ThreadPoolExecutor:JDK内置线程池实现 ThreadPoolTaskExecutor:Spring对JDK中线程池做了一层封装 参考代码:https://github.com/...*/ @Override public Executor getAsyncExecutor() { ThreadPoolTaskExecutor threadPoolTaskExecutor...= new ThreadPoolTaskExecutor(); //设置核心线程数,最大线程数,队列容量,线程存活时间 threadPoolTaskExecutor.setCorePoolSize...()); threadPoolTaskExecutor.setQueueCapacity(asyncThreadPoolConfig.getQueueCapacity());...(true); threadPoolTaskExecutor.initialize(); return threadPoolTaskExecutor; } } 创建一个测试类
ThreadPoolTaskExecutor学习 1.1....前言 我们知道一般创建线程池,我们都用ThreadPoolExecutor,但实际上Spring它也对该线程池做了一层封装,他就是ThreadPoolTaskExecutor 1.2....public static void main(String[] args) throws ExecutionException, InterruptedException { ThreadPoolTaskExecutor...executor = new ThreadPoolTaskExecutor(); executor.setCorePoolSize(1); executor.setMaxPoolSize...hello mytask-1 hello mytask-2 hello mytask-3 hello mytask-4 runnable runnable result [INFO] ThreadPoolTaskExecutor
initRedisPool(){ ThreadPoolTaskExecutor threadPoolTaskExecutor = new ThreadPoolTaskExecutor(...); /** * 核心线程数 */ threadPoolTaskExecutor.setCorePoolSize(4);.../** * 最大线程数 */ threadPoolTaskExecutor.setMaxPoolSize(9); /**...* 存活 */ threadPoolTaskExecutor.setKeepAliveSeconds(10 * 60); /** *...*/ threadPoolTaskExecutor.setThreadNamePrefix("redisThread" + "-"); /** * 拒绝策略
之前工作中发现有同事在使用线程池的时候经常搞混淆ThreadPoolTaskExecutor和ThreadPoolExecutor,座椅在这里想写一片博客来讲讲这两个线程池的区别以及使用 ThreadPoolExecutor...2.ThreadPoolTaskExecutor 这个类则是spring包下的,是sring为我们提供的线程池类,这里重点讲解这个类的用法,可以使用基于xml配置的方式创建 <bean id="taskExecutor" class="org.springframework.scheduling.concurrent.<em>ThreadPoolTaskExecutor</em>...taskExecutor; // 或者可以直接@Autowried @AutoWired <em>ThreadPoolTaskExecutor</em> taskExecutor 或者是通过配置类的方式配置线程池,然后注入...executor = new <em>ThreadPoolTaskExecutor</em>(); int i = Runtime.getRuntime().availableProcessors();
taskExecutor = new ThreadPoolTaskExecutor(); //设置线程池参数信息 taskExecutor.setCorePoolSize...taskExecutor = new ThreadPoolTaskExecutor(); //设置线程池参数信息 taskExecutor.setCorePoolSize...taskExecutor = new ThreadPoolTaskExecutor(); //设置线程池参数信息 taskExecutor.setCorePoolSize...") public ThreadPoolTaskExecutor threadPoolTaskExecutor() { ThreadPoolTaskExecutor executor...= new ThreadPoolTaskExecutor(); executor.setCorePoolSize(5); executor.setMaxPoolSize

我们为何使用多线程,之前已经有讲过了,为了更快的处理多个任务,分割任务,或者调用多个毫无关联的第三方服务 其实spring就提供了ThreadPoolTaskExecutor这个类来实现线程池,线程池是啥
Spring Framework 提供了一个强大的线程池实现,即org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor。...阻塞队列的种类 ThreadPoolTaskExecutor使用一个阻塞队列来存储等待执行的任务。...ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor(); executor.setCorePoolSize(10); executor.setMaxPoolSize...ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor(); executor.setCorePoolSize(5); executor.setMaxPoolSize...结语 ThreadPoolTaskExecutor是Spring框架中强大的线程池实现,通过合理选择阻塞队列类型,我们可以更好地满足应用程序的需求,提高性能和稳定性。
