springboot 优雅关闭

应用：停机升级服务时，若仍有线程运行，可等待一段时间后关闭应用；若线程未执行完成关闭应用，输出相应提示

**************************

示例

*********************

config 层

GracefulShutDown

@Component
public class GracefulShutDown implements TomcatConnectorCustomizer,ApplicationListener<ContextClosedEvent> {private Logger logger= LoggerFactory.getLogger(GracefulShutDown.class);private Connector connector;@Overridepublic void customize(Connector connector) {this.connector=connector;}@Overridepublic void onApplicationEvent(ContextClosedEvent contextClosedEvent) {  //容器关闭之前调用this.connector.pause();Executor executor=this.connector.getProtocolHandler().getExecutor();if (executor instanceof ThreadPoolExecutor){ThreadPoolExecutor threadPoolExecutor=(ThreadPoolExecutor) executor;threadPoolExecutor.shutdown();  //若无线程运行，立即关闭线程池；若有线程运行则等待try {if (!threadPoolExecutor.awaitTermination(10, TimeUnit.SECONDS)){//等待10s，为false表示线程池没有关闭，随后强制关闭，此时正在执行的任务中断，只执行了一部分，控制台输出warn日志logger.warn("10秒后线程未关闭，将强制关闭");}else {System.out.println("线程池已关闭："+ LocalDateTime.now());}                           //为true，线程池已经关闭，任务执行完成}catch (Exception e){e.printStackTrace();}}}
}

*********************

controller 层

HelloController

@RestController
public class HelloController {@RequestMapping("/hello")public String hello(){try{Thread.sleep(2000);}catch (Exception e){System.out.println(e.getMessage());}return "hello world";}@RequestMapping("/hello2")public String hello2(){try{Thread.sleep(20000);}catch (Exception e){System.out.println(e.getMessage());}return "hello world";}
}
