Java多线程实践

1、定义一个线程类，通过HTTP接口推送通知

public class PushNoticeThread extends Thread {
    private String uid;
    private String number;
    private String noticeUrl;

    public PushNoticeThread(String uid, String number, String noticeUrl) {
        super();
        this.uid = uid;
        this.number = number;
        this.noticeUrl = noticeUrl;
    }

    @Override
    public void run() {
        // 推送通知
        String url = MessageFormat.format(noticeUrl, new Object[] { uid, number });
        HttpClient httpClient = new DefaultHttpClient();
        HttpGet httpGet = new HttpGet(url);
        try {
            httpClient.execute(httpGet);
        } catch (ClientProtocolException e) {
            LOGGER.error("e", e);
        } catch (IOException e) {
            LOGGER.error("e", e);
        }
    }
}

2、在Servcie里面调用该线程类，多线程执行该服务

 

private ExecutorService pushPool = Executors.newFixedThreadPool(200);
public void pushNotice(String uids, String noticeUrl) {
　　　　Thread pushThread = new PushNoticeThread(uids, beMentNums, noticeUrl);
       pushPool.execute(pushThread);
}

 

说明：定义的线程池大小为200，线程池来执行通知推送服务。
