Class BaseService<M extends com.baomidou.mybatisplus.core.mapper.BaseMapper<T>, T>

java.lang.Object
com.baomidou.mybatisplus.extension.repository.AbstractRepository<M,T>
com.baomidou.mybatisplus.extension.repository.CrudRepository<M,T>
com.baomidou.mybatisplus.extension.service.impl.ServiceImpl<M,T>
com.codeupsoft.base.service.BaseService<M,T>
Type Parameters:
M - Mapper接口类型
T - 实体类型
All Implemented Interfaces:
com.baomidou.mybatisplus.extension.repository.IRepository<T>, com.baomidou.mybatisplus.extension.service.IService<T>
public class BaseService<M extends com.baomidou.mybatisplus.core.mapper.BaseMapper<T>, T> extends com.baomidou.mybatisplus.extension.service.impl.ServiceImpl<M,T>
业务服务基类.

所有业务Service都应该继承此类，提供统一的CRUD操作和通用业务方法. 基于MyBatis-Plus的ServiceImpl，自动拥有常用的数据库操作方法.
