您可能已经有一个 war 文件但不知道它 - netbeans 为您完成了大部分工作，我相信它会创建一个可分发的 war 文件默认情况下.如果您创建了一个 Web 项目并成功构建了它，它将位于项目根目录下的dist"目录中.

It's possible that you already have a war file and don't know it - netbeans does most of the work for you and I believe it creates a distributable war file by default. If you created a web project and successfully built it, it will be in the "dist" directory off your project root.
