CannotLoadBeanClassException: 找不到 class [org.springframework.jdbc.datasource.DriverManagerDataSource]
CannotLoadBeanClassException: Cannot find class [org.springframework.jdbc.datasource.DriverManagerDataSource]
我正在开发 Maven spring mvc 应用程序。我在pom.xml中添加了依赖，并在servlet-context.xml中给出了引用。请参考以下：
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:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-jdbc</artifactId>
<version>3.1.1.RELEASE</version>
</dependency>
但是当我 运行 项目时，我仍然遇到这个异常。不知道为什么。需要一些帮助。
