java - 服务器上存在的交易从不调用

Question

我使用的是 hibernate 4 版本。尝试使用以下代码持久化实体:

    if(surveyUserRequestTO!=null){
        surveyUser = new SurveyUser();

        surveyUser.setAdmin(surveyUserRequestTO.getAdmin());
        surveyOrganization = getEntityManager().find(SurveyOrg.class, surveyUserRequestTO.getOrganizationID());
        if(surveyOrganization !=null){
            surveyUser.setSurveyOrg(surveyOrganization);
        }else{
            return null;
        }
        surveyUser.setUserName(surveyUserRequestTO.getUserName());
        surveyUser.setUserSurveyID(surveyUserRequestTO.getSurveyUserID());

        getEntityManager().persist(surveyUser);

我遇到了以下异常:-

JBAS014134: EJB Invocation failed on component NewUserDataProvider for
 method public
 com.alt.survey.user.transport.output.SurveyUserResponseTO
 com.alt.survey.user.dataprovider.NewUserDataProvider.createNewUser(com.alt.survey.user.transport.input.SurveyUserRequestTO)
 throws java.lang.Exception: javax.ejb.EJBException: Transaction
 present on server in Never call (EJB3 13.6.2.6)

我认为它与 TransactionAttribute 属性有关。我们将不胜感激任何可能的帮助。

您的代码中某处从来没有事务属性(请参阅您的堆栈跟踪)。您不能在具有 NEVER 事务属性的 EJB 方法中启动事务
