从camunda UserTask钩子事件

Question

我想像本文所描述的那样从UserTask中挂钩事件：https://docs.camunda.org/manual/latest/user-guide/spring-boot-integration/the-spring-event-bridge/

我的听众：

@Component
@Slf4j
public class MyListener {
    public MyListener() {
        log.debug("[MyListener] create");
    }

    @EventListener
    public void onTaskEvent(DelegateTask taskDelegate) {
        log.debug("[DelegateTask] id" + taskDelegate.getId());
    }

    @EventListener
    public void onTaskEvent(TaskEvent taskEvent) {
        log.debug("[TaskEvent] id" + taskEvent.getId());
    }
}

我添加了属性：

camunda.bpm.eventing.execution=true
camunda.bpm.eventing.history=true
camunda.bpm.eventing.task=true

    <dependency>
        <groupId>org.camunda.bpm.springboot</groupId>
        <artifactId>camunda-bpm-spring-boot-starter</artifactId>
        <version>${camunda.spring.version}</version>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-jdbc</artifactId>
        <version>${springboot.version}</version>
    </dependency>
    ....
    and other

谢了。

您是否检查了Spring类路径扫描是否正确地拾取并注册了@component？如果监听器实现不小心没有放在Spring Boot Application类下面的包层次结构中，那么它将不会自动注册。

你是怎么测试的？Spring组件只有在运行SpringBootTest时才会被选中。使用@Rule ProcessEngineRule的普通Java测试是不够的。

如果正确地检测到组件（并且正确地发布了新属性），那么您应该能够观察到@EventListener方法被调用（例如，设置一个断点，并检查调试器是否在此停止）。
