[英]CannotLoadBeanClassException: Cannot find class [org.springframework.jdbc.datasource.DriverManagerDataSource]
问题描述
I am working on a Maven spring mvc application. 
我正在研究Maven spring mvc应用程序。 I have added the dependency in pom.xml and gave the reference in servlet-context.xml. 我在pom.xml中添加了依赖性，并在servlet-context.xml中给出了引用。 please refer below: 请参考以下内容：
servlet-context.xml: servlet-context.xml：
<beans:bean class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<beans:property name="driverClassName" value="oracle.jdbc.OracleDriver"/>
<beans:property name="url" value="jdbc:oracle:thin:@localhost:1521:ORCL"/>
<beans:property name="username" value="sysman"/>
<beans:property name="password" value="orcl"/>
</beans:bean>
pom.xml: pom.xml：
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-jdbc</artifactId>
<version>3.1.1.RELEASE</version>
</dependency>
But still I am getting this exception when i run the project. 但是，当我运行该项目时，仍然遇到此异常。 Not sure why. 不知道为什么。 Need some help please. 请需要帮助。

You are probably using incorrect dependency - Mostly looking into the maven central for the older version artifact and newer version of the artifact as well, there is no current version with 3.1.1.RELEASE existing. 您可能使用了不正确的依赖关系-大多数情况下，对于旧版本的工件和新版本的工件 ，他们都在maven中央进行查找，不存在具有3.1.1.RELEASE当前版本。 It might have been removed or never existed. 它可能已被删除或不存在。 So please use the updated version as - 因此，请使用更新的版本-
