JPA / Hibernate One to One Mapping Example with Spring Boot

In this video tutorial, You’ll learn how to define a one-to-one relationship between two entities using JPA and Hibernate.
Source code on my GitHub repository at github.com/RameshMF/spring-bo....
Hibernate maps the tables in your database to the Entity classes in your application.
You can define relationships among these entities in the same way you define relationships among the tables in your database.
Let’s consider an application that stores a lot of information about its users so that it can provide a personalized experience to them.
In such cases, it makes sense to store users primary details like name, email, password in a USERS table and store all the other secondary details in a separate table called USER_PROFILES, and have a one-to-one relationship between USERS and USER_PROFILES table.

[@sonaligayake9240]

Such nice explanation,l really like it.your speaking like to the point and no other extra stuff like other youtubers, really explained very well👍

[@LibbyAudrey]

This is great! If I want to pull a column different from the first column/ip_id from the UserProfiles table, how would I do that?

[@anitathimothy]

Can you please demonstrate crud operation if there are two tables with referential integrity constraints

[@ashishraroliya9932]

bahut mast tuts h bhai aapke.... bahut help milti h apke codes se

[@mdtanweeralam6871]

Both the table that is user and user profile has same column name "id" as primary key, is there any relationship between these two same column name "id".

[@prajwaldhanke6087]

hi ramesh.... your videos are very usefull for me.

[@Pain-qu5nr]

Can I get all the details from both tables? Using the findByID method in UserRepository???

[@harikrishna3538]

HI Ramesh your explanation is so nice.

[@JavaGuides]

Thank you.

[@yogeshchoudhar5469]

Sir, ekdam Bhari 🔥🔥

[@suvammohanty7105]

No words for u just love it ❣❣❣

[@b1onic98]

Good job, keep it up and thank you

[@javatechnology4481]

Very useful. We want video tutorials on many to many and one to many mappings. 👍

[@trademoneynothealth]

I have a doubt its working for me this way but if i try to have userid as foreign key in userprofile table its getting inserted as null i have changed all the annotations as well

[@sarthakthakur87]

Sir make a video on Spring REST with hibernate mappings.
That will be great

[@untipejoahi]

No words, man. I really like your videos: Explicit, simple and clean-codding. Keep it up!

[@gyanasahu1006]

Please stick to table structure shown @1:30. According to that in Users class it should be @JoinColumn(name = "user_profile_up_id", referencedColumnName = "up_id"). It looked confusing while explaining.

[@hanumanhiwarkar3350]

Very nice and simple explanation love your teaching. BTW the keyboard sounds amazing

[@abdelhamidtahiri9462]

you can do un video about how using inhereated class with JPA ..

[@sreenivasulu47]

Good Explanation...

[@nicolasleger7134]

Wonderful. Good Job

Great Teaching ... :)

[@nis02002]

[@freeplay18]

how to add data dynamically and access them through postman in one to one mapping ,pls make a video on this, btw nice tutorial

[@manojarya7676]

Awesome....😍👌👍🔥.

[@umaparvathi606]

This also nice sir

[@kotinkarwak]

Anyone please explain to me the need for the statement run in setting up the user.
He created the instances for use and then for profile. Set the user.setprofile... and profile.setuser. why is the profile.setuser part needed in cascade is set to all and we only calling .save on the user repository? Am confusing my little brains here so would appreciate any explainers. Thanks for the vids

[@Vaishu219]

First you check the table relationship on er model it has bidirectional

[@smileyakhi165]

Sir please provide the source code link. Am almost done but there is small mistake for me. Link plz sir

[@subramanianchenniappan4059]

thanks bro

[@kvnagendra5354]

19:58 sir sir u saved user only with userRepository but what about userprofile obj how does it saved

[@eliasnicolas6443]

hibernate does it for you

[@jingli2168]

why u need to add userProfileRepository injected in main???

[@JavaGuides]

That is not required. If you want check bidirectional one to one mapping then you can use it

[@sarthakthakur87]

NICEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE

[@seemaprajapati964]

Ramesh pls put some energy in yourself while teaching otherwise u r awesome man

[@radhapandikunta3819]

Child table forgein key inserting as null

[@paulmimicry9147]

How to fetch?? Inserting is easy but how about fetch?

[@JavaGuides]

Use findById(), findAll() methods to fetch the data. Inserting is quite tricky in association but fetching is very easy.
