mysql - hibernate commit：在日志中显示已提交，但实际上并没有

Question

请看一下这段代码。Persist 适用于名为 Candidate 的表，但不适用于另一个名为 VerifyLink 的表，而 hibernate 显示它正在持久化在日志文件中。请查看下面的日志，在第一种情况下它显示查询“插入候选”，但在第二种情况下，它不显示查询。怎么了？

protected final void doInTransaction(PersistenceActionWithoutResult action) throws EntityAccessorException {
    EntityManager em = emf.createEntityManager();
    try {
        int status = 0;
        status = userTransaction.getStatus();
        if (Status.STATUS_ACTIVE != status){
            count.incrementAndGet();
            userTransaction.begin();
        }
        action.execute(em);
        System.out.println(em);
        status = userTransaction.getStatus();
        System.out.println("status : " + status);
        if (Status.STATUS_ACTIVE == status) {
            if (0 == count.decrementAndGet()) {
                userTransaction.commit();
                System.out.println("committed : ");
            }
        }
    } catch (Exception e) {
        try {
            userTransaction.rollback();
            System.out.println("rolled back :");
            e.printStackTrace();
        } catch (Exception ex) {
            Logger.getLogger(AbstractEntityAccessor.class.getName()).log(Level.SEVERE, null, ex);
        }
        throw new EntityAccessorException(e);
    } finally {
        System.out.println("transaction close :");
        em.close();
    }
}

当我第一次提交某事时

我在 userTransaction.begin() 之后添加了 em.joinTransaction() ，如下所示，这似乎解决了问题。现在可以了。我得到了提示

if (Status.STATUS_ACTIVE != status){
                count.incrementAndGet();
                userTransaction.begin();
                em.joinTransaction();
            }
