Spring Data JPA查询

Question

I have 3 entities in my Database. Entity A has primary key PK-A, Entity B has primary key PK-B, Entity C has primary key PK-C.

Entity A has 1 to many relation with Entity B and Entity B has one to many relation with Entity C

I want to query Entity C based on PK-A (which is actually the Foreign Key in Entity B) in Spring Data JPA. Is it possible?

I tried using the following:

findByTableB_FK-A

But this does not work. Any other suggestion that I can try?

Answer 1

The correct method signature is

TableC findByFK-BFK-A(TableA tableA);

but notice, the - is not allowed in method-names.
