Question

我试图使用Spring MVC创建一个简单的JAVA Web应用程序。我试图在我的资源文件夹中添加CSS和JS文件，分别位于/Webcontents/resources/ and webcontents/JS。因此，我需要在servlet.xm l中进行一些配置，并在此文件中包含spring-webmvc。我的servlet.xml如下所示：

＆＃13;

<?xml version="1.0" encoding="UTF-8"?>
<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-4.3.xsd
        http://www.springframework.org/schema/mvc 
        http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd
        http://www.springframework.org/schema/context 
        http://www.springframework.org/schema/context/spring-context-4.3.xsd">
 
	<context:component-scan base-package="com.webrtc.controller" />

	<bean id="viewResolver"
		class="org.springframework.web.servlet.view.UrlBasedViewResolver">
		<property name="viewClass"
			value="org.springframework.web.servlet.view.JstlView" />
		<property name="prefix" value="/WEB-INF/jsp/" />
		<property name="suffix" value=".jsp" />
		<mvc:resources mapping="/resources/**" location="/resources/" />
		<mvc:resources mapping="/js/**" location="/js/" />
        <mvc:annotation-driven />
	</bean>
 
</beans>

＆＃13;

我的POM.xml如下：

一旦我使用Maven构建项目并尝试使用在Eclipse IDE上添加的Tomcat在服务器上运行它，我就会遇到以下错误：

我的其他配置如下：

Windows 10

Eclipse IDE

Spring 4.3.7

JAVA SDK 1.8

Tomcat 8.5

我尝试了不同的解决方案来解决版本问题，更改servlet.xml文件等但无法解决问题的问题。

任何人都知道如何解决这个问题？

任何帮助或建议都将受到高度赞赏！如果您需要有关项目的更多详细信息，我将能够为您提供更多详细信息。

Answer 1

我的servlet.xml如下所示

配置/WEB-INF/webrtc-servlet.xml有错误。要么删除这个文件或修复那里的错误。

这些元素应该在bean定义之外

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