Activiti + Hibernate：常見事務管理器

Question

我嘗試使用Activiti公用事務管理器& Hibernate。他們有共同的數據庫。我試着先與Hibernate的幫助，然後保存在同一實體的Activiti的幫助：

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

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

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

問題：

我沒有看到客戶實體的任何記錄Activiti中的ACT_RU_VARIABLE表。

問：

如何確保Activiti的使用相同的事務中休眠？

此外：

的applicationContext.xml

Answer 1

答案很簡單：過程變量被刷新到DB只有當流程到達等待stait，成品或勞克異步任務。處理完成後清理ACT_RU_VARIABLE表。因此，要查看ACT_RU_VARIABLE表中的任何記錄，您需要在UserTask期間檢查它。
