线程“Thread-10”中的异常java.lang.IllegalStateException

时间：2017-06-15 11:32:00

标签： java multithreading hibernate javafx h2

我不太确定如何解决这个问题，除了我试图填充数据的四个表中的每个表，有时其中一些只是空的。我无法预测哪些是空的。它可以是1和2，或者只是3，或者只是一个表。当其中一个表未填充时，我最终会进入rollback（）catch块。有时它们都有效。这与某种线程中断有关。鉴于以下代码和例外，会出现什么问题？

用于创建和存储对象的线程： 

    new Thread(() -> {
        /* Loop through the "primary key" incidentNumber to create list of objects in memory */
        for (int i = 0; i < incidentNumberList.size(); i++) {
                Incident incident = new Incident();

                /* Save Incidents to Local H2 Database */
                if (!(targetDateList.get(i).isEmpty())) {
                    try {
                        String targetDate = DateUtil.formatTargetDate(targetDateList.get(i));
                        String timeRemaining = DateUtil.getTimeRemaining(targetDateList.get(i));

                        try {
                            // Make sure no transactions are currently running to avoid JPA Error
                            if (!entityManager.getTransaction().isActive()) {
                                // Begin saving Incident objects to H2
                                entityManager.getTransaction().begin();
                                incident.setIncidentNumber(incidentNumberList.get(i));
                                incident.setSummary(summaryList.get(i));
                                incident.setRequestId(requestIdList.get(i));
                                incident.setPriority(priorityList.get(i));
                                incident.setLastModifiedDate((lastModifiedDateList.get(i)));
                                incident.setStatus(statusList.get(i));
                                incident.setTargetDate(targetDate);
                                incident.setTimeRemaining(timeRemaining);
                                incident = entityManager.merge(incident);
                                entityManager.getTransaction().commit();
                            }

                        } catch (Exception e) {
                            entityManager.getTransaction().rollback();
                        }

                    } catch (ParseException e) {
                        e.printStackTrace();
                    }
                }

                /* Create 4 separate lists for each priority level, i.e. Low --> Critical, to populate each of the 4 TableViews */
                if (priorityList.get(i).equals(priorityType)) {
                    switch (priorityType) {
                        case "Low":
                            incidentObjectListGreen.add(incident);
                            break;

                            incidentObjectListYellow.add(incident);
                            break;

1 个答案:

答案 0 :(得分：3)

我认为你的问题在这里：

    } catch (Exception e) {
        entityManager.getTransaction().rollback();
    }

问题＃1 - 你正在挤压异常。您不打印信息，也不记录堆栈跟踪。没有。您只需丢弃可用于诊断问题的所有信息。

问题＃2 - 你正在追赶Exception。这太宽泛了。

问题＃3 - 当你到达调用rollback时，似乎没有要回滚的事务。

如果您解决问题＃1和＃2，我希望问题＃3的原因会被揭示。
