java - css文件不适用于我的jsp（maven/spring/hibernate项目）

问题描述

我创建了一个小项目来填写表格（姓名+国家），并在验证后列出数据库中的表格。该项目是一个带有 maven 的 Web 应用程序。我集成了 spring + hibernate 来管理我的数据库。但是，我无法将我的 css 文件应用于 jsp，也无法显示图像。我不知道如何解决我的问题。

项目结构：

在 WEB-INF 中添加 spring-web-config.xml：

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xmlns:context="http://www.springframework.org/schema/context"

        <property name="suffix">

        </property>
    </bean>

    <mvc:resources mapping="/resources/**" location="/resources/"  />
    <mvc:annotation-driven />

</beans>

解决方案

我在您的代码中看不到任何资源映射配置。

您可以spring-web-config.xml在 WEB-INF 中添加以下内容

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="
        http://www.springframework.org/schema/beans     
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/mvc 
        http://www.springframework.org/schema/mvc/spring-mvc.xsd
        http://www.springframework.org/schema/context 
        http://www.springframework.org/schema/context/spring-context.xsd">

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


</beans>

来自这个 URL 模式的任何请求，Spring 都会从路径中/resources/**寻找资源。/resources/

在 JSP 中使用

<link href="<c:url value="/resources/css/main.css" />" rel="stylesheet">

or

<script src="<c:url value="/resources/js/main.js" />"></script>

请参阅此处了解更多详细信息

选项 2：

您可以尝试mvc:resource在现有的spring.xml
