of how to wire it (do you pickup the
exception thrown by the Hibernate validator?)...

many thanks

Benoit
