同学你好，根据同学的表述之前运行正常，建议同学清理一下idea的缓存，重新运行项目，试一下，具体如下：

http://img1.sycdn.imooc.com//climg/5e44bb8a09fc021602440193.jpg

并且同学和上次运行相比是否修改了什么配置呢？如果修改了，建议同学检查一下修改内容的正确性。

如果我的回答解决了你的疑惑，请采纳！祝学习愉快！

同学你好，SAXParseException异常表示xml文件解析出现问题，根据报错信息，建议同学检查一下spring-dao.xml文件的第7行左右。

具体如下：

http://img1.sycdn.imooc.com//climg/5e43cf0e09764b8908130170.jpg

建议检查一下xml的编写问题。同学也可以下载源码，对比着看下。查看是否重复配置了同一个bean配置文件。

如果我的回答解决了你的疑惑，请采纳！祝学习愉快！

    老师，我就是完全copy源码的配置文件，之前运行正常，但是今天就出现了这个“文档根元素 "beans" 必须匹配 DOCTYPE 根 "null"。”的问题，到底该怎么解决？
