接口 MPJRelationService<T>

所有超级接口:

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

从以下版本开始:

1.4.4
