我正在使用 Hibernate 和 Spring Data 来建模一个非常简单的域：

@Entity
public class User implements Serializable {

    private static final long serialVersionUID = -5501812656863255674L;

    @Id
    private String emailAddress;

    @Column
    private String forename;

    @Column
    private String surname;

    @Column
    @Enumerated(EnumType.STRING)
    private UserRole role;

    @OneToMany(cascade = { CascadeType.ALL })
    private List<Team> teams;
}

和

@Entity
public class Team implements Serializable {

    private static final long serialVersionUID = -3734641391628154428L;

    private static final BigDecimal STARTING_BUDGET = new BigDecimal(100);

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private int id;

    @Column(unique = true)
    private String name;
}

然后，我在数据服务中有一个“updateUser”方法，该方法按其命名。这个想法是将团队添加到用户，将使用此方法并且级联将导致团队被持久化在数据库中。

@Override
    public void updateUser(final User user) throws IntegrationException {

        if (userRepository.exists(user.getEmailAddress())) {
            userRepository.save(user);
        } else {
            throw new IntegrationException(IntegrationExceptionCode.USER_NOT_FOUND);
        }
    }

然后，我使用 HSQLDB 数据库和 Spring DBUnit 对该方法进行单元测试，以设置初始数据库内容和预期的数据库内容：

初始数据库内容配置

<?xml version="1.0" encoding="UTF-8"?>
<dataset>
    <User emailAddress="user1@test.com" forename="User" surname="One" role="MANAGER" />
    <Player />
    <User_Team />
    <Team />
</dataset>

预期的数据库内容配置

<?xml version="1.0" encoding="UTF-8"?>
<dataset>
    <User emailAddress="user1@test.com" forename="User" surname="One" role="MANAGER" />
    <Player />
    <Team id="1" name="Test Team" totalScore="0" status="INCOMPLETE" remainingBudget="100" />
    <User_Team User_emailAddress="user1@test.com" Teams_id="1" />
</dataset>

然后我有两个测试：一个测试更新成功；一种测试尚未在系统中的用户无法更新的方法。

成功测试

@Test
@ExpectedDatabase("UserData-WithTeam.xml")
public void testUpdateUser_AddedTeam_Success() throws Exception {
    // arrange
    final User user = UserTestDataBuilder.aManager(VALID_EMAIL_ADDRESS, "User", "One").withTeam().build();

    // act
    userDataService.updateUser(user);

    // assert - done by @ExpectedDatabase annotation
}

“用户不存在”测试

@Test
    public void testUpdateUser_AddedTeam_UserDoesNotExist() throws Exception {
        // arrange
        thrownException.expect(IntegrationException.class);
        thrownException.expect(CustomIntegrationExceptionMatcher.hasCode(IntegrationExceptionCode.USER_NOT_FOUND));

        final User user = UserTestDataBuilder.aManagerWithEmailAddress(INVALID_EMAIL_ADDRESS).withTeam().build();

        // act
        userDataService.updateUser(user);

        // assert
        Assert.fail("Exception expected");
    }

“成功”测试工作正常。但是，“失败案例”测试错误并出现以下错误：

似乎暗示它不能拆除在“成功”测试中添加的测试数据（我已经在成功测试中添加了@Ignore 注释并且失败测试通过）。我的问题是为什么？我在 @OneToMany 关系上的级联设置为 ALL，因此应删除作为用户-团队关系的一部分保存的所有实体。

有没有人有任何想法？

我认为你在USER_TEAM表中有一个完整性约束：UPDATE NO ACTION 这就是为什么给出java.sql.SQLIntegrityConstraintViolationException: integrity constraint violation: foreign key no action;
