如何配置spring的web.xml

我是spring的新手，并且在通过web.xml链接/配置springframework时遇到问题。运行我的应用程序时出现以下错误。如何配置spring的web.xml

错误：

HTTP Status 500 - Error instantiating servlet class org.springframework.web.servlet.DispatcherServlet 


    type Exception report 

    message Error instantiating servlet class org.springframework.web.servlet.DispatcherServlet

显然，它找不到在图书馆类org.springframework.web.servlet.DispatcherServlet。但是，我不知道如何告诉web.xml在哪里寻找这个类。

的web.xml

<?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"> 

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

     <servlet-mapping> 
      <servlet-name>DispatcherSample</servlet-name> 
      <url-pattern>/PlayField.html</url-pattern> 
     </servlet-mapping> 

     <welcome-file-list> 
     <welcome-file>index.html</welcome-file> 
     <welcome-file>Welcome.html</welcome-file> 
     </welcome-file-list> 

    </web-app>

DispatcherSample-servlet.xml中

<?xml version="1.0" encoding="UTF-8"?> 

    <beans xmlns="http://www.springframework.org/schema/beans" 
     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/context http://www.springframework.org/schema/context/spring-context.xsd"> 

     <bean id="handlerMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping"> 
      <property name="mappings"> 
       <props> 
        <prop key="/PlayField.html">playfieldController</prop> 
       </props>  
      </property> 
     </bean> 

     <bean id="playfieldController" class="demos.PlayfieldController"/> 

    </beans>

java.lang.ClassNotFoundException: org.springframework.web.servlet.DispatcherServlet

您必须添加spring-webmvc.jar到CLASSPATH（最有可能/WEB-INF/lib目录）。剩下的配置看起来很好。

添加到目录中，现在获取HTTP状态500 - 组织/ springframework/context/EnvironmentAware -------------------------- -------------------------------------------------- ---- 类型异常报告消息组织/ springframework的/上下文/ EnvironmentAware 描述服务器遇到阻止其完成此请求一个内部错误（组织/ springframework的/上下文/ EnvironmentAware）。 – Muhammad

@Muhammad：确保你所有的Spring JAR文件都在同一个版本，并且你的CLASSPATH上也有'spring-context.jar'。 –

感谢Tomasz，我添加了spring-context.jar（对所有jar文件使用相同的版本），现在又抱怨HTTP Status 500-org/springframework/beans/factory/Aware。请你能建议是否有完整的jar文件列表，用于spring mvc项目？ – Muhammad
