在方法中开启子线程

 public void scienceArchive(List<FinishedFile> list) throws Exception {
    
    
	 System.out.println("主线程开始。。。。。");
	 
	//开启子线程
 ThreadFactory scanerThreadFactory = new ThreadFactoryBuilder()
                    .setNameFormat("子-%d").build();
            ExecutorService scanerThreadPool = new ThreadPoolExecutor(2, 2,
                    0L, TimeUnit.MILLISECONDS,
                    new LinkedBlockingQueue<Runnable>(1024), scanerThreadFactory, new ThreadPoolExecutor.AbortPolicy());
            scanerThreadPool.execute(() -> {
    
    
                System.out.println("子线成:开始"+Thread.currentThread().getName());
                for (VolumeFile v : volumeFileList) {
    
    
                    try {
    
    
                        this.settingSearchFile(v);
                    } catch (Exception e) {
    
    
                        log.error(String.format("scienceArchive-设置全文检索，时间：%s，参数：%s,异常信息：%s",new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(new Date()),v.getId(),e.toString()));

                    }
                }
                System.out.println("子线成结束:"+Thread.currentThread().getName());

            });

	 System.out.println("主线程结束。。。。。");
 }

主线程执行完成,子线程可以慢慢执行
