ThreadPoolExecutor的簡單實踐

1. 創建

//創建阻塞隊列
BlockingQueue<Runnable> queue = new LinkedBlockingQueue<Runnable>();
//創建線程池
ThreadPoolExecutor executorService = new ThreadPoolExecutor(8, 8, 5, TimeUnit.MINUTES, queue, (runnbale) -> {
            Thread t = new Thread(runnbale);
            t.setName("自定義線程");
            t.setDaemon(true);
            return t;
        });
//預啓動所有核心線程        
executorService.prestartAllCoreThreads();

2. 使用

executorService.execute(() -> {
	try {
	             log.info("OrderDataBizServiceImpl.procurementOrderHandler 開始");
	             procurementOrderHandler(applyData);
	             log.info("OrderDataBizServiceImpl.procurementOrderHandler 完成");
	         } catch (Exception e) {
	             log.error("OrderDataBizServiceImpl.procurementOrderHandler 異常", e);
	         } finally {
	             countDownLatch.countDown();
	         }
	     });
