【原因】：我的原因是服务解析下面路径时出现了问题，我的配置如下：同事这也却没有问题，心里真不是滋味。
1 mybatis-plus:
2 mapper-locations: classpath*:/mapper/*Mapper.xml
【解决方案一】：直接定义为全路径
1 mybatis-plus:
2 mapper-locations: classpath:/src/main/resources/mapper/*Mapper.xml
【解决方案二】：Maven 项目，在 pom 文件的 resource 中指定 xml 路径
1 <build>
2 <resources>
3 <resource>
4 <!-- xml放在java目录下-->
5 <directory>src/main/java</directory>
6 <includes>
7 <include>**/*.xml</include>
8 </includes>
9 </resource>
10 <!--指定资源的位置（xml放在resources下，可以不用指定）-->
11 <resource>
12 <directory>src/main/resources</directory>
13 </resource>
14 </resources>
15 </build>
【解决方案三】：如果只是一个 mapper.xml 文件，直接指定也不会出现问题
1 mybatis-plus:
2 mapper-locations: /mapper/ZoneMapper.xml
【解决方案四】： 【目前使用的方案】因为加载 *Mapper.xml 文件的时候，里面配置了二级缓存【我生成的时候不小心生成的】，这个时候，就会出现上述的问题。而且二级缓存是有缺陷的，可能会导致获取到的数据是旧数据，也就是关联的数据没有更新的问题。所以我们项目是关闭的，那么当我注释掉二级缓存之后，这个问题也就解决了。
1 <!-- 开启二级缓存 -->
2 <!-- <cache type="org.mybatis.caches.ehcache.LoggingEhcache"/>-->
