Does spring-data-neo4j have a beforeSave method?

Question

How can I execute some code just before an entity is saved?

@NodeEntity
public class Person {

    @Transient
    String password
    String passwordHash

    public void beforeSave() { // I made this method name up.
        if (password != null && !password.isEmpty()) {
            passwordHash = AuthenticationService.encodePassword(email, password);
            password = null;
        }
    }
}

Do I need to use AspectJ or is there a simpler way using an annotation?

I've added the following dependencies:

compile("org.springframework.data:spring-data-neo4j:3.3.0.RELEASE")
compile("org.springframework.data:spring-data-neo4j-rest:3.3.0.RELEASE")

In SDN3, you have BeforeSave ApplicationEvents like in the rest of the Spring Data projects.
