参考技术A 没有配置dataSource 参考技术B 错误很明显啊，说的也很清楚Error creating bean with name 'personDao' defined in class path resource [applicationContext.xml]: Cannot resolve reference to bean 'dataSource' while setting bean property 'dataSource';本回答被提问者和网友采纳 参考技术C 注入的问题

Spring配置文件出错

问题描述：

Element ‘xxxxxxx‘ cannot have character [children],because the type‘s content type is element-only

解决方案：

配置文件中的beans节点下面只能是元素节点，不能有字符或文本存在。

比如多余的标点符号，点，也有可能是空格。

所以将9到12行注释成这样就行了；

<!--
//1.property表示给成员变量（属性）赋值
//2.调用set方法
//3.name表示属性名
//4.ref表示bean的id名
-->
