错误事件

好像都是中断的。非中断没测出来！！！

<!-- 定义错误 -->
<error id="error1" name="errorCode1" errorCode="123456"/>
<error id="error2" name="errorCode2" errorCode="123456"/>

开始事件

开始事件只能在事件子流程中被触发，也不能用于启动流程，总是中断的。

可以用于捕获工作流启动时可能出现的各种错误情况，并根据具体的业务需求进行相应的处理。

<!-- 错误开始事件 -->
<startEvent id="sid-9f66c2ee-3281-486e-9aea-e27f29dad682" name="错误开始事件">
  <!-- 引用错误码 -->
  <errorEventDefinition errorRef="error1"/>
</startEvent>

边界事件

总是用于用户任务或子流程上。

当某个任务发生错误时，可以通过错误边界事件来捕获并处理该错误，以保证流程的正常执行。

<!-- 错误边界事件1 非中断 -->
<boundaryEvent id="sid-ef65efec-11aa-4c72-98c5-3cc42a2a8229" attachedToRef="sid-7f48d1e2-a7e5-4717-ad18-cbc5a78b8113" cancelActivity="false" name="错误边界事件1">
  <!-- 引用错误码 -->
  <errorEventDefinition errorRef="error1"/>
</boundaryEvent>

结束事件

错误结束事件就是流程抛出一个bpmn错误。然后被工作流的错误边界事件获取。

错误结束事件会在流程到达错误结束事件的时候抛出错误，并结束当前的流程分支。错误可以使用匹配的错误边界事件捕获。如果找不到匹配的错误边界事件，将会抛出异常。

<!-- 错误结束事件 -->
<endEvent id="sid-1600e3d8-61f9-428f-82c8-c048ef84c774" name="错误结束事件">
  <!-- 引用错误码 -->  
  <errorEventDefinition errorRef="error1"/>
</endEvent>

代码实现

开始事件

错误开始事件针对某个事件子流程触发。（虚线子流程框）

测试流程

java">@Test
public void deployAndStartProcessByErrorStart() {
    // 部署流程
    Deployment deploy = repositoryService.createDeployment()
            .addClasspathResource("processes/error-start.bpmn20.xml")
            .deploy();
    System.out.println("deploy = " + deploy);

    // 启动流程
    String processDefinitionKey = "error-start";
    ProcessInstance processInstance = runtimeService.startProcessInstanceByKey(processDefinitionKey, processDefinitionKey + ":100001");
    System.out.println("processInstance = " + processInstance);
}

流程执行步骤

// 1.部署并启动流程
// 2.触发服务任务，服务任务监听器抛出异常，错误码errorCode
// 3.子流程接收到错误码为errorCode，触发错误开始事件
// 4.触发子流程服务任务
// 5.结束流程

边界与结束事件

流程图设计一个子流程，然后子流程里面有一个错误结束事件。外面的错误捕获边界任务就会捕获异常。捕获了异常后由于是错误边界先去捕获异常，所以捕获错误事件分支会先执行，然后结束。正常结束事件节点所在的分支不会执行。

开始 - 子流程开始 - 排他网关 - 错误结束事件 - 错误边界事件 - 结束流程

自定义错误监听器

java">@Component
public class MyThrowErrorDelegateListener implements JavaDelegate, Serializable {

    private static final long serialVersionUID = 1L;

    @Override
    public void execute(DelegateExecution execution) {
        System.out.println("《================服务任务错误监听器================》");
        System.out.println("当前时间：" + DateUtil.format(new Date(), DatePattern.NORM_DATETIME_PATTERN));
        System.out.println("delegateTask.getProcessInstanceId() = " + execution.getProcessInstanceId());
        System.out.println("delegateTask.getProcessInstanceBusinessKey() = " + execution.getProcessInstanceBusinessKey());
        System.out.println("delegateTask.getEventName() = " + execution.getEventName());
        System.out.println("execution.getCurrentFlowElement().getName() = " + execution.getCurrentFlowElement().getName());
        // 抛出异常
        String errorCode = "123456";

测试流程

java">@Test
public void deployAndStartProcessByErrorBoundaryAndEnd() {
    // 部署流程
    Deployment deploy = repositoryService.createDeployment()
            .addClasspathResource("processes/error-boundary-end.bpmn20.xml")
            .deploy();
    System.out.println("deploy = " + deploy);

    // 启动流程
    Map<String, Object> variables = new HashMap<>();
    variables.put("assignee", "user123456");
    String processDefinitionKey = "error-boundary-end";
    ProcessInstance processInstance = runtimeService.startProcessInstanceByKey(processDefinitionKey, processDefinitionKey + ":1000011", variables);
    System.out.println("processInstance = " + processInstance);
}

@Test
public void completeTaskForErrorBoundaryAndEnd() {
    // 查询任务
    Task task = taskService.createTaskQuery().processInstanceId(PROCESS_INSTANCE_ID).taskAssignee("user123456").singleResult();
    System.out.println("task = " + task);
    // 完成任务
    Map<String, Object> hashMap = new HashMap<>();
    hashMap.put("save", true);
    taskService.complete(task.getId(), hashMap, true);
}

流程执行步骤

// 1.部署并启动流程
// 2.当前任务保存用户任务
// 3.完成用户任务save=false
// 4.触发错误结束事件，边界事件捕获到errorCode=123456，流程循环保存用户任务（如果一直是false）
// 5.当完成用户任务save=true
// 6.子流程结束
// 7.触发服务任务
// 8.结束流程
