带有优先级和超时设置的任务执行者，可以实现下列逻辑： 并行处理一堆任务，返回在指定时间内完成的任务结果 并行处理一堆任务，返回在优先级最高的（第一个）任务完成或超时之前完成的任务结果
public class PriorityTaskExecutor extends ThreadPoolExecutor {
public PriorityTaskExecutor(int corePoolSize, int maximumPoolSize, long keepAliveTime, TimeUnit unit, BlockingQueue<Runnable> workQueue) {
super(corePoolSize, maximumPoolSize, keepAliveTime, unit, workQueue);
}

long timeout, TimeUnit unit)
throws InterruptedException {
if (tasks == null || unit == null)

Raspberry Pi上听豆瓣电台的简易方法：sudo apt-get install mpg123 php5-cli，然后执行本程序即可
#!/usr/bin/env php
<?php
function fetch_page($url, $timeout = 5) {
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$data = curl_exec($ch);
curl_close($ch);
