我已经问过这个问题两次了，但是我是 stackoverflow 的新手，而且我似乎不知道在这里格式化我的示例代码的规则。现在我决定给出完整的电话堆栈，我希望我能解释一下情况，因为一切都太奇怪了，我找不到形容词来形容它。首先，我将为您提供与该问题有关的类的来源。我的实际问题在页面末尾。大段代码是为了以防万一，因为我不知道我的问题可能是什么解释。这是一个从我的 flex 应用程序获取调用的服务外观。
public class ServiceFacade implements IAuthenticationService, IProfileService, ICampaignService {
@Autowired
private IAuthenticationService authenticationService;
@Autowired
private IProfileService profileService;
@Autowired
private ICampaignService campaignService;
public void login(User user) throws AuthenticationException{
authenticationService.login(user);
}
@Override
public void logout() throws AuthenticationException {
authenticationService.logout();
}
@Override
public void sendForgottenPassword(String email) {
authenticationService.sendForgottenPassword(email);
}
@Override
public Profile getProfile(Long userId) {
return profileService.getProfile(userId);
}
@Override
public Profile updateProfile(Profile profile) {
return profileService.updateProfile(profile);
}
@Override
public Collection<String> getSocialConnectionsTypes(Long userId) {
return profileService.getSocialConnectionsTypes(userId);
}
@Override
public List<Email> findDuplicateEmails(Long profileId, List<Email> emails) {
return profileService.findDuplicateEmails(profileId, emails);
}
@Override
public Campaign getCampaign(Long campaignId) {
return campaignService.getCampaign(campaignId);
}
@Override
public Campaign updateCampaign(Campaign campaign) {
return campaignService.updateCampaign(campaign);
}
@Override
public void removeCampaign(Long campaignId) {
campaignService.removeCampaign(campaignId);
}
@Override
public void setPools(Long campaignId, Collection<Pool> pools) {
campaignService.setPools(campaignId, pools);
}
@Override
public void addPool(Long campaignId, Pool pool) {
campaignService.addPool(campaignId, pool);
}
@Override
public void removePool(Long campaignId, Pool pool) {
campaignService.removePool(campaignId, pool);
}
@Override
public List<Campaign> getCampaigns() {
return campaignService.getCampaigns();
}
@Override
public void updatePool(Long campaignId, Pool pool) {
campaignService.updatePool(campaignId, pool);
}
}
对我的问题很重要的方法是findDuplicateEmails方法。
profileService在以下类中实现：
public class ProfileService implements IProfileService {
@Autowired
private IProfileManager profileManager;
@Override
public Profile getProfile(Long userId) {
return profileManager.getProfile(userId);
}
@Override
public Profile updateProfile(Profile profile){
profileManager.updateProfile(profile);
return profile;
}
@Override
public Collection<String> getSocialConnectionsTypes(Long userId) {
return profileManager.getSocialConnectionsTypes(userId);
}
@Override
public List<Email> findDuplicateEmails(Long profileId, List<Email> emails) {
return profileManager.findDuplicateEmails(profileId, emails);
}
}

profileManager的实现是以下类：
public class ProfileManager implements IProfileManager {
@Autowired
private IProfileDao profileDao;
@Autowired
private ISectionManager autoCompleteManager;
@Autowired
private IUserSecurityService userSecurityService;
@Transactional
public Profile getProfile(Long userId) {
return profileDao.getProfileByUser(userId);
}
@Transactional
public void updateProfile(final Profile profile) {
List<Major> notApprovedMajors = extractNotApprovedMajors(profile);
List<Degree> notApprovedDegrees = extractNotApprovedDegrees(profile);
List<School> notApprovedSchools = extractNotApprovedSchools(profile);
List<Language> notApprovedLanguages = extractNotApprovedLanguages(profile);
List<Position> notApprovedPositions = extractNotApprovedPositions(profile);
List<Company> notApprovedCompanies = extractNotApprovedCompanies(profile);
List<Country> notApprovedCountries = extractNotApprovedCountries(profile);
List<City> notApprovedCities = extractNotApprovedCities(profile);
List<Certificate> notApprovedCertificates = extractNotApprovedCertificates(profile);
autoCompleteManager.updateAll(notApprovedMajors);
autoCompleteManager.updateAll(notApprovedDegrees);
autoCompleteManager.updateAll(notApprovedSchools);
autoCompleteManager.updateAll(notApprovedLanguages);
autoCompleteManager.updateAll(notApprovedPositions);
autoCompleteManager.updateAll(notApprovedCompanies);
autoCompleteManager.updateAll(notApprovedCountries);
autoCompleteManager.updateAll(notApprovedCities);
autoCompleteManager.updateAll(notApprovedCertificates);
profileDao.updateProfile(profile);
}
@Override
public List<Email> findDuplicateEmails(Long profileId, List<Email> emails) {
Profile persistedProfile = profileDao.findById(profileId);
if (persistedProfile.getContact() == null)
{
persistedProfile.setContact(new Contact());
}
List<Email> resultEmails = new ArrayList<Email>();
for (int i = 0; i < emails.size(); i++) {
if ((!userSecurityService.guaranteeUniquePrincipal(emails.get(i)) &&
!isPersistedInThePersistentCollection(emails.get(i), persistedProfile.getContact().getEmails())) ||
isDuplicateInTheCurrentCollection(emails.get(i), emails, i + 1)) {
resultEmails.add(emails.get(i));
}
}
return resultEmails;
}
private boolean isDuplicateInTheCurrentCollection(Email emailToCheck, List<Email> emails, int index)
{
for (int i = index ; i < emails.size(); i ++) {
if (emails.get(i).getEmailAddress().equals(emailToCheck.getEmailAddress())) {
return true;
}
}
return false;
}
private boolean isPersistedInThePersistentCollection(Email emailToCheck, Collection<Email> emails)
{
if (emails == null) {
return false;
}
for (Email persistedEmail : emails) {
if (persistedEmail.getEmailAddress().equalsIgnoreCase(emailToCheck.getEmailAddress())) {
return true;
}
}
return false;
}
}

现在，在这个简短的背景之后，这是我的问题：
我正在使用带有 Spring 的 HibernateTemplate 的 Hibernate。我发现在findDuplicateEmails方法中，一些来自 flex 应用程序的全新实体会自动保存。这很奇怪，在调试过程中我发现即使我更改了ProfileManager 中的findDuplicateEmails方法，它看起来像：
@Override
public List<Email> findDuplicateEmails(Long profileId, List<Email> emails) {
Email email = new Email();
return null;
}
实体电子邮件会自动保存。我还发现，如果实体的标识符不是“email”，而是其他东西，比如“newEmail”或“email1”，或者其他东西，那么没有问题，当且仅当我成功时，实体才会持久化执着的。这个问题只存在于这个类中，最后，这个问题只出现在电子邮件中。我的意思是，如果我有Phone phone = new Phone();实体电话，则仅在我希望的时候才会保留。
flex 应用程序首先检查用户输入的电子邮件是否唯一，然后在一些用户交互后调用该方法updateProfile()，如果输入的数据有效。
