Entity Mapping | @OneToOne, @OneToMany, @JoinColumn| Spring Data JPA | Spring Boot | Dev2Prod Coding 

I like the fact that you have already created the classes(entity, controllers) before you record the video, which makes the video simple and short

Just because of your perfect solution and exact explanation instead of keeping it long you made it short. I am subscribing your channel. Good Efforts thank you :)

Great Video...Helped me a lot..Thanks

I might sound stupid but I found it interesting that f.k @OneToOne private Address address, Employee class has a attribute of address which data type is Address, and it actually stores int value which is addressID? and by setting cascade.all, when we send request payload for saving emps, it will affect Address class and save address info on Address table. And the fk column in emp table will show just int value(AddrID). I learned a lot. and I hope I understand correctly. Thanks!

nice video..cleared all my doubts.thank you

Thank you very much

wow

Thank you bro

Hi bro .. how to configure my slq or post man in application properties.. will u please solve that

thank you

How to implement it with Angular though?

Great Explanation bro...but one error is occuring actually when we run many to one first time it will save the data but if we add another member of same addresse it will update the data...that means fk_emp_id 1 will replace by 2 so...what to do plz help me

Push the file to git

Bro, in address class , during 1-1 7:59 before and after using @OneToOne(mppedby="address") the output/table structure of address is same na, then can u tell me what is the use of that annotation

How foreign key is created in address table? You mentioned address reference inside Employee entity right! then how foreign key is created inside address table?

Sex bro Sex, even I couldn't understand this from Java Brains, Be Coder, and Code With Durgesh. You made a flawless victory...

your video really very helpfull for me thankyou

if i duplicate my request in postman, so duplicate my entities, that not shoul be happen, because then i have duplicate employees and addresses, how do yo stop this behavior, you put some logical in your service?(sorry for my english)

brother podrias hacer uno con orden bbidireccional

I want to ask one q : when you used unidirectional you have not written one to one in address class and when you showed bidirectional then you write one-to-one in address class but there was no difference in output that you showed so why we have to write one-to-one in address class when there is no difference in output?

Where is properties file

Why 90% od tutorials are low quality indian ones?

fk_add_id is not reflecting in employee table. and no data in adreess table. pls help me

Awesome explanation. I hope you can make more videos.

Nice Explanation !! You Got 1 Subscriber!!

Hello bro please reply I have to separate entities flight and airport and I don't want to save the data for airport while saving flight,since airport table is already populated Hope it make sense

How does it make sense to make a @onetoone relationship? Why not just embed the class?

Thank you so much. Now I understand how to handle relations :)

How about One to Many & Many to One Mapping and also many to many mapping? Can you make a video for that

You didn't even show how to right at the get mapping, so you just showed how to do the annotations, how is someone meant to known how to make the get request!!!

Much appreciated dude🙂🙏

Just to the point.. Thank you.

bro dhanyawad

So good explained! Just one question, first OneToOne Example, in Entity Employee_Detail you add Address address, which created automatically a FK fk_add_id, should a index be created to that fk_add_id, if data volumn is very big? Thank you!

what will be the difference in table structure b/w uni and bi direction of one to one mapping?

Good explanation.. waiting for next video...
