How to I get Spring-Data-MongoDB to validate my objects?

Question

I have a very simple Spring Boot application that uses Spring-Data-Mongodb

All I want to do is set a JSR-303 validation rule that says the object I\'m saving must ha

Answer 1

First make sure that you have JSR-303 validator on classpath, for example:

    org.hibernate
    hibernate-validator
    4.2.0.Final

If you use Java config, the way to go is to create 2 beans:

@Bean
public ValidatingMongoEventListener validatingMongoEventListener() {
    return new ValidatingMongoEventListener(validator());
}

@Bean
public LocalValidatorFactoryBean validator() {
    return new LocalValidatorFactoryBean();
}

Voilà! Validation is working now.
