异步线程

    @Bean("taskModuleExecutor")
    Executor getCrawler1(){
        ThreadPoolTaskExecutor threadPoolTaskExecutor = new ThreadPoolTaskExecutor();
        threadPoolTaskExecutor.setCorePoolSize(3);
        threadPoolTaskExecutor.setMaxPoolSize(10);
        threadPoolTaskExecutor.setQueueCapacity(200);
        threadPoolTaskExecutor.setThreadNamePrefix("task-concurrent-work");
       // threadPoolTaskExecutor.setRejectedExecutionHandler(new ThreadPoolExecutor.CallerRunsPolicy());
        threadPoolTaskExecutor.initialize();
        return threadPoolTaskExecutor;
    }

@Async("taskModuleExecutor")
public void asyncTest（）{
//加上Async表示基于主线程，新开一个线程。
单元测试中遇到主线程完成，但是子线程没有完成，会被中断，服务发布启动不会有这种情况，验证测试可以注释掉@Async("taskModuleExecutor")，看子线程是否会被中断
}

@EnableAsync
public class ServiceBootstrap(){
}
