AbstractApplicationContext vs ApplicationContext

问题描述

AbstractApplicationContext 和 ApplicationContext 之间有什么区别？
我们可以打电话

what is the difference between AbstractApplicationContext and ApplicationContext ?can we call

context.registerShutdownHook()

使用 ApplicationContext ？

我看到了这一点浏览示例代码 -

I saw this while going through a sample code -

public static void main(String[] args) {
    AbstractApplicationContext context =new ClassPathXmlApplicationContext("Beans.xml");
    context.registerShutdownHook();
}

推荐答案

与摘要之间的差异相同class（AbstractApplicationContext）和接口（ApplicationContext）。

Same as the diff between abstract class (AbstractApplicationContext ) and an interface (ApplicationContext).

我们可以使用ApplicationContext调用context.registerShutdownHook（）吗？

不，因为 registerShutdownHook（）是 ConfigurableApplicationContext 接口的一部分，该接口未扩展通过 ApplicationContext

No, because registerShutdownHook() is part of ConfigurableApplicationContext interface which is not extended by ApplicationContext
