多线程

线程基本介绍和创建方式

参考Java 多线程编程

jdk自带的线程池

java.util.concurrent包提供了线程相关的类，ThreadPoolExecutor用于创建一个线程池，通常我们会这样创建一个线程池

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

spring的线程池

spring的线程池是对ThreadPoolExecutor的封装

@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;

    }
}
