本文整理了Java中org.elasticsearch.threadpool.ThreadPool.generic()方法的一些代码示例，展示了ThreadPool.generic()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。ThreadPool.generic()方法的具体详情如下：
包路径：org.elasticsearch.threadpool.ThreadPool
类名称：ThreadPool
方法名：generic

ThreadPool.generic介绍

[英]Get the generic ExecutorService. This executor service Executor#execute(Runnable) method will run the Runnable it is given in the ThreadContext of the thread that queues it.

Warning: this ExecutorService will not throw RejectedExecutionExceptionif you submit a task while it shutdown. It will instead silently queue it and not run it.
[中]获取通用执行器服务。这个executor service executor#execute（Runnable）方法将运行Runnable，它是在队列线程的线程上下文中给出的。
警告：如果在任务关闭时提交任务，此ExecutorService将不会抛出RejectedExecutionException。相反，它将静默地对其排队，而不是运行它。

代码示例

/**
 * The executor service for this transport service.

 * @return the executor service
 */
private ExecutorService getExecutorService() {
  return threadPool.generic();
}
