上面代码中的 ExecutorExample 只能在Java 5.0 下运行,如果用 Spring 的 TaskExecutor 替换①处的 Executor,当程序需部署到低版本的 Java 环境中时,仅需要选择一个合适的实现就可以了。 publicclassExecutorExample {privateTaskExecutor executor;//①使用Spring的TaskExecutor替换Java 5.0的ExecutorpublicvoidsetExecutor(...

Executor框架是指java 5中引入的一系列并发库中与executor相关的一些功能类,其中包括线程池,Executor,Executors,ExecutorService,CompletionService,Future,Callable等。 类关系图如下: 在Executor框架中,使用执行器(Exectuor)来管理Thread对象,从而简化了并发编程。
JavaConcurrencyInPractice-线程池的使用 1、摘要 线程池的使用使得任务的提交与执行解耦开来,但是,线程池可以执行所有任务吗? 答案是——不能,线程池中封装了任务的执行策略,提供了几种执行策略的实现, 但是,不是所有的任务都能由这些策略来执行的: 1、依赖性任务,任务的执行依赖其他任务。
you can use constructions of the form * result = exec.submit(aCallable).get(); * * Note: The {@link Executors} class includes a set of methods * that can convert some other common closure-like objects, * for example, {@link java.security.PrivilegedAction} to * {@link Callable} for...
