无法在 spring-servlet.xml 文件中创建 org.apache.commons.dbcp.BasicDataSource 的 bean

Question

我正在创建一个带有休眠集成的 spring-mvc 项目。我添加了 commons-dbcp 1.4 jar 文件，其中包含 BasicDataSource.class，但当我尝试在我的 spring-servlet.xml 文件中创建它的 bean 时，它仍然给我以下错误：

例外是 java.lang.ClassNotFoundException:

org.apache.commons.dbcp.BasicDataSource

我的 spring-servlet.xml 文件中的代码：
