Spring 中，对象销毁前执行某些处理的方法

通过 @PreDestroy 和 bean 中配置 destroy-method 实现该功能

java 代码中：

   1: public class TestClass {

   2:     private ScheduledExecutorService scheduledExecutorService = Executors.newScheduledThreadPool(1);

   3:     public TestClass() {

   4:         scheduledExecutorService.scheduleAtFixedRate(task1, 1, 5, TimeUnit.MINUTES);

   5:     }

   6:  

   7:     Runnable task1 = new Runnable() {

   8:         public void run() {

   9:             System.out.println("task1 excuted.");

  10:         }

  11:     }

  12:  

  13:     @PreDestroy

  14:     public void DestroyMethod() {

  15:         scheduledExecutorService.shutdownNow();

  16:     }

  17: }

bean 配置文件中：

   1: <beans xmlns="http://www.springframework.org/schema/beans"

   2:     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"

   3:     xmlns:tx="http://www.springframework.org/schema/tx" xmlns:task="http://www.springframework.org/schema/task"
