Question

我是Apache camel和quartz调度程序的新手。我试图在集成中使用它们但无法做到。我在“Camel in Action”一书中找到了一篇小文章但我没有设法运行该程序 - 这是我的代码

package com.cockpitconfig.schedulars;

import org.apache.camel.CamelContext;
import org.apache.camel.builder.RouteBuilder;
import org.apache.camel.impl.DefaultCamelContext;

public class TestScheduler {

    public static void main(String args[]) throws Exception {
        CamelContext context = new DefaultCamelContext();
        context.disableJMX();
        context.addRoutes(new RouteBuilder() {
            @Override
            public void configure() {
                from(
                        "quartz://myTimer?trigger.repeatInterval=2000&trigger.repeatCount=-1")
                        .setBody().simple("Current time is ").to("stream:out");
            }
        });

        context.start();
        Thread.sleep(10000);

        context.stop();
    }
}

但是它给出了错误

有人能解决这个问题吗？

Answer 1

你正在使用哪种版本的Camel？使用2.8-SNAPSHOT它对我来说很好。确保你的路径中有骆驼核心，骆驼石英和骆驼流依赖。

Answer 2

目前的camel-quartz插件文档并不明显，但是从Camel 2.11.0开始，它只与Quartz 1.x兼容，并且与Quartz 2.x（已经存在了几年）不兼容因为Quartz 2.x与Spring 3.0不兼容（而且Camel已经表示它现在将保持Spring 3.0的兼容性。

这在this Camel JIRA issue上有记录。
