问题分析
dao层编译后只有class文件，没有mapper.xml，因为maven工程在默认情况下src/main/java目录下的所有资源文件是不发布到target目录下的，
解决方案
在pom中配置如下节点
<build>
<resources>
<resource>
<directory>src/main/java
</directory>
<includes>
<include>**/*.xml
</include>
</includes>
<filtering>false
</filtering>
</resource>
</resources>
</build>
在Spring Boot配置文件中添加配置
#配置mapper xml文件的路径
mybatis-plus.mapper-locations=classpath:com/guli/edu/mapper/xml/*.xml
重新打包项目会发现target目录下出现了xml文件夹
