Spring web.xml映射错误

-1

我最近开始使用Spring，现在我在映射中遇到错误。我检查了其他的解决方案，但没有为我工作，一些解决方案正在讨论maven，但因为我不知道maven可以解决这个错误没有maven。这是我的web.xml：Spring web.xml映射错误

<?xml version="1.0" encoding="UTF-8"?> 
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0"> 

    <display-name>FristSpringMvcProject</display-name> 


    <servlet> 
    <servlet-name>spring-dispatcher</servlet-name> 
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 
    </servlet> 

    <servlet-mapping> 
    <servlet-name>spring-dispatcher</servlet-name> 
    <url-pattern>/</url-pattern> 
    </servlet-mapping> 
</web-app>

我收到此错误：

description The server encountered an internal error() that prevented it from fulfilling this request.

正如你可以在堆栈跟踪看到：java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory apache的commons-logging.jar在您calsspath失踪。下载并将其添加到您的类路径中。

如果您正在使用maven添加以下的依赖：

<dependency> 
    <groupId>commons-logging</groupId> 
    <artifactId>commons-logging</artifactId> 
    <version>1.2</version> 
</dependency>
