ThreadPoolExecutor 执行任务的时候会执行两遍

Question

public void run() {
SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
System.out.println("获取新闻任务开始时间："
+ df.format(Calendar.getInstance().getTime()));
ThreadPoolExecutor threadpool = new ThreadPoolExecutor(
corePoolSize, maximumPoolSize, consumeTaskSleepTime,
TimeUnit.SECONDS, new ArrayBlockingQueue<Runnable>(
ArrayBlockingQueueSize));
try {
List<NewsRule> rules = newsRuleService.getNewsRule();
if(rules!=null&&rules.size()>0){
threadpool.execute(new CrawlNewsThreadNew(rules));
}
} catch (Exception e) {
log.error(e.getMessage(),e);
}finally{
System.out.println("获取新闻任务结束时间："
+ df.format(Calendar.getInstance().getTime()));
}

}
求解释这是什么情况！！！

最终问题解决了～是tomcat初始化的时候的问题因为设置了虚拟路径
<Host name="localhost"  appBase=""
            unpackWARs="true" autoDeploy="true"
            xmlValidation="false" xmlNamespaceAware="false">        <!-- SingleSignOn valve, share authentication between web applications
             Documentation at: /docs/config/valve.html -->
        <!--
        <Valve className="org.apache.catalina.authenticator.SingleSignOn" />
        -->        <!-- Access log processes all example.
             Documentation at: /docs/config/valve.html -->
        <!--
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"  
               prefix="localhost_access_log." suffix=".txt" pattern="common" resolveHosts="false"/>
        -->
         <Context path="" docBase="webapps/你的项目名" />
      </Host>改成这样就好了
