WebCallerRunsPolicy策略:如果添加到线程池失败,那么主线程会自己去执行该任务,不会等待线程池中的线程去执行。 executor.setRejectedExecutionHandler(new RejectedExecutionHandler { @Override public void rejectedExecution (Runnable r, ThreadPoolExecutor executor) { // 拒绝策略的逻辑} }); 复制代码 WebThe following examples show how to use org.springframework.scheduling.concurrent.threadpooltaskexecutor#setCorePoolSize() .You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source file by following the links above each example.
面试官:说说你知道多少种线程池拒绝策略 - 掘金
WebCallerRunsPolicy:由主线程自己来执行这个任务,该机制将减慢新任务的提交; 关于 corePoolSize 与 maxPoolSize 的区别也是困惑了我很久,官方文档上的解释说的很清楚。我的理解如下: 这个线程池其实是有点“弹性的”。当向线程池提交任务时: WebJan 8, 2024 · CallerRunsPolicy 策略:只要线程池未关闭,该策略直接在调用者线程中,运行当前的被丢弃的任务。 biomutant automaton health injector empty
Java ThreadPoolExecutor的拒绝策略CallerRunsPolicy的一个潜在 …
Web(1)CallerRunsPolicy. Under this policy, the run method of the rejected task is directly executed in the caller thread, unless the thread pool has been shut down, the task is discarded directly. (2)AbortPolicy. Under this policy, the task is discarded directly and a RejectedExecutionException is thrown. (3)DiscardPolicy Webprefacio. Este blog resumirá Java multithreading basado en el conocimiento existente. El siguiente blog es solo un resumen del proceso de aprendizaje personal. Web虽然使用CallerRunsPolicy不会造成卡死,但是还是要慎重,如果导致主线程被大量阻塞,对业务同样有影响。 线程池不允许使用Executors去创建,而是通过ThreadPoolExecutor的方式,这样的处理方式让写的同学更加明确线程池的运行规则,规避资源耗尽的风险。 daily textile news
