我继承了使用jBPM 和 Spring的一台器具,如果它能够配置它应该采用的方法,则试图加以说明。

First question: Does jBPM span a single JTA (JDBC and/or Hibernate) transaction across multiple actions in the same transition by default? If not, can it be configured to? So in the example below is there a way to span a transaction across Action1 and Action2.

jBPM actions in this project retrieve services or DAOs (JDBC) from Spring context. For the configuration described below, are jBPM actions and the service / DAO methods they invoke encapsulated in one transaction? DAO and service methods are annotated with @Transactional themselves.

国家定义:

<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>

My jBPM config:
