文件结构是这个样子,mapper.xml文件在resources/mappers/fdms目录下面

通常来说, 将mapper打包到target目录下只需要在maven下面配置

 

 <resources><resource><directory>src/main/resources</directory><filtering>true</filtering><includes><include>com.dtcloud.soe/*</include><include>**/*.xlsx</include><include>*.xml</include><include>*.yml</include><include>*.json</include><include>*.properties</include><include>*.conf</include><include>mappers/fdms/*.xml</include></includes></resource><resource><directory>src/main/resources/${profiles.active}</directory><filtering>false</filtering></resource></resources>

就行了,但是我配置好了还是不行,经过仔细检查之后发现 , 原来我的目录结构错了, 我的是这样子的

但是在idea中完全看不出来,

这个问题有时候非常难以发现, 必须要打开文件结构才能发现, 是一个很隐秘的坑
