blocks|key|349333|text|据我所知，正如你所说，"INF“代表”信息“。它可能被命名为WEB-INF，因为它与JAR文件中的META-INF目录相似。有时，随着时间的推移，目录的含义会发生很大变化，以至于它不再有意义。例如，Unix/Linux中的bin目录通常包含非二进制的“可执行”文件，如外壳脚本。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|349334|entityMap^0|U|7|1D|8|33|3|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]|$9|M|A|N|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|O|8|@]|D|@]|E|$]]]|G|$]]

As far as I know, "INF" stands for "Information", as you said. It probably was named <code>WEB-INF</code> for similarity with the <code>META-INF</code> directory in JAR files. Sometimes the meaning of a directory changes so much over time that it no longer makes sense. For example, <code>bin</code> directories in Unix/Linux often contain non-binary "executable" files, such as shell scripts.

blocks|key|3121736|text|我相信它实际上被命名为WEB-INF，以镜像包含元信息的jar文件中的META-INF目录。我明白你所说的关于可执行文件和“信息”一样多的意思，但主要的一点是它不包含应用程序的文档。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3121737|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I believe it's really named WEB-INF to mirror the META-INF directory in a jar file, which contains meta information. I do see what you mean about it being as much about executables as "information" but the main point is that it doesn't contain the documents of the application.

blocks|key|344559|text|我认为，唯一的逻辑定义是WEB-INF是META-INF的镜像。命名对于初学者来说真的很重要，如果它令人困惑，那么这个主题就会变得越来越难理解。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|344560|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I think, the only logical definition is WEB-INF is mirror of META-INF. Naming is really important for beginners and if it is confusing then the subject is getting harder to understand.

blocks|key|3121788|text|WEB_INF文件夹包含web.xml+(部署描述符)文件、类、外部库等，web.xml文件包含有关容器urls、文件等的信息，因此该文件夹称为WEB-INF。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|3121789|entityMap^0|0|7|C|7|11|7|20|7|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]|$9|M|A|N|B|C]|$9|O|A|P|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|Q|8|@]|D|@]|E|$]]]|G|$]]

The <code>WEB_INF</code> folder contains the <code>web.xml</code> (deployment descriptor) file, the classes, external libs etc and as <code>web.xml</code> file contains the information about the container urls, files etc, the folder is known as <code>WEB-INF</code>.

blocks|key|349374|text|它是一个存储私有应用程序内容的目录。你的应用程序需要但你的客户端不需要的任何东西都可以存储在那里。该目录中的任何内容对web都不可见。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|349375|来源：|349376|http://tomcat.apache.org/tomcat-7.0-doc/appdev/source.html#Directory_Structure+http://docs.oracle.com/cd/E13222_01/wls/docs70/webapp/basics.html#136976|offset|length|349377|entityMap|0|LINK|mutability|MUTABLE|url|http://tomcat.apache.org/tomcat-7.0-doc/appdev/source.html#Directory_Structure|1|http://docs.oracle.com/cd/E13222_01/wls/docs70/webapp/basics.html#136976^0|0|0|0|26|0|27|20|1|0^^$0|@$1|2|3|4|5|6|7|R|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|S|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|T|8|@]|9|@$F|U|G|V|1|W]|$F|X|G|Y|1|Z]]|A|$]]|$1|H|3|-4|5|6|7|10|8|@]|9|@]|A|$]]]|I|$J|$5|K|L|M|A|$N|O]]|P|$5|K|L|M|A|$N|Q]]]]

It's a directory to store private application content. Anything your app needs but your client doesn't can be stored there. Anything in that directory is not visible to the web.

Most of the places on the internet say it stands for WEB INFormation.

I rather doubt it. The folder contains executables. Information is not a suitable name for it.

What does WEB-INF stand for in a Java EE web application?

容器

Linux

Unix

互联网上的大多数地方都说它代表WEB INFormation。我对此表示怀疑。该文件夹包含可执行文件。信息不是一个合适的名称。
