Invalid bound statement (not found)

同学你好，建议同学修改后的项目结构截图贴一下。另外建议同学检查一下target目录下dao和xml文件是否在一起，如：

祝： 学习愉快~

前面曾经遇到过数据库连接的问题，用了图片中的方法改了密码，不知道是不是有影响，回答问题可以参考

同学你好，建议同学在数据库的url链接后加上useSSL=false再试试呢？如：

jdbc:mysql://localhost/3306/oa?useUnicode=true&characterEncoding=utf-8&useSSL=false

如果我的回答解决了你的疑惑，请采纳。祝：学习愉快~

这是更加详细的报错信息，之前spring-mvc.xml在的包被我改正为com.imooc.oa.dao,改正之前是com.imooc.dao，创建过程也是用（/）分割。错误依旧存在

这是我的IDE报错信息

同学你好，问一下同学在建resources目录下的包时，使用的点( . )分隔的还是斜杠分隔的( / )的。如果是用点分割的，建议同学重新建一下resources目录的com.sm.dao，使用斜杠分隔再试试。如果还有问题，建议同学将详细的报错信息贴一下。

如果我的回答解决了你的疑惑，请采纳。祝：学习愉快~
