Question

我试图通过更改AdmissionForm.jsp文件中h3标记的内容来提供一些主题多重支持的主页，但是在点击红色或绿色链接后我遇到了问题，我收到以下警告：< / p>

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>

</body>
</html>

Answer 1

资源不应该存在于WEB-INF下，因为servlet容器绝不能直接从那里提供任何服务。在将调度程序servlet映射到/而不是/*时，可以直接由tomcat为WEB-INF外部的资源提供服务。

直接在WebContent下将css文件移动一级。

Answer 2

根据您的堆栈跟踪，没有任何控制器映射来为您的资源提供服务。您需要添加mvc:resources标记才能为静态资源配置处理程序。

作为建议，不要将静态资源保留在WEB-INF文件夹中，而是在WebContent目录下创建一个子文件夹，并将其命名为资源或静态资源，因为稍后您可能想要添加一个全新的servlet处理资源请求。

此外，我还要添加一个拦截器，以防您想要将静态资源保留在浏览器的缓存中。只需将其添加到<mvc:interceptors>部分即可。

                          <!--  Dont Keep It Under WEB-INF -->
<mvc:resources mapping="/static-resources/**" location="/WEB-INF/static-resources/"/>

<mvc:interceptors>
  <mvc:interceptor>
    <mvc:mapping path="/static-resources/**" />
       <bean id="webContentInterceptor" class="org.springframework.web.servlet.mvc.WebContentInterceptor">
<!--                cache will expire the next Year(365 days) -->
                <property name="cacheSeconds" value="31556926" />
                <property name="useExpiresHeader" value="true" />
                <property name="useCacheControlHeader" value="true" />
                <property name="useCacheControlNoStore" value="true" />
        </bean>
     </mvc:interceptor>
</mvc:interceptors>

在DispatcherServlet中找不到带有URI [/FirstSpringMVCProject/stylegreen.css]的HTTP请求的映射，其名称为＆＃39; spring-dispatcher＆＃39;
