Document how to enable validating entities with JSR-303 bean validation annotations [DATAREST-372]

Marcel Overdijk opened DATAREST-372 and commented

The Spring Data REST homepage states:

• Validate entities with JSR-303 or Spring Validator beans

However in the documentation I cannot find back how this should be enabled.
By default entities with JSR-303 annotation are not validated.

What I did to make it working is:

@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);
    }
}

I don't know if this the best way to enable JSR-303 bean validation but either way I think it's good to add to the documentation how to enable it

Affects: 2.1.2 (Dijkstra SR2)
