Apache Camel quartz2 计时器启动多个交换

Question

I have an application that creates routes to connect to a REST endpoint and process the responses for several vendors. Each route is triggered with a quartz2 timer. Recently when the timer fires it creates multiple exchanges instead of just one and I cannot determine what is causing it.

The method that creates the routes is here:

    public String generateRoute(String vendorId) {

        routeBuilders.add(new RouteBuilder() {
            @Override
            public void configure() throws Exception {
                System.out.println("Building REST input route for vendor " + vendorId);
                String vendorCron = vendorProps.getProperty(vendorId + ".rest.cron");
                String vendorEndpoint =  vendorProps.getProperty(vendorId + ".rest.endpoint");
                String vendorAuth = vendorProps.getProperty(vendorId + ".rest.auth");
                int vendorTimer = Integer.valueOf(vendorId) * 10000;
                GsonDataFormat format = new GsonDataFormat(RestResponse.class);
                from("quartz2://timer" + vendorId + "?cron=" + vendorCron)
                        .routeId("Rte-vendor" + vendorId)
                        .streamCaching()
                        .log("Starting route " + vendorId)
                        .setHeader("Authorization",constant(vendorAuth))
                        .to("rest:get:" + vendorEndpoint)
                        .to("direct:processRestResponse")
                        .end();

            };
        });
        return "direct:myRoute." + vendorId;

and a sample 'vendorCron' string is

"*+5+*+*+*+?&trigger.timeZone=America/New_York".

When the quartz route fires I see this type of output in the log

15:39| INFO | CamelLogger.java 159 | Starting route 4
15:39| INFO | CamelLogger.java 159 | Starting route 4
15:39| INFO | CamelLogger.java 159 | Starting route 4
15:39| INFO | CamelLogger.java 159 | Starting route 4
15:39| INFO | CamelLogger.java 159 | Starting route 4
15:39| INFO | CamelLogger.java 159 | Starting route 4
15:39| INFO | CamelLogger.java 159 | Starting route 4
15:39| INFO | CamelLogger.java 159 | Starting route 4
15:39| INFO | CamelLogger.java 159 | Starting route 4
15:39| INFO | CamelLogger.java 159 | Starting route 4

When I should ( and used to) only see one of these.

Any ideas what would cause this?

Thanks!

Answer 1

This is because of your vendorCron

• If Cron trigger is every 5secs then you see this log in every 5 secs..
• If Cron trigger is every 5mins/hours you see these login in 5 mins/hours.

Answer 2

I was staring so hard I missed the obvious. I need a 0 in the seconds place of the cron expression.

Thank you for the time.
