从JDK5 开始提供Executor FrameWork(java.util.concurrent.*) 分离任务和创建和执行者的创建 线程重复利用(new线程代价很大) 理解共享线程池的概念 预设好的多个Thread, 可弹性增加 多次执行很多很小的任务 任务创建和执行过程解耦 程序猿无需关心线程池执行任务过程 Executor(2) 主要类: ExecutorService, ThreadPoolExec...
Executor Framework 包含一组用于有效管理多个线程的组件。 它与 JDK 5 一起发布,用于运行Runnable对象,而无需每次都创建新线程,并且主要重用已创建的线程。 这个Executor API 将任务的执行与要在 Executor 的帮助下执行的实际任务分离。 这以 Executor 接口及其子接口 ExecutorService 和类 ThreadPoolExecutor 为中心。
ExecutorService executor = Executors.newFixedThreadPool(NTHREDS); while(rs.next()){ webLink=rs.getString(1); FirstName=rs.getString(2); MiddleName=rs.getString(3); Runnable worker = new MyRunnable(webLink,FirstName,MiddleName);// this interface has run method... executor.execute(worker);...
Executor框架是在Java5中引入的,可以通过该框架来控制线程的启动,执行,关闭,简化并发编程。Executor框架把任务提交和执行解耦,要执行任务的人只需要把任务描述清楚提交即可,任务的执行提交人不需要去关心。 通过Executor框架来启动线程比使用Thread更好,更易管理,效率高,避免this逃逸问题。

Then some friends will ask, as a NIO framework, where is the multi-threading of netty reflected? What is the underlying principle of it? Today, let's take a look at the task executors EventExecutor and EventExecutorGroup in netty.
ThreadPoolExecutor:这个是JAVA自己实现的线程池执行类,基本上创建线程池都是通过这个类进行的创建! ThreadPoolTaskExecutor :这个是springboot基于ThreadPoolExecutor实现的一个线程池执行类。 In the absence of an Executor bean in the context,Spring Bootauto-configures a ThreadPoolTaskExecutor with sensible defaul...
