Answer 1

已经说的很明白了，找不到类nested exception is java.lang.ClassNotFoundException: org.apache.commons.dbcp.BasicDataSource

Answer 2

Cannot find class [org.apache.commons.dbcp.BasicDataSource] for bean with name 'dataSource' defined in class path resource [mySpring.xml]; nested exception is java.lang.ClassNotFoundException: org.apache.commons.dbcp.BasicDataSource
检查一下你的数据源的配置。

Answer 3

Caused by: java.lang.ClassNotFoundException: org.apache.commons.dbcp.BasicDataSource，我觉得是这样的：首先你选中BasicDataSource并复制，然后按：ctrl+shift+T，黏贴进去看看可能找到这个类，要是找不到的话，那么你就可以打开spring配置文件，然后ctrl+F黏贴进去找到这个类的配置，我觉得肯定是这个位置你字母写错了，

Answer 4

Caused by: java.lang.ClassNotFoundException: org.apache.commons.dbcp.BasicDataSource
