控制台在Java中终止时如何生成一些事件？

分类：编程问答

如何解决控制台在Java中终止时如何生成一些事件？

我正在使用java.enter代码中的硒库进行爬网

是登录->移动页面->输入的搜索关键字->爬行数据表

我将源文件设为jar-> exe。

我的源代码以无头模式执行chromedriver。

无论如何，我在Eclipse中执行了exe或.java文件。 当我单击exe中的“ X”按钮或单击控制台（Eclipse）中的红色按钮（终止）时

背景chromedriver和Google chrome无法关闭。

如何关闭后台chromedriver？

我认为我的动作就像关闭主要方法，而不是异常关闭 （因为当我输入ctrl + z时：它正确运行，因此背景chromedriver已关闭。）

这是我的消息来源...我需要您的帮助：
