@Mathias it seems the following is enough for jsr 303 annotations to be checked and for it to auto return a http code of 400 with nice messages (I dont even need BeforeCreateCompanyValidator or BeforeSaveCompanyValidator classes):

@Configuration
public class RestValidationConfiguration extends RepositoryRestConfigurerAdapter{

@Bean
@Primary
/**
 * Create a validator to use in bean validation - primary to be able to autowire without qualifier
 */
Validator validator() {
    return new LocalValidatorFactoryBean();
}


@Override
public void configureValidatingRepositoryEventListener(ValidatingRepositoryEventListener validatingListener) {
    Validator validator = validator();
    //bean validation always before save and create
    validatingListener.addValidator("beforeCreate", validator);
    validatingListener.addValidator("beforeSave", validator);
}

}

400 response:

{
    "errors": [{
        "entity": "Company",
        "message": "may not be null",
        "invalidValue": "null",
        "property": "name"
    }, {
        "entity": "Company",
        "message": "may not be null",
        "invalidValue": "null",
        "property": "address"
    }]
}
