本文整理了Java中org.apache.tomcat.util.threads.ThreadPoolExecutor类的一些代码示例，展示了ThreadPoolExecutor类的具体用法。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。ThreadPoolExecutor类的具体详情如下：
包路径：org.apache.tomcat.util.threads.ThreadPoolExecutor
类名称：ThreadPoolExecutor

ThreadPoolExecutor介绍

[英]Same as a java.util.concurrent.ThreadPoolExecutor but implements a much more efficient #getSubmittedCount() method, to be used to properly handle the work queue. If a RejectedExecutionHandler is not specified a default one will be configured and that one will always throw a RejectedExecutionException
[中]和java一样。util。同时发生的ThreadPoolExecutor，但实现了一个更高效的#getSubmittedCount（）方法，用于正确处理工作队列。如果未指定RejectedExecutionHandler，则将配置默认的处理程序，并且该处理程序将始终抛出RejectedExecutionException
