写在前面

子流程作为主流程的一部分存在，拥有独立的开始节点和结束节点，即可以单独作为一个完整的流程来使用，当一个流程比较复杂时，可以考虑使用子流程来进行包裹，下面来一起看下。

1：测试

1.1：流程设计

效果图

在这里插入图片描述

说明

子流程使用了错误结束节点，错误结束节点也是一种结束节点，只不过我们使用最多的是普通的结束节点，结束时静默结束，而错误结束节点是在结束时会抛出一个错误编码，如下时我们设置的要抛出的错误编码：

然后在子流程边界定义了一个错误边界事件 ,来捕获错误编码，让流程流转到主流程继续处理，如下是设置：

1.2：部署流程

@Test
public void deploy() {Deployment deployment = repositoryService.createDeployment() // 创建部署.addClasspathResource("com/jh/activiti/error_end_event.bpmn20.xml") // 加载流程资源文件.name("子流程中的错误结束节点测试") // 流程名称.deploy(); // 部署System.out.println("流程部署ID:" + deployment.getId());System.out.println("流程部署Name:" + deployment.getName());
}

1.3：启动流程实例

/*** 启动流程实例*/
@Test
public void start() throws InterruptedException {runtimeService.startProcessInstanceByKey("subProcessErrorEndEvent"); // 流程定义表的KEY字段值
}

此时生成子流程中服务执行节点对应的任务，如下：

在这里插入图片描述

1.4：完成任务子流程正常结束

@Test
public void completeSubProcessNoError() {// 测试子流程不以错误节点结束，即不会执行到外部流程/*Map<String, Object> paramsMap = new HashMap<>();paramsMap.put("flag", true);taskService.complete("662510", paramsMap);*/// 测试子流程以错误节点结束，会执行到外部流程Map<String, Object> paramsMap = new HashMap<>();paramsMap.put("flag", true);taskService.complete("1075010", paramsMap); // 执行子流程任务节点
//        taskService.complete("1070010"); // 被子流程的错误边界事件捕获，进入到外部任务阶段，完成外部任务节点
}

此时流程正常结束，不会流转到主流程：

在这里插入图片描述

1.5：完成任务子流程通过错误结束节点结束

@Test
public void completeSubProcessNoError() {// 测试子流程不以错误节点结束，即不会执行到外部流程/*Map<String, Object> paramsMap = new HashMap<>();paramsMap.put("flag", true);taskService.complete("662510", paramsMap);*/// 测试子流程以错误节点结束，会执行到外部流程Map<String, Object> paramsMap = new HashMap<>();paramsMap.put("flag", true);taskService.complete("1075010", paramsMap); // 执行子流程任务节点
//        taskService.complete("1070010"); // 被子流程的错误边界事件捕获，进入到外部任务阶段，完成外部任务节点
}
