我们有一个Spring应用程序版本4.3.3.RELEASE使用Hibernate 5.1.0.Final和Java 8 该应用程序有一个rmi接口，它向Java胖客户端应用程序公开服务。该应用程序还公开了Spring Restful Webservices。 导致我们遇到问题的服务作为rmi服务和暴露在外。以RMI方式调用服务工作得很好，但调用restful ws会产生javax.persistence.TransactionRequiredException，如下所示。Spring rmi服务的工作原理并不像平静ws
我以为我找到了答案，这件事情在这里，但我似乎无法得到正确的事情： Spring @Transactional not working
We'we尝试过许多不同的东西，比如：
@Transactional(propagation = Propagation.REQUIRES_NEW)
但我猜测这里的问题是我有两个spring-config文件，但没有在我的springrest-config.xml中定义正确的东西。
有谁知道如何解决这个问题？
这里是DAO方法：
@Override
public void deleteFormReplyForInvitation(Long id) {
try {
entityManager.createQuery("DELETE FROM FormReply where id = " + id).executeUpdate();
} catch (Exception e) {
throw new RuntimeException(e);
}
}
这里是服务代码：
@Override
@Transactional
public String withdrawConsent(final String username, final Patient patient, final String method) {
try {
List<Invitation> invitations = invitationService.getInvitationsForPatient(patient);
for (Invitation invitation : invitations) {
if (invitation.getFormReply() != null) {
formReplyService.deleteFormReply(invitation.getFormReply().getId());
}
if (!invitation.getReminders().isEmpty()) {
reminderService.deleteReminders(invitation);
}
invitationService.deleteInvitation(invitation.getId());
}
eventlogService.deleteEventlog(patient);
EntryKind entryKind = entryKindService.getEntryKind(1);
eventlogService.addEventlog(patient, eventlogDataDeleted, entryKind, true, username);
addConsent(patient, method, username);
patient.setActive(false);
patientService.saveOrUpdatePatient(patient);
return "OK";
} catch (Exception e) {
logger.error("Feil oppstått i withdrawConsent.", e);
return "ERROR";
}
}
@Override
@Transactional
public String withdrawConsent(final String birthNumber, final String programCode) {
String encryptedPNR = encryptionService.encryptDBQ(birthNumber);
Cancertype cancertype = cancertypeService.getCancertypeByCode(programCode);
Patient aPatient = patientService.getPatient(encryptedPNR, cancertype);
return withdrawConsent("WebService", aPatient, "Webservice");
}
这里是其余控制器：
@RequestMapping(value = "/withdrawconsent", method = RequestMethod.GET)
@Transactional
String withdrawConsent(@RequestParam("programcode") final String programcode, @RequestParam("birthnumber") final String birthnumber) throws CancertypeException {
return consentService.withdrawConsent(birthnumber, programcode);
}

我们用来调用WebService的我的URL：■ http://xxx-xxx-xxx:8080/proms-services-1.0-SNAPSHOT/withdrawconsent?birthnumber=01016512345&programcode=PR

由于组件扫描，您正在创建2个服务实例。您的servlet应该只扫描与Web相关的bean（'@ Controller'）并忽略其余部分，因为它将由'ContextLoaderListener'加载。您现在有两个服务实例，正确的是来自父上下文（“ContextLoaderListener”）的实例，错误的是“DispatcherServlet”中的on。 –
谢谢@M-Denium，解决了这个问题。它导致我们遇到了一个新问题（将一个集合与两个开放会话相关联的非法尝试）我们通过使用合并而不是更新实体来解决这个问题。 –
