springboot 项目使用 Mapper 时遇到IDEA: org.apache.ibatis.binding.BindingException: Invalid bound statement (not found)异常。
很多次了，老是会忘记，记录一下

原因是找不到我们写的mapper.xml，需增加以下两个地方配置信息：

application.properties

#mbatis 映射
mybatis.type-aliases-package=com.fengmi.mac_keeper
mybatis.mapper-locations=classpath*:com/fengmi/mac_keeper/**/*.xml

pom.xml

编译时增加 resource 过滤xml，这样我们定义的 *Mapper.xml 就能在编译的时候编进去了。
