Nice. It will be helpful if you create another video which explains Composite key with one to many relationship between parent and child tables.

[vaishnavinaik]

Very explained !! But what I have observed is even though I have updated primary key from one column to composite key with 2 columns in DB it is working fine in spring boot application without changing entity class. Entity class is still using old PK as @Id.

[luckytheracer]

sir i actually do not understand the need of composite key. Cant it get solved with table normalization. Where is the real usecase still confuse

[prajyotlawande]

You gotta be really careful with Lombok there. @Data already includes @EqualsAndHashCode. Hence using @Data on Employee entity will lead to inclusion of all the Employee fields in its equals and hashcode methods, which I don't quite think will be correct.🙄

[subhashreesahoo]

is it possible to get findby one pair, nd delete and update operation possible?

[varshapardeshi]

Thank You.. Do you have any video on shared primary key for springboot jpa?

[shaileshsingh]

Much needed tutorial since old hibernate wasn't able to support composite key
Now it supports.
Hi sir need to store spatial and JSON data from hibernate.
Can you please make a tutorial.
And cucumber tutorial with spring Boot.

[srikanthchowdary]

Hai bro great explanation can you also explain why we need to override the equals nd hashcode method of compositeId class ?

[akshaydubey..a]

[vrijilk]

Is it possible for auto entity generation based on sql schema instead of manual creation?? Like Asp.net Entity Framework?

[bollywoodssongs]

can you please make video on how to use Employee and Department as @OnetoMany relationship with composite key that will help us more.
