无法在 spring-servlet.xml 文件中创建 org.apache.commons.dbcp.BasicDa

Question

我正在创建一个带有休眠集成的 spring-mvc 项目。我添加了包含 BasicDataSource.class 的 commons-dbcp 1.4 jar 文件，当我尝试在我的 spring-servlet 中创建它的 bean.xml 文件时，它给了我以下错误：

例外是java.lang.ClassNotFoundException：

org.apache.commons.dbcp.BasicDataSource

我的 spring-servlet.xml 文件中的代码：
