Question

我是Spring MVC中的新手，我在Spring MVC项目中遇到以下问题，该项目使用FreeMarker作为我的观点。

我发现在尝试导入一些资源时遇到了一些问题（CSS文件和定义到我项目的myProject\src\main\webapp\resources\目录中的图像）。

所以我有这个header.ftl文件代表我所有页面的标题：

<!DOCTYPE html>
<!--[if IE 8]><html class="no-js is-ie8"><![endif]-->
<!--[if gt IE 8]><!--><html class="no-js"><!--<![endif]-->
    <head>
        <meta charset="utf-8">
        <meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">
        <meta name="viewport" content="width=device-width, initial-scale=1">
        <title>MY WEBSITE</title>
        <meta name="robots" content="noindex,nofollow">

        <link rel="stylesheet" href="resources/css/webfont.css">
        <link rel="stylesheet" href="resources/bootstrap/css/bootstrap.min.css">
        <link rel="stylesheet" href="resources/bootstrap/css/bootstrap-theme.min.css">
        <link rel="stylesheet" href="resources/plugins/bs-select/bootstrap-select.min.css">
        <link rel="stylesheet" href="resources/plugins/bs-dialog/bootstrap-dialog.min.css">
        <link rel="stylesheet" href="resources/css/style.css" />

</head>

<body id="main">
    <div class="container page-header">
        <h1>My WebSite</h1>
    </div>

因此，正如您所看到的，我将一些定义到myProject\src\main\webapp\resources\目录的css资源导入到我的项目中。

问题是我的项目中没有导入这些资源（所以我没有CSS设置）。

这是以前查看FirFox生成的HTML代码的CSS资源的渲染输出：

    <link rel="stylesheet" href="resources/css/webfont.css">
    <link rel="stylesheet" href="resources/bootstrap/css/bootstrap.min.css">
    <link rel="stylesheet" href="resources/bootstrap/css/bootstrap-theme.min.css">
    <link rel="stylesheet" href="resources/plugins/bs-select/bootstrap-select.min.css">
    <link rel="stylesheet" href="resources/plugins/bs-dialog/bootstrap-dialog.min.css">
    <link rel="stylesheet" href="resources/css/style.css" />

此项目中唯一的Spring xml配置文件名为 web-context.xml （这是 FreeMarker 的配置位置，其中指定了我的控制器的组件扫描），这一个：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <context:property-placeholder location="classpath*:*.properties"
        ignore-resource-not-found="true" />

    <!-- Controller -->
    <context:component-scan base-package="it.istruzione.iam.ssum.registrazione">
    </context:component-scan>

    <!-- Handles HTTP GET requests for /resources/** by efficiently serving up static resources in the ${webappRoot}/resources directory -->
    <mvc:resources mapping="/resources/**" location="/resources/" />

    <!-- Configurazione del resolver FreeMarker -->
    <!-- freemarker config -->
    <bean id="freemarkerConfig"
        class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">
        <property name="templateLoaderPath" value="/WEB-INF/freemarker/" />
    </bean>

    <bean id="viewResolver"
        class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver">
        <property name="cache" value="true" />
        <property name="prefix" value="" />
        <property name="suffix" value=".ftl" />
    </bean>

    <!-- Configurazione MVC -->
    <mvc:annotation-driven />

</beans>

如您所见，我已添加此行以尝试处理对/resources/目录内容的请求：

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

但它仍然无法正常工作，我无法访问位于/resources/子目录中的CSS资源。

当我将上一页显示到浏览器中时，在Eclipse控制台中，我获得了以下与这些资源相关的错误消息：

为什么呢？怎么了？我错过了什么？我该如何解决这个问题？

您可以使用JSTL`来确保您的网址正确无误：

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<link href="<c:url value="/resources/css/webfont.css" />" rel="stylesheet">

修改抱歉，我没有注意到它是一个freemarker页面：

<#import "/spring.ftl" as spring />

<link href="<@spring.url '/resources/css/webfont.css'/>" rel="stylesheet">

为什么我无法访问此Spring MVC应用程序的\ webapp \ resources \文件夹中定义的CSS资源？
