/WEB-INF/classes 与/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/ 目录中与其他实用程序 jars 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.

两者在类加载、访问应用程序上下文等方面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，该索引与原始 url 相距数十次点击.有人知道那里发生了什么吗?

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

我会选择 /WEB-INF/classes.它允许您在调试模式下运行您的应用程序，并在更改时热插拔类.如果将所有内容都打包为 jar，则每次更改类时都必须重新打包和重新部署应用程序.

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.
