ThreadPoolExecutor是Java中线程池的实现类,Executors工具类中有多个它的工厂方法(newFixedThreadPool等),本身池的思想是享元模式的应用,这里实际上JDK通过ThreadPoolExecutor使得客户端代码和Thread解耦,我们不需要再直接控制Thread的了(ThreadPoolExecutor可以通过设置ThreadFactory定制Thread)。另外这里使用的设计模式有: 1、...
, summing them up in the reduce call. this simple example may not demonstrate the full usefulness of using a custom thread pool, but the benefits become obvious in situations where we do not want to tie-up the common thread pool with long-running tasks – such as processing data from a ...
