Activiti调用式子流程

本文主要是介绍Activiti调用式子流程，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

1.事物子流程

2.调用式子流程

需要写两个流程定义文件：

其中一个的调用事件和边界事件：

<callActivity id="callActivity" calledElement="my-process-check-order"><extensionElements><activiti:in  source="errorflag" target="errorflag" /><activiti:out source="key1" target="key1" /></extensionElements>
</callActivity><boundaryEvent id="boundary" attachedToRef="callActivity"><errorEventDefinition errorRef="bpmnError"></errorEventDefinition>
</boundaryEvent>

第二个流程定义文件：

<process id="my-process-check-order"><startEvent id="start"/><endEvent id="end"/><parallelGateway id="parallelGateway1" name="并行网关1"/><serviceTask id="pay" name="确认支付" activiti:class="com.syc.activiti.example.MyPayJavaDelegate"/><serviceTask id="take" name="确认收货" activiti:class="com.syc.activiti.example.MyTakeJavaDelegate"/><parallelGateway id="parallelGateway2" name="并行网关2"/><...>
</process>

MyPayJavaDelegate类：

@Override
public void execute(DelegateExecution execution) {LOGGER.info("variables = {}", execution.getVariables());LOGGER.info("run my pay java delegate {}", this);execution.getParent().setVariableLocal("key2", "value2");execution.setVariable("key1", "value1");execution.setVariable("key3", "value3");Object errorflag = execution.getVariable("errorflag");if(Objects.equals(errorflag, true)){throw new BpmnError("bpmnError");}LOGGER.info("pay error");
}

测试：

@Test
@Deployment(resources = {"my-process-subprocess3.bpmn20.xml","my-process-subprocess4.bpmn20.xml"})
public void testSubProcess4(){Map<String, Object> variables = new HashMap<>();variables.put("errorflag", false);variables.put("key0", "value0");ProcessInstance processInstance = activitiRule.getRuntimeService().startProcessInstanceByKey("my-process", variables);Task task = activitiRule.getTaskService().createTaskQuery().singleResult();LOGGER.info("task.name = {}",task.getName());Map<String, Object> variables1 = activitiRule.getRuntimeService().getVariables(processInstance.getId());LOGGER.info("variables1 = {}", variables1);
}

errorflag为false，正常执行：
