手写spring-dao.xml遇到如下问题, 调了半天, 最后发现是是spring-dao.xml引用的my-batis.xml的问题.
总结经验如下:
1. 由于这个 Cause: org.xml.sax.SAXParseException; lineNumber: 7; columnNumber: 14;
并不一定是spring-dao.xml的行数, 事实上, 它正好是spring-dao.xml引用的my-batis.xml的错误行数.
2. 调Xml的bug是非常麻烦的. 可以考虑一段段删除可疑代码的方式来逐步定位到真正的问题代码所在行数.
3. 如果你百度不到一样的问题, 多半是你手误导致的独特问题.
