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：

public class TestClass {
    private ScheduledExecutorService scheduledExecutorService = Executors.newScheduledThreadPool(1);
    public TestClass() {
        scheduledExecutorService.scheduleAtFixedRate(task1, 1, 5, TimeUnit.MINUTES);
    }

    Runnable task1 = new Runnable() {
        public void run() {
            System.out.println("task1 excuted.");
        }
    }

    @PreDestroy
    public void DestroyMethod() {
        scheduledExecutorService.shutdownNow();
    }
}

bean 配置文件中：

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"
    xmlns:tx="http://www.springframework.org/schema/tx" xmlns:task="http://www.springframework.org/schema/task"
