Flowable结束事件
结束事件顾名思义就是流程结束的事件，除了前面遇到的空结束事件外，结束事件还包括如下几种：
-
错误结束事件 -
中断结束事件 -
取消结束事件
1.错误结束事件
当流程执行到达错误结束事件（error end event）时，结束执行的当前分支，并抛出错误。这个错误可以由匹配的错误边界中间事件捕获。如果找不到匹配的错误边界事件，将会抛出异常。通过具体案例来详细讲解：

定义的error
<error id="error01" errorCode="error01"></error>
在子流程中，当flag的数据为0的时候，就会触发错误结束事件
<sequenceFlow id="1111" sourceRef="12222" targetRef="xxxxx44">
<conditionExpression xsi:type="tFormalExpression"><![CDATA[${flag==0}]]></conditionExpression>
</sequenceFlow>
然后我们在子流程上绑定了一个错误边界事件，绑定的也是error01,也就是当子流程触发错误结束事件，就会触发这个边界事件，进而完成自动任务三。
流程中关联的三个自动任务都只是输出一个打印语句~
然后我们需要做的操作有，部署，启动流程绑定流程变量flag的值为0，然后就可以看输出结果了
/**
* 部署
*/
@Test
public void test02() throws Exception{
Deployment deployment = processEngine.getRepositoryService().createDeployment()
.addClasspathResource("错误结束事件.bpmn20.xml")
.name("错误结束事件")
.deploy();
System.out.println("-----");
}
然后启动流程
/**
* 启动流程实例,设置流程变量中的flag=0触发错误结束事件
*/
@Test
public void startProcessInstanceByKey() throws Exception{
// 设置对应的流程变量的值
Map<String,Object> map = new HashMap<>();
map.put("flag",0);// 设置flag为0触发流程结束事件
processEngine.getRuntimeService()
.startProcessInstanceById("event2005:1:ebec87e2-b028-11ec-b93f-c03c59ad2248",map);
System.out.println("开始启动的时间：" + LocalDateTime.now().toString());
// 需要在此阻塞比等待长的时间
TimeUnit.MINUTES.sleep(3);
}
看控制台输出
控制台输出的结果和我们预期的是一样的
说明错误结束事件的作用就是在执行到错误结束的节点位置会抛出对应的错误，供需要获取的事件来处理。
2.中断结束事件
中断结束事件也称为终止结束事件，主要是对流程进行终止的事件，可以在一个复杂的流程中，如果某方想要提前中断这个流程，可以采用这个事件来处理，可以在并行处理任务中。如果你是在流程实例层处理，整个流程都会被中断，如果是在子流程中使用，那么当前作用和作用域内的所有的内部流程都会被终止。具体还是通过两个案例来给大家介绍：
2.1 案例一
案例一我们介绍没有子流程的情况下终止的场景，具体案例如下

流程定义说明：并行网关中3个人工审核任务，分别分配的用户为zhangsan lisi wangwu ，然后在wangwu审核后会进入一个排他网关，如果flag是小于等于0就会触发终止结束事件。
<sequenceFlow id="sid-89945688-1D51-4391-A713-3E77ADB2FA06" sourceRef="p001" targetRef="stop001">
<conditionExpression xsi:type="tFormalExpression"><![CDATA[${flag<=0}]]></conditionExpression>
</sequenceFlow>
具体操作：部署流程–>启动流程实例–>wanwu 处理任务【流程实例 flag <= 0】 触发任务
@Test
public void test02() throws Exception{
Deployment deployment = processEngine.getRepositoryService().createDeployment()
.addClasspathResource("终止流程1.bpmn20.xml")
.name("终止流程1")
.deploy();
System.out.println("-----");
}
启动流程实例
@Test
public void startProcessInstanceByKey() throws Exception{
// 设置对应的流程变量的值
Map<String,Object> map = new HashMap<>();
map.put("flag",0);// 设置flag为0触发流程结束事件
processEngine.getRuntimeService()
.startProcessInstanceById("event3001:1:8b1663fa-b02d-11ec-b480-c03c59ad2248",map);
}
这时可以看到三个并行的Task任务：
这时我们只需王五来处理即可，在上一步中我们已经对流程变量赋值了
@Test
public void completeTask(){
TaskService taskService = processEngine.getTaskService();
Task task = taskService.createTaskQuery()
.processDefinitionId("event3001:1:8b1663fa-b02d-11ec-b480-c03c59ad2248")
.taskAssignee("wangwu")
.singleResult();
taskService.complete(task.getId());
}
然后再去看Task表中已经没有另外两条记录了哦
通过案例可以看到在没有子流程的情况下，终止结束事件会把整个流程都进程都结束了，而且在历史记录中也可以看到信息
2.2 案例二
然后我们来看看在子流程中触发终止结束事件的案例：

流程说明：人工任务一 –>zhangsan 人工任务二 –>lisi 子人工任务一 ：user1 子人工任务二 ：user2
子任务完成任务如果flag<=0,那么子流程中断结束，子人工任务二不会触发
部署流程
@Test
public void test02() throws Exception{
Deployment deployment = processEngine.getRepositoryService().createDeployment()
.addClasspathResource("终止流程2.bpmn20.xml")
.name("终止流程2")
.deploy();
System.out.println("-----");
}
然后启动流程
@Test
public void startProcessInstanceByKey() throws Exception{
// 设置对应的流程变量的值
Map<String,Object> map = new HashMap<>();
map.put("flag",0);// 设置flag为0触发流程结束事件
processEngine.getRuntimeService()
.startProcessInstanceById("event3002:1:92679bec-b03d-11ec-901e-c03c59ad2248",map);
}
这时在ACT_RU_TASK中就应该有三条对应的TASK记录了
然后我们执行user1的子任务，因为现在流程变量flag=0所以会触发终止结束事件
执行任务：
@Test
public void completeTask(){
TaskService taskService = processEngine.getTaskService();
Task task = taskService.createTaskQuery()
.processDefinitionId("event3002:1:92679bec-b03d-11ec-901e-c03c59ad2248")
.taskAssignee("user1")
.singleResult();
taskService.complete(task.getId());
}
执行成功后我们可以发现子人工任务一没有了，但是也没有子人工任务二，但是主流程中的两个任务都还在
而且进入到历史数据中也可以看到
3.取消结束事件
取消结束事件（cancel end event）只能与BPMN事务子流程（BPMN transaction subprocess）一起使用。当到达取消结束事件时，会抛出取消事件，且必须由取消边界事件（cancel boundary event）捕获。取消边界事件将取消事务，并触发补偿（compensation）。
具体通过案例来讲解：
结束取消事件我们只能在事务子流程中使用，在FlowableUI中暂时没有找到这个组件，所以在Eclipse中来绘制

流程说明：流程中定义了一个事务子流程和两个自动任务
然后在事务子流程中定义了两个人工任务用一个排他网关连接，flag<=0 的情况下会触发 取消结束事件
触发取消结束事件后同时会被取消边界事件捕获而走 取消事件结束的自动任务
同时自动补偿任务也会触发，关联的自动任务也会触发
注意在设置的时候需要设置补偿自动任务为可补偿的
补偿自动任务绑定的JavaDelegate：
public class MyOneDelegate implements JavaDelegate {
@Override
public void execute(DelegateExecution execution) {
System.out.println("完成自动审批任务-----》MyOneDelegate" + LocalDateTime.now().toString());
}
}
正常结束任务绑定的JavaDelegate:
public class MyTwoDelegate implements JavaDelegate {
@Override
public void execute(DelegateExecution execution) {
System.out.println("MyTwoDelegate---->执行了" + LocalDateTime.now().toString());
}
}
取消事件结束绑定的JavaDelegate
public class MyThreeDelegate implements JavaDelegate {
@Override
public void execute(DelegateExecution execution) {
System.out.println("MyThreeDelegate---->执行了" + LocalDateTime.now().toString());
}
}
然后我们部署，启动，和执行流程，看输出情况
/**
* 部署流程
* @throws Exception
*/
@Test
public void deploy() throws Exception{
Deployment deployment = processEngine.getRepositoryService().createDeployment()
.addClasspathResource("取消结束事件.bpmn20.xml")
.name("取消结束事件")
.deploy();
System.out.println("-----");
}
/**
* 启动流程实例,设置流程变量中的flag=0触发取消结束事件
*/
@Test
public void startProcessInstanceByKey() throws Exception{
// 设置对应的流程变量的值
Map<String,Object> map = new HashMap<>();
map.put("flag",0);// 设置flag为0触发流程结束事件
processEngine.getRuntimeService()
.startProcessInstanceById("myProcess:3:effb46cf-b168-11ec-926f-c03c59ad2248",map);
}
/**
* 完成任务
*/
@Test
public void completeTask(){
TaskService taskService = processEngine.getTaskService();
Task task = taskService.createTaskQuery()
.processDefinitionId("myProcess:3:effb46cf-b168-11ec-926f-c03c59ad2248")
.taskAssignee("zhangsan")
.singleResult();
taskService.complete(task.getId());
}
输出结果：
输出结果是满足我们的期望的。
4.补偿事件
通过补偿达到控制业务流程的目的就是补偿事件，比如我们正常的买机票的流程下订单购买，然后同时弹出支付流程页面。支付成功后就可以等待出票了，但是如果我们支付失败的话，这时要么重新支付，更换支付方式或者取消预订，这时取消预订我们就可以通过补偿事件来实现，具体的案例如下：

流程说明：
微信支付绑定的JavaDelegate：
public class MyOneDelegate implements JavaDelegate {
@Override
public void execute(DelegateExecution execution) {
System.out.println("微信支付-----》MyOneDelegate" + LocalDateTime.now().toString());
System.out.println("余额不足....");
throw new BpmnError("payFail");
}
}
预订机票绑定的JavaDelegate
public class MyTwoDelegate implements JavaDelegate {
@Override
public void execute(DelegateExecution execution) {
System.out.println("MyTwoDelegate---->预订机票流程执行了" + LocalDateTime.now().toString());
}
}
取消订单绑定的javaDelegate:
public class MyThreeDelegate implements JavaDelegate {
@Override
public void execute(DelegateExecution execution) {
System.out.println("MyThreeDelegate---->机票预订取消了...." + LocalDateTime.now().toString());
}
}
整个流程执行的过程是：任务开始后会并行的执行机票预订和微信支付，然后在微信支付是抛出payFail错误，同时错误边界事件会捕获到这个错误，然后执行到 补偿抛出中间事件，之后在机票预订的 补偿边界事件 被触发，对应的补偿触发器会执行对应的代码。然后我们部署加启动流程后观察控制台的输出：
/**
* 部署流程
* @throws Exception
*/
@Test
public void deploy() throws Exception{
Deployment deployment = processEngine.getRepositoryService().createDeployment()
.addClasspathResource("补偿事件.bpmn20.xml")
.name("补偿事件")
.deploy();
}
/**
* 启动流程实例
*/
@Test
public void startProcessInstanceByKey() throws Exception{
processEngine.getRuntimeService()
.startProcessInstanceById("myProcess:4:a45abe9f-b1b5-11ec-9daf-c03c59ad2248");
}
控制台输出：
MyTwoDelegate---->预订机票流程执行了2022-04-01T20:17:44.985
微信支付-----》MyOneDelegate2022-04-01T20:17:44.987
余额不足....
MyThreeDelegate---->机票预订取消了....2022-04-01T20:17:45.028
输出的结果和我们前面设计的是一样的，搞定~
