jBPM 6.1无法恢复过程 | processInstance

本文介绍了jBPM 6.1无法恢复过程的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我们可以暂停这样的流程实例:

We can suspend a process instance like this :

org.jbpm.process.instance.ProcessInstance processInstance = //...;
processInstance.setState(STATE_SUSPENDED);

并恢复它:

kieSession.getWorkItemManager().completeWorkItem(processInstance.getId(), params);

但是它不起作用！ ...是什么问题?

but it doesn't work! ... what is the problem?

谢谢.

推荐答案

要恢复进程，请使用processInstance.setState(ProcessInstance.STATE_ACTIVE). WorkItemManager可以对workItems(Web服务调用，人工任务，客户处理程序等)进行操作，而不是对processInstances进行操作.

To resume a process, use processInstance.setState( ProcessInstance.STATE_ACTIVE ). The WorkItemManager operates on workItems (web service calls, human tasks, customer handlers etc.) rather than processInstances.

尝试以下代码:

    KieSession ksession=......
    ProcessInstance processInstance = ksession.startProcess(......
    //suspend:
    SuspendProcessInstanceCommand susp=new SuspendProcessInstanceCommand();
    susp.setProcessInstanceId(processInstance.getId());
    ksession.execute(susp);
    //confirm suspended:
    assertEquals(ProcessInstance.STATE_SUSPENDED, ksession.getProcessInstance(processInstance.getId()).getState());

    //resume:
    ResumeProcessInstanceCommand res=new ResumeProcessInstanceCommand();
    res.setProcessInstanceId(processInstance.getId());
    ksession.execute(res);
    //confirm active:
    assertEquals(ProcessInstance.STATE_ACTIVE, ksession.getProcessInstance(processInstance.getId()).getState());
