报错信息：

 Invalid bound statement (not found): com.atguigu.auth.mapper.SysMenuMapper.findMenuListByUserId 

因为：maven加载机制

maven默认情况下，只会加载编译ser-main-java目录里面java类型文件，其他类型文件不会进行加载

解决方法：

1、吧xml文件放到resources目录下面

2、通过配置方式进行加载

1、在pom.xml

<!--        maven记载机制1、在pom.xml添加-->
<resources><resource><directory>src/main/java</directory><includes><include>**/*.yml</include><include>**/*.properties</include><include>**/*.xml</include></includes><filtering>false</filtering></resource><resource><directory>src/main/resources</directory><includes><include>**/*.yml</include><include>**/*.properties</include><include>**/*.xml</include></includes><filtering>false</filtering></resource>
</resources>

2、项目配置文件添加

mybatis-plus:mapper-locations: classpath:com/atguigu/auth/mapper/xml/*.xml # 加载xml文件
