@RepositoryEventHandler is not getting invoked

I have created a simple repository for my app users:

@RepositoryRestResource(path = "users")
public interface AppUserRepository extends JpaRepository<AppUserModel, Long> {

    List<AppUserModel> findByUsername(@Param("username") String username);

}

However, I need to take care of password encryption before a new user gets inserted. For this I implemented a @RepositoryEventHandler:

@RepositoryEventHandler(AppUserModel.class)
public class AppUserService {

    @HandleBeforeSave
    public void handleProfileSave(AppUserModel appUserModel) {
        System.out.println("Before save ..");
    }

    @HandleBeforeCreate
    public void register(AppUserModel appUserModel) {
        System.out.println("Before create ..");
    }

}

The problem is that none of those two event handlers are getting executed. As a result AppUserModel is tried to be persisted but fails because no salt (for the password) has been generated and set - that's how I can tell that the JpaRepository<AppUserModel, Long> is working so far.

{
"cause": {
    "cause": {
        "cause": null,
            "message": "ERROR: null value in column "password_salt" violates not-null constraint Detail: Failing row contains (26, 2017-11-18 21:21:47.534, 2017-11-18 21:21:47.534, f, asd, null, [email protected])."
        },
    "message": "could not execute statement"
    },
    "message": "could not execute statement; SQL [n/a]; constraint [password_salt]; nested exception is org.hibernate.exception.ConstraintViolationException: could not execute statement"
}

Another way could be providing the bean from within another configuration class:

@Configuration
public class RepositoryConfiguration {

    @Bean
    AppUserEventHandler appUserService() {
        return new AppUserEventHandler();
    }
}

However, I prefer the solution provided by @varren.

It looks to me that you just need to create AppUserService bean. The easiest option would be to annotate it with @Component

@Component
@RepositoryEventHandler(AppUserModel.class)
public class AppUserService {
    //...
}
