同学你好，报错提示绑定错误，找不到selectAll方法，如：

http://img1.sycdn.imooc.com//climg/5e54d8d609487c6e07820093.jpg

问一下resources目录下的包名是否和dao层的包名一样，如：

http://img1.sycdn.imooc.com//climg/5e54d93f098a2f8803670426.jpg

如果包名一样，同学resources目录下的包名创建时是否使用的斜杠/分隔。如果不是使用的斜杠分隔，建议同学使用斜杠分隔再试试。

如果我的回答解决了你的疑惑，请采纳。祝：学习愉快~

    感谢老师，只是有个疑问，为什么用斜杠分隔就可以解决这个问题呢？

  • 好帮手慕阿满 回复 韩熙Excellent #2
    同学你好，使用斜杠分隔有分层的效果，正好和dao包中的DepartmentDao文件对应，发布项目时，会将DepartmentDao文件以及对应的xml文件发布到同一个目录下，这样就不会报错了。祝：学习愉快~
