1定義單例設計模式
public class ThreadPoolManager {
private ExecutorService service;
private ThreadPoolManager(){
int num = Runtime.getRuntime().availableProcessors(); //擷取目前系統的CPU數目
service = Executors.newFixedThreadPool(num*2);//ExecutorService 通常根據系統資源情況靈活定義線程池大小。
}
private static final ThreadPoolManager manager= new ThreadPoolManager();
public static ThreadPoolManager getInstance(){
return manager;
public void addTask(Runnable runnable){
service.execute(runnable);
}
2 調用
private ThreadPoolManager threadPoolManager;
threadPoolManager = ThreadPoolManager.getInstance();
3 生成
BaseTask taskThread = new BaseTask() //線程類--擷取資料
this.threadPoolManager.addTask(taskThread);//将建立的現成添加入線程池
歲月裡，寒暑交替。人世間，北來南往。銘心的，雲煙的。都付往事，不念，不問。
