Hello,

I have an object which is annotated with @NotEmpty, @Email and other validators. I would like to validate the state of the object right after its construction. Is there a way I can do this without saving the object in the database?

Thanks

Sure, just get hold of a ValidatorFactory and create your own Validator instance, then call Validator.validate. How you get hold of the ValidatorFactory depends on the environment you are running in. You can always just boostrap Bean Validation directly (check the Hibernate Validator online documentation) or you might get hold of the ValidatorFactory provided by your container (eg via JNDI) or dependency injection framework.

Thanks, that's exactly what I was looking for.

I was able to get this to work using

However, I wasn't able to configure validationFactory using Spring. The following did not work because ValidatorFactoryImpl does not have no-arg constructor.
<bean id="validatorFactory" class="org.hibernate.validator.engine.ValidatorFactoryImpl"/>

Which validation factory implementation should I inject?

Thanks

Depending on which Spring version you are using you might be able to use the bean provided by Spring. I think there is a LocalValidatorFactoryBean, but I am not sure.

Otherwise this might help - HV and Spring
