找不到類[org.apache.commons.dbcp.BasicDataSource]

我在嘗試啓動Spring MVC hibernate應用程序時遇到此異常。找不到類[org.apache.commons.dbcp.BasicDataSource]

SEVERE: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener 
org.springframework.beans.factory.CannotLoadBeanClassException: Cannot find class [org.apache.commons.dbcp.BasicDataSource] for bean with name 'dataSource' defined in ServletContext resource [/WEB-INF/spring/appServlet/mysql_persistence_info.xml]; nested exception is java.lang.ClassNotFoundException: org.apache.commons.dbcp.BasicDataSource 
    at org.springframework.beans.factory.support.AbstractBeanFactory.resolveBeanClass(AbstractBeanFactory.java:1235)

我/WEB-INF/spring/appServlet/mysql_persistence_info.xml是

我在classapath所需的所有jar文件。我正在使用STS。

我有commons-dbcp.jar和所有其餘的jar文件。

只有在STS/eclipse classpath中有jar文件是不夠的 - 它們應該放在web-inf \ lib文件夾中 - 如果你試圖將它作爲webapp運行。 – gkamal

對於STS，我不知道web-inf/lib路徑在哪裏。我查看了Web應用程序目錄，並且沒有web-inf/lib文件夾。 – djoshi
