Question

我正在尝试为添加到CrudRepository接口的自定义方法编写单元测试。面临的问题是所有Crud defualt方法都在执行，而我的自定义方法始终返回空数据集。例如findOne（id），findAll可以正常工作，没有任何问题。目前正在努力寻找答案。

数据库表帐户的实体类

@Entity(name = "account")
public class Account implements Serializable {

    /**
    * UUID
    */
    private static final long serialVersionUID = 3918263534182744304L;
    /**
    * Primary Key account Id {@link Long}
    */
    @Id
    @Column(name = "accountId")
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long accountId;
    /**
    * Actual accountID received from Sales-force
    */
    @Size(max = 18)
    @Column(name = "id")
    private String id;
    /**
    * Name of the account
    */
    @Size(max = 255)
    @Column(name = "Name")
    private String name;

    /**
    * Type of the account
    */
    @Size(max = 255)
    @Column(name = "type")
    private String type;

    //other fields and getter and setters
}

存储库界面

@Repository
@Transactional(propagation=Propagation.REQUIRES_NEW)
public interface AccountRepository extends CrudRepository<Account, Long>{
    Collection<Account> findByType(final String type);
}

春季单元测试课

@RunWith(SpringRunner.class)
@DataJpaTest
@ActiveProfiles("test")
@Transactional
public class AccountRepositoryTest {

    @Autowired
    private TestEntityManager entityManager;

    @Autowired
    private AccountRepository accountRepository;

    private Long accountId_1 = 1L;
    private Long accountId_2 = 2L;

    @Before
    public  void init() {

         //account 1
         Account account = setAccount("Credit");
         entityManager.persist(account);
         entityManager.flush();
         logger.info("Account Id Inserted: " + account.getAccountId() + " | " + account.toString());
         accountId_1 = account.getAccountId();

         //account 2
         account = setAccount("Debit");
         entityManager.persist(account);
         entityManager.flush();
         logger.info("Account Id Inserted: " + account.getAccountId() + " | " + account.toString());
         accountId_2 = account.getAccountId();
    }

    @Test
    public void accountTypeTest() {
        Account retrieved = accountRepository.findOne(accountId_2);
        //correctly returning the object with accountId == accountId_2

        Collection<Account> accountRetrived = accountRepository.findByType(retrieved.getType());
        // Always returning empty result set
        assertTrue(accountRetrieved.size() > 0); 
    }

    /*
    * Method will create the Account dummy object.
    */
    private Account setAccount(final String type) {
        final Account account = new Account();
        account.setiD("ID");
        account.setName("AccountName");
        account.setType(type);
        return account;
    }

}

问题是当使用Crud的默认方法时，它可以正常工作，正确重现对象。例如，如果使用的是findOne（id）或findAll（）。
当我尝试从日志中的存储库中调用findByType（String type）方法时，我可以看到查询正确打印（在跟踪模式下启用了日志，并且还看到了正确传递的值）
为什么无法接收数据？
