Question

我尝试在以下bpd中抛出并捕获名为“alert”的信号，如activiti userguide中所述。但是我无法触发附加到信号捕获事件的服务事件。

我尝试通过java

触发信号

runtimeService.signalEventReceived("alert");

但没有发现信号。下面的代码确保有一个监听器附加了进程启动

List<Execution> executions = runtimeService.createExecutionQuery()
                  .signalEventSubscriptionName("alert")
                  .list();

在下面附上完整的bpd：

我在这里做错了吗？我尝试将catch事件放入和转出子进程，以检查是否由于任何范围问题导致此问题。仍然没有运气。真的卡在这里。

Answer 1

您无法在同一过程中创建signal throwing event和signal catching event。它没有任何意义，一个进程如何同时抛出并捕获同一个事件。要么将您的流程划分为两个单独的流程，要么至少将其中一个流程划分为子流程。

Answer 2

您的流程根据定义是错误的。您必须在事件子流程内使用信号START事件或在子流程上使用边界事件。没有序列流，就无法触发中间捕获事件。为清晰起见，您还应使用信号结束事件，而不是中间投掷事件。

将您的流程模型更改为：
