如何配置spring的web.xml

我是spring的新手，並且在通過web.xml鏈接/配置springframework時遇到問題。運行我的應用程序時出現以下錯誤。如何配置spring的web.xml

錯誤：

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

顯然，它找不到在圖書館類org.springframework.web.servlet.DispatcherServlet。但是，我不知道如何告訴web.xml在哪裏尋找這個類。

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

您必須添加spring-webmvc.jar到CLASSPATH（最有可能/WEB-INF/lib目錄）。剩下的配置看起來很好。

添加到目錄中，現在獲取HTTP狀態500 - 組織/ springframework/context/EnvironmentAware -------------------------- -------------------------------------------------- ---- 類型異常報告消息組織/ springframework的/上下文/ EnvironmentAware 描述服務器遇到阻止其完成此請求一個內部錯誤（組織/ springframework的/上下文/ EnvironmentAware）。 – Muhammad

@Muhammad：確保你所有的Spring JAR文件都在同一個版本，並且你的CLASSPATH上也有'spring-context.jar'。 –

感謝Tomasz，我添加了spring-context.jar（對所有jar文件使用相同的版本），現在又抱怨HTTP Status 500-org/springframework/beans/factory/Aware。請你能建議是否有完整的jar文件列表，用於spring mvc項目？ – Muhammad
