[@sagarthapliyal5661]

Wow bro lovely, I was running over the internet all over but did not find the solution.... Amazing bro, thankk you so much

[@felipeavila1883]

I'm Brazilian, you helped me a lot, thank you

[@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?

[@juanpablosuarezsoler5068]

You're the best, thanks so much! Subscribed!

Very good stuff! Congrats!

Thanks so much! great video

Glad it was helpful!

[@himanshunegi8108]

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

[@heumn1899]

Спасибо

[@MrFahimansari]

Thanks so much. The video is really informational. I have a doubt, will this apply for one to one bidirectional relationships also

[@KindsonTheTechPro]

It works for bi-relationships as well

[@MrFahimansari]

@@KindsonTheTechPro hey I wanted to know if it works for one to one mapping also?

[@wilsonho4577]

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

[@KindsonTheTechPro]

This is an interesting question! I'll check

[@amarnathgreentech5466]

i am getting only id values instead of complete object please help me..

[@KindsonTheTechPro]

Check your getters and setters. Also check you have two constructors. Let me know the outcome

[@Andrescudero1]

Thanks so much! great video but how could you solve this problem with many to many relation? I'd appreciate very much your answer :)

[@adels6472]

the solution above stops the recursive loop error.... but with many-to-many, it gives a nested feedback ... which DOSE solve the problem but provides another :)

[@capitanrdc99]

Amazing job!!!

[@Aakashkumar-pc3xs]

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.

[@vrxtremesxg3299]

write your custom methods for saving

[@genos9926]

Thanks for the solution.

[@KindsonTheTechPro]

Happy to help😊

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!
