/ WEB-INF / classes vs / WEB-INF / lib [英] /WEB-INF/classes vs /WEB-INF/lib

问题描述

我想将我的 Java EE6 Web类（bean，过滤器，servlet）打包到jar中并将其放入 / WEB-INF / lib / 目录以及其他实用程序jar并完全放弃 / WEB-INF / classes / 目录。

I'd like to package my Java EE6 web classes (beans, filters, servlets) into jar and place it into /WEB-INF/lib/ directory along with other utility jars and abandon /WEB-INF/classes/ directory totally.

在类加载，访问应用程序上下文等方面两者之间是否存在实质性差异？

Are there any substantial differences between the two in terms of classloading, acessing application context, etc?

谢谢。

PS：每当谷歌搜索任何java规范时，我总是被重定向到Oracle文档索引，这是远离原始URL的十几次点击。有谁知道那里发生了什么？

PS: Whenever googling any of java specs I'm always redirected to Oracle documentation index which is dozen clicks away from original url. Anyone knows what's happening there?

推荐答案

我要去 / WEB-INF / classes 。它允许您在调试模式下运行应用程序，在更改时运行热交换类。如果您将所有内容打包为jar，则每次更改类时都必须重新打包并重新部署应用程序。

I'd go for /WEB-INF/classes. It allows you to run your application in debug mode and hot-swap classes on change. If you package everything as a jar, you'd have to repackage and redeploy the app every time you change a class.
