Automatically perform JSR 303 Bean Validation on beforeCreate/beforeSave [DATAREST-370]

Marcel Overdijk opened DATAREST-370 and commented

When using JSR 303 annotations on @Entity domain classes validation is not triggered automatically beforeCreate and beforeSave.

However itself JPA is validating after all automatically but it throws a ConstraintViolationException which is not picked up by Spring Data REST and hence causes a 500 without sending errors back to client.

This can be solved by configuring the Spring Data REST validation by using:

@Configuration
protected static class CustomRepositoryRestMvcConfiguration extends RepositoryRestMvcConfiguration {

    @Autowired
    private Validator validator;

    @Override
    protected void configureValidatingRepositoryEventListener(ValidatingRepositoryEventListener validatingListener) {
        validatingListener.addValidator("beforeCreate", validator);
        validatingListener.addValidator("beforeSave", validator);
    }
}

It would be nice to automatically do this if JSR 303 bean validation is enabled, or make this configurable?

Affects: 2.1.2 (Dijkstra SR2)
