1.6.1.6. Shutting Down the Spring IoC Container Gracefully in Non-Web Applications 在非web应用程序优雅地关闭Spring IoC容器

If you use Spring’s IoC container in a non-web application environment (for example, in a rich client desktop environment), register a shutdown hook with the JVM. Doing so ensures a graceful shutdown and calls the relevant destroy methods on your singleton beans so that all resources are released. You must still configure and implement these destroy callbacks correctly.

To register a shutdown hook, call the registerShutdownHook()  method that is declared on the ConfigurableApplicationContext interface, as the following example shows:

如果在非web应用程序环境中（例如，在富客户端桌面环境中）使用Spring的IoC容器，请向JVM注册一个关闭钩子（shutdown hook）。这样做可以确保正常shutdown，并在单例bean上调用相关的destroy方法，从而释放所有资源。您仍然必须正确配置和实现这些销毁回调。

要注册关闭钩子（shutdown hook），请调用ConfigurableApplicationContext 接口上声明的registerShutdownHook()  方法，如下例所示：

Java

import org.springframework.context.ConfigurableApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public final class Boot {

    public static void main(final String[] args) throws Exception {
        ConfigurableApplicationContext ctx = new ClassPathXmlApplicationContext("beans.xml");

        // add a shutdown hook for the above context...
        ctx.registerShutdownHook() ;

        // app runs here...

        // main method exits, hook is called prior to the app shutting down...
    }
}

Kotlin

import org.springframework.context.support.ClassPathXmlApplicationContext

fun main()  {
    val ctx = ClassPathXmlApplicationContext("beans.xml")

    // add a shutdown hook for the above context...
    ctx.registerShutdownHook() 

    // app runs here...

    // main method exits, hook is called prior to the app shutting down...
}
