Java threadpoolmanages the pool of worker threads, it contains a queue that keeps tasks waiting to get executed. We can useThreadPoolExecutorto create thread pool in java. Java thread pool manages the collection of Runnable threads and worker threads execute Runnable from the queue.java.util.con...
ThreadPoolExecutorprovides several methods using which we can find out the current state of the executor, pool size, active thread count and task count. So I have a monitor thread that will print the executor information at a certain time interval. package com.journaldev.threadpool; import ...

这是 Java 里的一种异常，叫做 Spring Framework 的 `TaskRejectedException`，产生的原因是 Executor 没有接受到所赋予的任务。在你的错误报告中，这个 Executor 是一个 `ThreadPoolExecutor`，它的当前状态是运行中，线程池大小为 20，活动的线程数为 20，队列中的任务数为 30000，已完成的任务数为 22735。发生...
