Error creating bean with name 'test' defined in class path resource [connection.xml]: Cannot resolve reference to bean 'dataSource' while setting bean property 'dataSource'; nested exception is org.springframework.beans.factory.CannotLoadBeanClassException: Cannot find class
connection.xml里面用test这个id定义的bean没有找到，看看你这个bean的路径和名字对不对。

dataSource配置的class有错误
