问题描述

我有一个非常简单的web应用程序，我尝试使用 flot javascript库绘制图形.我的JSP文件是按以下方式导入所需的* .js文件的.

I have a very simple webapp where I am trying to plot graphs using flot javascript library. My JSP file goes this way where I am importing the required *.js files as follows.

相对于WEB-INF/pages/hello.jsp中的hello.jsp文件，具有相关.js文件的脚本目录位于../../scripts(即直接位于ROOT下)

Relative to the hello.jsp file at WEB-INF/pages/hello.jsp, scripts directory with the relevant .js files are at ../../scripts (i.e. directly under ROOT)

目录结构如下 root @ domU-12-31-39-13-C5-F5:/usr/local/jetty/webapps#树

Directory structure is as follows root@domU-12-31-39-13-C5-F5:/usr/local/jetty/webapps# tree

观察

  1. 使用Firefox蚀，我可以看到浏览器正在请求 GET
  1. Using firefox eclipse, I can see that browser is requesting for GET http://ec2-184-73-14-57.compute-1.amazonaws.com:5809/scripts/jquery.flot.js but unable to find it hence fails with 404 Not found
  2. Moving the scripts directory to under WEB-INF and changing the relative paths is also resulting in the same error.
  3. Similar application deployed in tomcat is picking .js files from ROOT directory when referenced as /scripts/*.js
  4. Unable to reference the js files using absolute path and when I do, it tries to append the absolute path to http://ec2-184-73-14-57.compute-1.amazonaws.com:5809/ and trying to fetch it .. thus resulting in 404 error

以前从未使用过Jetty，这个问题是Jetty特有的吗?有什么更好的导入javascript文件的方法.请指教

Never used Jetty before, is this problem specific to Jetty? What is a better way to import javascript files. Please advice

这是webapp启动后的转储

推荐答案

您的servlet-mapping设置不正确.

名为mvc-dispatcher的servlet是在"/"的url-pattern处设置的，也称为servlet规范默认servlet路径规范. Web容器本身提供的一些功能使其可以提供静态内容(例如CSS和javascript文件).

The servlet named mvc-dispatcher is setup at url-pattern of "/", also known as the servlet spec default servlet path spec. Something that the web container itself provides to allow it to serve static content (like css and javascript files).

mvc-dispatcher位于"/"，这意味着默认Servlet本身不能提供静态内容.

With your mvc-dispatcher at "/" that means the Default Servlet itself cannot serve static content.

这也意味着org.springframework.web.servlet.DispatcherServlet现在负责提供来自WebApp的所有内容.这是一个非典型的servlet-mapping，我怀疑这就是spring DispatcherServlet的作用.

That also means that org.springframework.web.servlet.DispatcherServlet is now responsible for serving all content from the WebApp. This is an atypical servlet-mapping and I doubt that's the role of the spring DispatcherServlet.

考虑使用基于后缀的servlet路径规范(例如"*.html")或基于前缀的servlet路径规范(例如"/*")(在Servlet规范的第12节中对此进行了概述)

Consider using a suffix based servlet path spec like "*.html" or a prefix based servlet path spec like "/*" (this is outlined in the Section 12 of the Servlet Spec)
