Spring boot JpaObjectRetrievalFailureException:找不到id为xxx的myapp.server.layer3persistence.UserData

我需要你的帮助，因为我不明白发生了什么：我有一个异常是由一个永远不会生成这个特定异常的代码引发的。我使用的是SpringBootV2.2.7.0版本

例外情况是：

SERVER ERROR: Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.orm.jpa.JpaObjectRetrievalFailureException: Unable to find myapp.server.layer3persistence.UserData with id 4673fa77-c8f2-45ac-886d-b5a8433044d6; nested exception is javax.persistence.EntityNotFoundException: Unable to find myapp.server.layer3persistence.UserData with id 4673fa77-c8f2-45ac-886d-b5a8433044d6] with root cause

堆栈跟踪是：

UserProfile existingProfile = userProfileRepository.findByProfileId(userProfile.getProfileId()).get();

有趣的是：

    at myapp.server.layer2services.UserServices.addProfile(UserServices.java:332)
    at myapp.server.layer1controllers.UserController.addSingleProfile(UserController.java:68)

让我们试着看一下有问题的台词：

用户控制器：66-69

    @PostMapping("/addSingleProfile")
    public void addSingleProfile(@RequestHeader String authToken, @RequestHeader String deviceId, @RequestBody String json) throws IOException {
        userServices.addProfile(authToken, deviceId, json, true);
    }

java:326-346

public void addProfile(String authToken, String deviceId, String json, boolean isSingleProfile) throws IOException {
        UserData userData = findUserByAuthTokenOrRequestLogout(authToken, deviceId);
        UserProfile userProfile = new UserProfile(userData, new Gson().fromJson(json, UserProfileDAO.class));

        // is it a new userProfile or an existing one to be updated?
        if (userProfileRepository.existsByProfileId(userProfile.getProfileId())) {
            UserProfile existingProfile = userProfileRepository.findByProfileId(userProfile.getProfileId()).get();
            // the profile exists, so we update it
            userProfile.setId(existingProfile.getId());
        };

        if (isSingleProfile) {
            userData.getSingleProfiles().add(userProfile);
        } else {
            userData.getOrganizationProfiles().add(userProfile);
        }

        userProfileRepository.save(userProfile);

        userDataRepository.save(userData);
    }

行UserServices.java:332（在堆栈跟踪中指示）是：

但是此行不能抛出给定的异常，因为它在if子句中：

        if (userProfileRepository.existsByProfileId(userProfile.getProfileId())) {
            UserProfile existingProfile = userProfileRepository.findByProfileId(userProfile.getProfileId()).get();
            // the profile exists, so we update it
            userProfile.setId(existingProfile.getId());
        };

UserProfileRepository的实现如下：

@Repository
@Transactional
public interface UserProfileRepository extends CrudRepository<UserProfile, String> {

    public Optional<UserProfile> findByProfileId(String profileId);
    public Optional<UserProfile> findByName(String name);
    public Optional<UserProfile> findByNameIgnoreCase(String name);
    public Optional<UserProfile> findByNameAndGroupKey(String name, String groupKey);

    public boolean existsByProfileId(String profileId);
}

---

通过更新

@ManyToOne

注释，解决了我案例中的类似问题：

@NotNull
@JoinColumn(nullable = false)
@ManyToOne(optional = false, fetch = FetchType.LAZY)

---

添加：

nullable=false

，

optional=false，fetch=FetchType.LAZY

plus-

@NotNull

（javax.validation.constraints.NotNull）

Hi@Francesco Galgani我认为数据库表用户与4673fa77-c8f2-45ac-886d-b5a8433044d6]连接或数据库中的某些不好的东西有类似的问题，非常感谢您的回复。事实上已经好几个月了，我不记得我是如何解决这个问题的（如果我解决了的话）。我接受你的回答，但因为已经很久了，我没有可能去证实。我只记得我通过在application.properties中添加以下行解决了各种奇怪的问题：

spring.jpa.properties.hibernate.enable\u lazy\u load\u no\u trans=true

@NotNull
@JoinColumn(nullable = false)
@ManyToOne(optional = false, fetch = FetchType.LAZY)
