Interface MPJRelationService<T>

All Superinterfaces:
com.baomidou.mybatisplus.extension.repository.IRepository<T>, com.baomidou.mybatisplus.extension.service.IService<T>
public interface MPJRelationService<T> extends com.baomidou.mybatisplus.extension.service.IService<T>
深度查询

对配置了映射注解的字段进行查询 目前查询深度只支持2级(只解析当前实体类的映射注解,不会对查询结果再次解析注解) 多级查询可能存在循环引用的问题，也可能会导致全量查询 用于替换deep
