java - 在名称为“spring-dispatcher”的DispatcherServlet中，未找到带有URI [/FirstSpringMVCProject/stylegreen.css]的HTTP请求的映射

我试图通过更改AdmissionForm.jsp文件中h3标记的内容来为某些主题的主页提供支持，但是单击红色或绿色链接后，我遇到了以下警告：

No mapping found for HTTP request with URI [/FirstSpringMVCProject/stylegreen.css] in DispatcherServlet with name 'spring-dispatcher'
or
No mapping found for HTTP request with URI [/FirstSpringMVCProject/stylered.css] in DispatcherServlet with name 'spring-dispatcher'

AdmissionForm.jsp文件中的一些代码

<%@taglib prefix="form" uri="http://www.springframework.org/tags/form" %>
<%@taglib prefix="spring" uri="http://www.springframework.org/tags" %>
<html>
<body>
<a href="/FirstSpringMVCProject/admissionForm.html?sitelanguage=en"> English </a> |
<a href="/FirstSpringMVCProject/admissionForm.html?sitelanguage=de"> German </a>

    <!--Added tut 27 for differnt themes -->
    <link rel="stylesheet" href="<spring:theme code='styleSheet'/>" type="text/css" />

    <p> <a href="/FirstSpringMVCProject/admissionForm.html?siteTheme=green">Green</a> |
        <a href="/FirstSpringMVCProject/admissionForm.html?siteTheme=red">Red</a> </p>

    <h1><spring:message code="label.headerMessage" /></h1>

    <h3> <spring:message code="label.admissionForm" /></h3>

最佳答案

资源不应存在于WEB-INF下，因为servlet容器绝不能直接从那里提供任何服务。当您将调度程序servlet映射到/而不是/*时，tomcat可以直接为WEB-INF之外的资源提供服务。

只需将CSS文件直接在WebContent下向上移动一个级别。
