Hello in case of microservices we have to put annotation on DTOS or Entity?

[alexdev__]

Thanks my bro... You have earned the sky

[eleafarpan]

Thank you so much . I just have a question. Can it work for more than one relationship, that is, if this same departments table were related to the Professors table, can you use the @JsonBackReference and @JsonManagedReferences annotations for these tables?

[emmanlife]

does it work on files that have multiple one to many and many to one relationship?

[Aakashkumar-pcxs]

Hey is there any way to do this without any extra annotation, because in my previous company my manager use to do bi-directional mapping with any extra annotation, and all data was coming perfectly.

LOMBOK USERS: If you're scratching your head because none of this works, it's because of Lombok! It's generating .toString, .equals, and .hashCode methods in the Student class that calls these same methods in the Department class, which in turn calls the Student methods and on and on!

The solution is to put the following annotations above the department property in Student class:

@ToString.Exclude
@EqualsAndHashCode.Exclude

That will omit the company property from these methods, breaking the recursion loop. Hope this helps!
