} catch (SchedulerException e) {

}
}下发任务后，每次都会执行任务都会执行两次

Answer 1

你的quartz应该没问题
如果你是用Tomcat,问题应该是出现在Tomcat的部署上面
你的工程在tomcat配置有两个Host,就相当于你启动了两个定时任务
看下这篇文章，希望对你有用

Answer 2

 <Host name="localhost"  appBase=""
            unpackWARs="true" autoDeploy="true"
            xmlValidation="false" xmlNamespaceAware="false">
没有啊，我把appBase改了webapps下边的项目就没办法加载了

Answer 3

你看你src下 有没有quartz_job.xml和quartz.properties这两个文件，你是在程序中定义的Scheduler，有可能在这个quartz_job.xml中重复定义了
