How to serve static content from tomcat
提问by
I have a directory containing a number of static file (*.png, *.css, etc).
I thought (mistakenly perhaps) that just creating a directory in my application's WEB-INF file would suffice and I would be able to access the files by just referring to them by name:
Ex:
我有一个包含许多静态文件（*.png、*.css 等）的目录。
我认为（可能是错误的）只需在我的应用程序的 WEB-INF 文件中创建一个目录就足够了，我只需按名称引用它们就可以访问这些文件：
例如：
<link rel="stylesheet" href="/static/styles.css" type="text/css">
My directory structure is as follows:
我的目录结构如下：
+WEB-INF
|
+---static
|
+--styles.css
+--header.png
My web.xml is as follows
我的web.xml如下

There are three means to configure Wickets configuration mode and they are
tested in the order given.
1) A system property: -Dwicket.configuration
2) servlet specific <init-param>
3) context specific <context-param>
The value might be either "development" (reloading when templates change)
or "deployment". If no configuration is found, "development" is the default.

But....
This doesn't work I just get a 404 - file not found when attempting to access the resources contained in the "static" directory. Is there something I'm missing here?
但是....
这不起作用我只是在尝试访问“静态”目录中包含的资源时得到一个 404 - 未找到文件。有什么我在这里想念的吗？

Don't put them into WEB-INF, that folder is for the stuff that you do notwant to have directly served.
不要把它们放到WEB-INF，该文件夹是东西，你不希望有直接投放。
Put it next to WEB-INF
把它放在 WEB-INF 旁边
+- WEB-INF
+- static

The files should not be inside WEB-INF. They must be placed directly inside your web-applications directory or WAR file.
这些文件不应位于 WEB-INF 中。它们必须直接放置在您的 web-applications 目录或 WAR 文件中。
Look at my answer herefor including the context path before your static resources.
回答by Robby Pond
WEB-INF is a protected directory. They must be placed in or in a subdirectory in the top level web app directory.
WEB-INF 是受保护的目录。它们必须放置在顶级 Web 应用程序目录的子目录中或子目录中。
