springboot中@Aysnc的线程池设置

1、添加AsyncConfig配置类，设置线程池信息

@Configuration
@EnableAsync
public class AsyncConfig implements AsyncConfigurer {

    public static final Logger logger = LoggerFactory.getLogger(AsyncConfig.class);


    /**
     *  线程数量未达到corePoolSize，则新建一个线程(核心线程)执行任务
     *  线程数量达到了corePools，则将任务移入队列等待
     *  队列已满，新建线程(非核心线程)执行任务
     *  队列已满，总线程数又达到了maximumPoolSize，就会抛出异常
     *
     * @param
     * @Return: java.util.concurrent.Executor
     * @Author: niuqingsong

     */
    @Override
    public Executor getAsyncExecutor() {
        ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
        /*核心线程数，如果当前运行的线程数小于corePoolSize，那么就创建线程来执行任务*/
        executor.setCorePoolSize(10);
        /*最大线程数*/
        executor.setMaxPoolSize(30);
        /*队列大小*/
        executor.setQueueCapacity(8);
        executor.initialize();
        executor.setThreadNamePrefix("AsyncThread-");
        logger.info("init async thread pool");
        return executor;
    }

    @Override
    public AsyncUncaughtExceptionHandler getAsyncUncaughtExceptionHandler() {
        return null;
    }
}
