Spring Boot 如何在仓库类的单元测试中模拟lombok @data stackoverflow错误?

如果使用Lombok的@Data注解而不是单独的@Getter和@Setter注解,我的实体之间会有一个关系抛出一个堆栈溢出错误。现在这个问题已经解决了,但是我想在我的存储库测试中为它编写一个单元测试。但是,我不确定如何实现它,也没有找到它的示例。
下面是我的实体类:

@Entity
@Table(name = "users")
@Builder
//@Getter
//@Setter
@Data
@AllArgsConstructor
@NoArgsConstructor
public class UserEntity {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(name = "id")
    private UUID id;

    @Column(name = "name")
    private String name;

    @ManyToMany
    @JoinTable(
            name = "users_hobbies",
            joinColumns = @JoinColumn(name = "user_id", referencedColumnName = "id"),
            inverseJoinColumns = @JoinColumn(name = "hobby_and_interest_id", referencedColumnName = "id"))
    private Set<HobbyAndInterestEntity> hobbyAndInterestEntities;

    @ManyToOne(fetch = FetchType.LAZY, cascade = CascadeType.MERGE)
    @JoinColumn(name = "hometown_id", referencedColumnName = "id")
    private HometownEntity hometownEntity;
@Entity
@Table(name = "hometown")
@Builder
@Data
@AllArgsConstructor
@NoArgsConstructor
public class HometownEntity {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(name = "id")
    private UUID id;

    @Column(name = "city")
    private String city;

    @Column(name = "country")
    private String country;

    @OneToMany(mappedBy = "hometownEntity", fetch = FetchType.LAZY, cascade = CascadeType.ALL, orphanRemoval = false)
    private Set<UserEntity> userEntitySet;
@Data
@AllArgsConstructor
@NoArgsConstructor
public class HobbyAndInterestEntity {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(name = "id")
    private UUID id;

    @Column(name = "title")
    private String title;

    @ManyToMany(fetch = FetchType.LAZY, mappedBy = "hobbyAndInterestEntities")
    private Set<UserEntity> userEntities;

下面是我对一个没有异常的用例的测试,我打算修改它来测试异常场景:

@Test
    void testGetUser() {

        UserEntity userEntity = saveUserEntity();

        assertTrue(userRepository.findAll().size() > 0);
        userEntity = userRepository.findById(userEntity.getId()).orElse(null);
        assertNotNull(userEntity);

        UserEntity finalUserEntity = userEntity;
        assertAll(
                () -> assertEquals("anyName", finalUserEntity.getName()),
                () -> assertEquals("anyCountry", finalUserEntity.getHometownEntity().getCountry()),
                () -> assertTrue(finalUserEntity.getHobbyAndInterestEntities().size() > 0));

        finalUserEntity.getHobbyAndInterestEntities().forEach(h -> assertEquals("anyInterest", h.getTitle()));
    }

    @NotNull
    private UserEntity saveUserEntity() {

        HometownEntity hometownEntity = HometownEntity.builder().city("anyCity").country("anyCountry").build();
        hometownEntity = hometownRepository.save(hometownEntity);

        HobbyAndInterestEntity hobbyAndInterestEntity = HobbyAndInterestEntity.builder()
                .title("anyInterest")
                .build();
        hobbyAndInterestEntity = hobbyAndInterestRepository.save(hobbyAndInterestEntity);
        Set<HobbyAndInterestEntity> hobbyAndInterestEntities = new HashSet<>();
        hobbyAndInterestEntities.add(hobbyAndInterestEntity);

        UserEntity userEntity = UserEntity.builder()
                .name("anyName")
                .hometownEntity(hometownEntity)
                .hobbyAndInterestEntities(hobbyAndInterestEntities)
                .build();

        return userRepository.save(userEntity);
    }

总之,我知道当我有@Data注解时,应用程序会抛出堆栈溢出,所以我想编写一个测试,当我修改实体类以使用@Getter和@Setter时,该测试会失败并再次通过,但不确定这里需要什么,希望能得到一些指导。
非常感谢。

请检查@Data注解here@Data是所有字段上@ToString@EqualsAndHashCode@Getter、所有非最终字段上@Setter和@RequiredArgsConstructor的快捷方式!当您调用toStringequalshashCode方法时,关系实体将在数据库中查询。您可以尝试查看生成的源代码,在那些方法中使用了关系实体。我认为它可能会抛出堆栈溢出错误。
