創建線程池

用的單例懶單例創建的緩存線程池

---

package util.sup;

import java.util.concurrent.SynchronousQueue;
import java.util.concurrent.ThreadPoolExecutor;
import java.util.concurrent.TimeUnit;

public class ThreadPoolManager {

public final static ThreadPoolManager I = new ThreadPoolManager();

private ThreadPoolExecutor threadPoolExecutor;

public ThreadPoolExecutor getThreadPoolExecutor() {
    return threadPoolExecutor;
}

public ThreadPoolManager() {
    init();
}

private void init() {
    construteThreadPool();
}

// 獲取單例的線程池對象
private void construteThreadPool() {
    if (this.threadPoolExecutor == null) {
        synchronized (ThreadPoolManager.class) {
            if (this.threadPoolExecutor == null) {
                this.threadPoolExecutor = new ThreadPoolExecutor(0, Integer.MAX_VALUE, 60L, 
                    TimeUnit.SECONDS,new SynchronousQueue<Runnable>());
            }
        }
    }
}

}

使用的時候直接
ThreadPoolManager.I.getThreadPoolExecutor().execute(new InsertSmsDayTimeLineTask(null));

其中InsertSmsDayTimeLineTask就是你要跑的線程類了，當然構造函數自己隨意了

package stock.simulator.trader.web.task;

import java.util.List;

import stock.simulator.trader.web.data.SmsDayTimeLineDO;
import util.sup.ServiceBean;

public class InsertSmsDayTimeLineTask extends ServiceBean implements Runnable {

private List<SmsDayTimeLineDO> smsDayTimeLineList;

public InsertSmsDayTimeLineTask(List<SmsDayTimeLineDO> smsDayTimeLineList) {
    this.smsDayTimeLineList = smsDayTimeLineList;
}

@Override
public void run() {
    // 你想幹啥
}

}

ServiceBean 是用來做service引用的

package util.sup;

import stock.simulator.trader.web.ApplicationContextUtil;
import stock.simulator.trader.web.service.SmsMarketQuotationService;
import stock.simulator.trader.web.service.StockService;

public class ServiceBean {

public StockService getStockService() {
    return (StockService) ApplicationContextUtil.getBean("stockService");
}

public SmsMarketQuotationService getSmsMarketQuotationService() {
    return (SmsMarketQuotationService) ApplicationContextUtil.getBean("smsMarketQuotationService");
}

}

}
