Hello, I have a problem with hibernate validator annotations. How do I internationalize error messages? Would have a complete example that explains the whole procedure?
Thanks in advance for your cooperation.
Mario

Hi,

you just have to add a set internationalized ValidationMessages property files to your classpath. Hibernate Validator ships with some internationalized properties files which you can see here http://fisheye.jboss.org/browse/Hiberna ... /validator

Obviously, these files live under org.hibernate.validator. Your own message bundles have to be placed into the root context of your jar file.

I'm working with an application in spring.
As the application to handle errors, invokes the default properties file, how do I invoke the properties file that interests me?

I want to clarify one thing.
I added the properties file in Italian and if the browser language is Italian, I receive messages properly. If you set your browser in English, always call the properties file in Italian. How do I call the file in question?
We will send you the code that I wrote.
Thank you for availability

public void afterPropertiesSet() throws Exception {
Configuration<?> configuration = Validation.byDefaultProvider().configure();
ValidatorFactory factory = configuration.messageInterpolator(new ContextualMessageInterpolatorLocal(configuration.getDefaultMessageInterpolator(),LocaleContextHolder.getLocale()))
.buildValidatorFactory();
validator = factory.getValidator();
}

ContextualMessageInterpolatorLocal;

public class ContextualMessageInterpolatorLocal implements javax.validation.MessageInterpolator{
private final MessageInterpolator delegate;
private final Locale defaultLocale;


public ContextualMessageInterpolatorLocal(MessageInterpolator delegate, Locale locale) {
this.delegate = delegate;
this.defaultLocale = locale;
}


@Override
public String interpolate(String message, Context context) {
return this.delegate.interpolate(message, context);



@Override
public String interpolate(String message, Context context, Locale locale) {
return this.delegate.interpolate(message, context, this.defaultLocale);
}
}

Using a custom MessageInterpolator is the right ways forward. You have to make sure though that all interpolation calls will use the right Locale.



should also delegate to the default interpolator using the Locale you set up.



I am not sure where and how this code is run, but you should not rebuild the factory all the time. In a webapp for example add the browser Local to a ThreadLocal and let my custom message interpolator extract it from there before delegating to the default interpolator. Something like this.

Btw, in your case the chosen properties file is probably always the Italian one, because your user Locale is Italian.

Hello
thank you for your information. The application still does not work. My problem is that my defaultMessageInterpolator is always Italian and do not know how to call another. How do I? I send you the code.

Configuration<?> configuration = Validation.byDefaultProvider().configure();
Locale locale = LocaleContextHolder.getLocale();
logger.info("Llocale: '" + locale );
MessageInterpolator interpolator = new ContextualMessageInterpolatorLocal( configuration.getDefaultMessageInterpolator(),locale);
ValidatorFactory validatorFactory = configuration.messageInterpolator(interpolator).buildValidatorFactory();
alidator = validatorFactory.usingContext().messageInterpolator(interpolator).getValidator();

Thanks in advance.

My problem is that I want to build a validatorfactory that is not the default

I think your code look ok. You already have a custom inerpolator ContextualMessageInterpolatorLocal which takes care of selecting the right Locale. At least that's what the code suggests. The default message interpolator for Hibernate Validator is ResourceBundleMessageInterpolator which should always honor the specified Locale. Only if the specified Local is cannot be found it will fall back to the default resource bundle.

Have you tried debuggin your problem. What happens in ResourceBundleMessageInterpolator? Do you have the right resource bundles and can they be found. You can turn on logging. Set the category for org.hibernate.validator.engine.ResourceBundleMessageInterpolator[ to debug or trace. The interpolator should print out some information about the loaded resource bundles.

Hello
I solved the problem in this way. I write the code. Do you think I chose the best solution or you have another solution?
Thank you for your attention and for your help.

The code is as follows:

Locale locale = LocaleContextHolder.getLocale();
logger.info("Llocale: '" + locale );
ResourceBundle bundle = ResourceBundle.getBundle("org/hibernate/validator/ValidationMessages", locale);
Locale.setDefault(LocaleContextHolder.getLocale());
bundle = ResourceBundle.getBundle("org/hibernate/validator/ValidationMessages");
MessageInterpolator interpolator = new ResourceBundleMessageInterpolator(bundle);
ValidatorFactory validatorFactory = Validation.buildDefaultValidatorFactory();
validator = validatorFactory.usingContext().messageInterpolator(interpolator).getValidator();

Bye, Mario.

Hi,

no, I don't think this is a good solution. It is not a good idea to call Locale.setDefault(). The default Locale applies fort the whole JVM which is probably not what you want in a multi language web application.
I still don't know where and how the code you are showing is executed, but my guess is you will run into trouble at some stage.

--Hardy

Hi,

the code I sent you yesterday I has been used in a project with "Spring". I do not know if it can help you. I can not find another solution from the one that I sent you.

Bye, Mario

have you another solution to solve the problem without invoking the method Locale.setDefault ()?

Bye, Mario

Hi.
I think this is the correct code to bypass the defaultLocale from ResourceBundleMessageInterpolator.
(this is not tested yet).
The point is that you should always call interpolate on delegate with the locale parameter, to avoid the default implementation to access its own defaultLocal.
Note that I haven't tested this yet.



the rest of your code seems correct to me.

i think i faced the same problem and found out its cause. See http://opensource.atlassian.com/projects/hibernate/browse/HV-306 for explanation and TestCase.

Hello,

What steps are necessary for outputing messages in differnet locales depending on the users session?

ResouceBundleMessageInterpolator chooses the english version all the time, why doesnt it have a constructor like
RBMI(ResourceBundle r, Locale l) and then load the resourcebundle by the locale specified by l?

I have tested the ResouceBundleMessageInterpolator2 and it does not work, still the messages are in the default, english.

Thank you
