我已經繼承了一個使用jBPM和Spring的應用程序,並試圖弄清楚它是否按照應有的方式配置。jBPM + Spring交易共享和範圍
第一個問題:默認情況下,jBPM是否在同一轉換中的多個操作之間跨越單個JTA(JDBC和/或Hibernate)事務? 如果沒有,是否可以配置? 所以在下面的例子中,有一種跨越Action1和Action2跨越事務的方法。
此項目中的jBPM操作從Spring上下文中檢索服務或DAO(JDBC)。 對於下面描述的配置,jBPM操作和它們調用的服務/ DAO方法是封裝在一個事務中的嗎? DAO和服務方法用@Transactional自己註釋。
狀態定義:
<state name="SomeState">
<event type="node-enter">
<action class="SomeAction"/>
</event>
<transition name="transition1" to="finish">
<action class="Action1"/>
<action class="Action2"/>
</transition>
<transition name="transition.stop" to="finish"/>
</state>
