java - Activiti - 继续执行而不完成子流程

Question

我们正在使用 Activiti 工作流引擎，我们想知道如果子流程未完成，是否可以继续执行流程。

例如，我们有一个子进程A和一个子进程B，如下所示，A->B。 A 有两个端节点，一个正在执行，另一个正在等待用户任务完成。所以我猜测子进程 A 尚未完成，但我们希望继续执行并启动 B。

问题是，我们正在寻找影响最小的解决方案，因为我们已经在生产中拥有庞大的工作流程，如果我们想要添加子流程的话。

在这种情况下你们有什么建议？流程/执行/任务变量在这种情况下如何工作？

编辑:我们现在正尝试像 Greg Harley - BP3 建议的那样开始这个测试用例，但中间的 catch 事件永远不会被调用。

Answer 1

不确定这是否是您想要的，但包含“the Dogs”任务的子流程只会在用户任务 2 完成后调用。在示例中，用户任务 2 是一个用户任务，但它也可以很容易地成为一个服务或脚本任务。这样，只要先决条件完成，子流程 2(包含狗)就会运行，无论用户任务 1 是否完成。

如果我错过了您的具体要求，请告诉我。格雷格
