Class UncheckQueryConditionCrudServiceImpl<M extends CrudMapper<T>,T>

java.lang.Object

app.myoss.cloud.mybatis.repository.service.impl.BaseCrudServiceImpl<M,T>

app.myoss.cloud.mybatis.repository.service.impl.UncheckQueryConditionCrudServiceImpl<M,T>

Type Parameters:

M - "实体类"的 Mapper Interface 接口

T - 实体类

All Implemented Interfaces:

CrudService<T>

public class UncheckQueryConditionCrudServiceImpl<M extends CrudMapper<T>,T>
extends BaseCrudServiceImpl<M,T>

实现数据库表增、删、改、查常用操作的基类，不会检查通用查询条件字段是否为空，只要查询条件对象不为 null 即可。切记对于数据库表数据较多的时候，请不要使用此基类，应该使用 BaseCrudServiceImpl，去重写 BaseCrudServiceImpl.checkCommonQueryConditionIsAllNull(SqlCommandType, Result, Object, Map) 方法，这才是比较安全的做法，不然很可能被人使用为直接查询全表的数据。
