線程基本介紹和創(chuàng)建方式

參考Java 多線程編程

jdk自帶的線程池

java.util.concurrent包提供了線程相關(guān)的類，ThreadPoolExecutor用于創(chuàng)建一個線程池，通常我們會這樣創(chuàng)建一個線程池

private ThreadPoolExecutor scheduleExecutor =
            new ThreadPoolExecutor(100, 100, 0, TimeUnit.MILLISECONDS, new ArrayBlockingQueue<>(100),
                    new NamedThreadFactory("basic-data"), new LoggerDiscardPolicy());

spring的線程池

spring的線程池是對ThreadPoolExecutor的封裝

@Configuration
public class ThreadPoolConfig {
    @Bean("threadPoolTaskExecutor")
    public ThreadPoolTaskExecutor threadPoolTaskExecutor(){
        ThreadPoolTaskExecutor threadPoolTaskExecutor=new ThreadPoolTaskExecutor();
        threadPoolTaskExecutor.setCorePoolSize(4);
        threadPoolTaskExecutor.setKeepAliveSeconds(10);
        threadPoolTaskExecutor.setMaxPoolSize(10);
        threadPoolTaskExecutor.setQueueCapacity(10);
        return threadPoolTaskExecutor;

    }
}
