In normal case we have one to one parent child relationships.
Like one parent class User and it has a child UserType.

@Data public class User { @Id private Long id; private String name; private UserType type; } @Data public class UserType { @Id private Long id; private String type; } 

Having schema as :

Table User:
Column : id (Primary key), name , user_type_id foreign key to UserType.id column

Table UserType
Column : id (Primary key), name

User type is master table, whenever we need to add user, based on type we select and create user.

This should work normally with UserRepository<User, Long>.

But when we use this schema and classes, it generates wrong query as it accepts User.id should be present in UserType table.

Which is wrong as this is master table, I dont want it to grow when new user added.
