Spring Framework和Jpa Repository返回无效的数据库数据

Question

I'm testing a service that returns some information from the DB.

I'm using Spring framework and JPA Repository to obtain the data from the DB in order to compare it with the service output.

public interface UsersAccountsRepo extends JpaRepository<UsersAccounts, Long> {

    List<UsersAccounts> findAllByUserId(String userId);

}

Calling the method:

List<UsersAccounts> usersAccounts = UsersAccountsRepo.findAllByUserId(userId);

The db has 3 entries for this userId = 123, with the following format:

• 123 / 30001
• 123 / 30002
• 123 / 30003

But the method returns a list of three identical entries:

• 123 / 30001
• 123 / 30001
• 123 / 30001

I have tried using findByUserId(String userId), but it has the same result.

Thank you.

Answer 1

Sorry for not giving out all the relevant information, I didn't think it had an impact.

As it turns out, the table mapping had the @Id annotation set on the wrong column. The column that had the @Id didn't have unique data as opposed to the other column.

Changing the annotation's place solved the issue.

Thank you.
