初一看到这个问题会以为是mapper.xml文件没有获取到。有过使用maven构建ssm项目经验的朋友应该有体会，遇到这种就直接加一段pom配置就好了（资源拷贝）。

springboot中是不是也是这样呢？

看一看编译之后的目录就知道了~~



发现问题并不是这样。

好吧那就debug 进来跟一下看看什么情况~~

在这里得到了答案：[花非花-雾非雾] 的博客(http://blog.csdn.net/li396864285/article/details/75035967)





这时候就发现 service 上竟然被注入了proxy “org.apache.ibatis.binding.MapperProxy@57406531” 这样的mybatis相关的类。

罪魁祸首竟然是因为配置的mapper扫描的路径包括了太多的bean 会给service的dean也注入mybatis相关的代理类



改成这样就OK了（仅扫描mapper对应的包）：
