Invalid bound statement (not found): com.ruoyi.system.mapper.UserMapper.selectUserList

Springboot项目如果出现错误
Invalid bound statement (not found): com.ruoyi.system.mapper.UserMapper.selectUserList

解决办法：在mapper工程下的pom文件中加入下面的内容，让mapper映射文件加载到target的classes中去

<!-- 如果不添加此节点mybatis的mapper.xml文件都会被漏掉。 -->

      <build>

            <resources>

                <filtering>false</filtering>
