实际多线程例子
一、建立多线程入口bean
@Component public class CallFunction { @Autowired private BatchSendSMSService batchSendSMSService; @Autowired private SmsTransitService smsTransitService; public void smsThread(Map<String, Object> map){ ExecutorServiceUtil.newExecutorService().submit(new Runnable() { @Override public void run() { batchSendSMSService.batchSend(map); } }); } public void ymSmsThread(Map<String, Object> map){ ExecutorServiceUtil.newExecutorService().submit(new Runnable() { @Override public void run() { batchSendSMSService.yMbatchSend(map); } }); } }
二、Executor线程池框架专配类
