我没有用spring mvc抓住我的javascript文件

Question

我有一个使用spring 2.5.6开发的应用程序网站。但我的javascript文件有问题，因为我的应用程序没有捕获这些文件。我不和他们合作，而且我做的更多，我找不到解决方案。

这是我的结构

src
   java
      controller
   test
   resource
   static
      js
        files.js
   WEB_INF
      pages
      spring
      lib 
      web.xml

这些是我的档案 的web.xml

Answer 1

我相信你的问题是你将所有请求“/”映射到调度程序servlet。没有用于处理资源网址的控制器，因此您可能会从spring获得错误，因为它无法将网址映射到控制器。

如果您使用的是spring 3，那么您可以将此行添加到servlet上下文中。

<mvc:resources mapping="/resources/**" location="/resources/" />

这假设您的所有资源都位于名为“resources”的文件夹中，该文件夹位于WebRoot文件夹中，而不是WEB-INF！如果你使用maven那么它将是/ src / main / webapp / resources。不要将资源放在WEB-INF中，这是一个隐藏客户端内容的私有文件夹。如果您通过控制器显示JSP，则只能将JSP放在WEB-INF中，控制器可以看到此文件夹但客户端/浏览器不能。

你遇到了问题，因为你使用的是不支持资源标签的旧版spring。我认为您需要做的是将资源的servlet映射覆盖到默认的servlet而不是spring front controller。

像这样的东西。

<servlet-mapping>
  <servlet-name>default</servlet-name>
  <url-pattern>/resources/*</url-pattern>
</servlet-mapping>

<servlet-mapping>
  <servlet-name>spring-mvc-dispatcher</servlet-name>
  <url-pattern>/</url-pattern>
</servlet-mapping>

这假定与另一个示例具有相同的文件夹结构。您可以调整自己项目结构的映射，但只记得它应该在WebRoot而不是WEB-INF中。

Answer 2

静态文件（css，js，..）不能保留在WEB-INF文件夹中。它们应该公开供浏览器阅读。拿出来
