java - 无法删除 Camel Quartz 路线

Question

我设置了这样的端点:

from("quartz://GroupName/TimerName?stateful=true&cron=0 0/1 * * * ?")
.to("someProcessorBean");

为了确保没有静态端点，我这样做:

for (Endpoint endpoint : camelContext.getEndpoints()) {
  camelContext.removeEndpoint(endpoint);
}

当尝试以编程方式删除路线时，我正在执行以下操作:

camelContext.stop();
camelContext.removeRoute(routeId);

但是，此处没有返回端点。

即使执行此操作后，作业仍会继续按计划运行。删除路线时如何取消安排？

我使用的是camel-quartz 2.22.2和quartz 1.8.6

以下是 Context 关闭和启动的日志。

选项 1

升级到camel-quartz2而不是camel-quartz。

选项 2

该问题与 Quartz 组件创建两个调度程序有关，并且在停止路由时仅关闭一个调度程序。这可能是由于路由是有状态的。为了解决这个问题，您可以手动访问与该组件相关的所有调度程序并停止所有作业。

log.info("Removing existing endpoints");
for (Endpoint endpoint : camelContext.getEndpoints()) {
  log.info("Removing: " + endpoint.getEndpointUri());
    
  if (endpoint instanceof QuartzEndpoint) {
    QuartzEndpoint quartzEndpoint = (QuartzEndpoint) endpoint;
    
    SchedulerFactory factory = quartzEndpoint.getComponent().getFactory();
    log.debug("Found factory " + factory);
    
    @SuppressWarnings("unchecked")
    Collection<Scheduler> allSchedulers = factory.getAllSchedulers();
    for (Scheduler scheduler : allSchedulers) {
      log.debug("Found Quartz Scheduler" + scheduler.getSchedulerName());
      for (String groupName : scheduler.getJobGroupNames()) {
        for (String jobName : scheduler.getJobNames(groupName)) {
          log.debug(String.format("Unscheduling job %s.%s", groupName, jobName));
          scheduler.deleteJob(jobName, groupName);
        }
      }
    }
  }
  camelContext.removeEndpoint(endpoint);
}
    
log.info("Stopping Camel Context");
camelContext.stop();
    
log.info("Removing existing routes");
RoutesDefinition routes = getRouteCollection();
routes.getOnExceptions().clear();
for (RouteDefinition route : routes.getRoutes()) {
  String routeId = route.getId();
  try {
    log.info("Removing: " + routeId);
    camelContext.removeRoute(routeId);
  } catch (Exception e) {
    log.warn("Could not stop route" + routeId + ": " + e.getMessage());
  }
}
routes.getRoutes().clear();
