Question

我试图在我的tomcat上显示一个简单的EXT JS表单，但是我收到以下错误：

17-Apr-2012 10:46:09 org.springframework.web.servlet.DispatcherServlet noHandlerFound
WARNING: No mapping found for HTTP request with URI [/helloworld/service/web/js  /restful.css] in DispatcherServlet with name 'rest'
17-Apr-2012 10:46:09 org.springframework.web.servlet.DispatcherServlet noHandlerFound
WARNING: No mapping found for HTTP request with URI [/helloworld/service/web/js/restful.js] in DispatcherServlet with name 'rest'

的web.xml

<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>

<!-- This listener will load other application context file in addition to 
        rest-servlet.xml -->
<listener>
<listener-class>

<servlet>
<servlet-name>rest</servlet-name>

</servlet>

<servlet-mapping>
<servlet-name>rest</servlet-name>

</web-app>

其余-servlet.xml中

    </property>

        <value>.jsp</value>
    </property>
</bean>

我从index.jsp

调用restful.css和restful.js类

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>

<%@ page contentType="text/html; charset=ISO-8859-1"%>

<html>

<head>
<link rel="stylesheet" type="text/css" href="/webapp/js/restful.css" />
<script type="text/javascript" src="/webapp/js/restful.js"></script>
</head>

<body>
<h1>This is used to display EXT objects</h1>
</body>

</html>

目录结构

this is the structure of my directory

我似乎无法解决这个错误，我的index.jsp正好出现在页面上但没有出现EXT表格，我已经在网上查看了类似的问题，目前所有解决方案都在我的解决方案中，所以这不一样错误。

有人有什么想法吗？

Answer 1

目前，您通过相对路径引用静态文件（.js和.css）。它没有意义，因为这些文件的位置不依赖于正在显示的页面的位置。

您需要使用绝对路径。您可以使用<c:url>构建包含应用程序上下文路径的绝对路径（因此，无论您的应用程序部署在何处，它们都是正确的）：

<link rel="stylesheet" type="text/css" href="<c:url value = '/js/restful.css' />" />
<script type="text/javascript" src="<c:url value = '/js/restful.js' />"></script>

Answer 2

试试这个..

<link rel="stylesheet" type="text/css" href="/js/restful.css" />
<script type="text/javascript" src="/js/restful.js"></script>
