同学好，感觉同学还有部分复用了最终代码的，但是却是第二章代码的配置，Caused by: org.springframework.beans.factory.BeanDefinitionStoreException: Invalid bean definition with name 'dataSource' defined in class path resource [spring/spring-dao.xml]: Could not resolve placeholder 'jdbc.url' in value

说的是'jdbc.url'没有赋值。。这个也是后面的内容，后面会以jdbc.properties里面的内容替换spring-dao.xml里面的内容，后面会做加密！

已发，如果按照视频来配置不会有这些问题的，其他同学都没有这样的问题。。
