Maven Spring mvc中的Oracle连接

我对Java Web非常陌生。我只是尝试在maven mvc上做一个简单的登录页面。但我有一个错误：

org.springframework.beans.factory.BeanCreationException: Error creating bean with 
name 'dataSource' defined in ServletContext resource 
[/WEB-INF/mvc-dispatcher-servlet.xml]: Error setting property values; nested 
exception is org.springframework.beans.PropertyBatchUpdateException; nested 
PropertyAccessExceptions (1) are: PropertyAccessException 1:
 org.springframework.beans.MethodInvocationException: Property 'driverClassName' 
threw exception; nested exception is java.lang.IllegalStateException: Could not 
load JDBC driver class [oracle.jdbc.OracleDriver] at 
org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.applyPropertyValues

Web.xml是：

<web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
      http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
     version="2.5">


<display-name>Archetype Created Web Application</display-name>

  <servlet>
    <servlet-name>mvc-dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
  </servlet>

  <servlet-mapping>
    <servlet-name>mvc-dispatcher</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>

  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/mvc-dispatcher-servlet.xml</param-value>
  </context-param>


  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
</web-app>

我知道我只是复制粘贴我所有的代码和它的脏活。对不起。但我需要学习使用oracle connection开发maven spring mvc项目。你的帮助将是宝贵的。我还想完成oracle表的示例工作。我真的搜索过谷歌，但没有太多。（所有这些例子都是mysql。当我尝试用oracle连接转换它们时，我也遇到了错误。我真的很累。）

感谢您将

ojdbc6.jar

放入ApacheTomcat安装目录中的

lib

目录中

d:\apache tomcat server\Tomcat 8.0\lib

它解决了我的问题。

为什么不将流程分块，而不是一次实现所有内容。您是否已将oracle库添加到此处提到的类路径中？
