Question

我尝试使用Activiti＆amp; amp;休眠。他们有共同的DB。我首先在Hibernate的帮助下尝试保存同一个实体，然后在Activiti的帮助下保存：

Session session = ((SessionFactory) applicationContext.getBean("sessionFactory")).openSession();
session.beginTransaction();

session.save(client);
execution.setVariable("client", client);

session.getTransaction().commit();
session.close();

问题：

我没有在activiti的ACT_RU_VARIABLE表中看到客户端实体的任何记录。

问题：

如何确保Activiti使用与Hibernate相同的事务？

此外：

Answer 1

答案很简单：只有当进程到达等待，完成或非常异步的任务时，才会将进程变量刷新到DB。并且在处理完成后清理ACT_RU_VARIABLE表。因此，要查看ACT_RU_VARIABLE表中的任何记录，您需要在UserTask期间检查它。
