ExecutorService线程池的使用

直接来实例：

 

    	ExecutorService executor = Executors.newFixedThreadPool(Constants.POOL_SIZE); //Constants.POOL_SIZE为开启多少线程比如20
    	
    	for(FcInfo fcInfo : fcInfos){
    		RemoteFileGetter fileGetter = new SPZRemoteFileGetter();
    		fileGetter.setIp(fcInfo.getIp());
    		fileGetter.setPort(fcInfo.getPort());
    		fileGetter.setPath(fcInfo.getRemotePath());
    		fileGetter.setDev_id(fcInfo.getDev_id());
    		fileGetter.setDev_name(fcInfo.getDev_name());
    		fileGetter.setDate(fcInfo.getDate());
    		executor.execute(fileGetter);//把fileGetter 加入线程池，记得fileGetter 要有run();方法
    	}
    	executor.shutdown();//关闭线程池

 

 

注：类位置：import java.util.concurrent.ExecutorService

Constants.POOL_SIZE的大小设计有没啥讲究的？
