- 错误2：
org.apache.ibatis.binding.BindingException: Invalid bound statement (not found)
# 参考：https://cloud.tencent.com/developer/article/1896205
# 错误原因：interface与xml不能对应
# 我这里的报错原因是因为ddd项目中xml映射文件放在domain路径下，将xml放到resource路径下可解决
# 错误还原2：cloud + ddd 项目中报错，xml映射文件放在com.chnq.provide.domain.repository.mapper.xml路径下
# 解决方案：在子模块的pom中配置如下，自动扫描xml
<resources>
<resource>
<directory>src/main/java</directory>
<includes>
<include>**/*.xml</include>
</includes>
</resource>
</resources>
- 错误3：
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'deptsController': Unsatisfied dependency expressed through field 'deptService';
项目详情：cloud项目的子模块使用mybatis，之后又集成了mybatis plus，
错误原因1：项目中有多个实体类文件夹，
错误原因2：包名实现类等是否正确
