方法详细资料

customizeQueryWrapper

public void customizeQueryWrapper(QueryWrapper queryWrapper)

从类复制的说明: AbstractRelation

方便子类最近自定义的条件

覆盖:

customizeQueryWrapper 在类中 AbstractRelation<SelfEntity>

参数:

queryWrapper - 查询条件

join

public void join(List<SelfEntity> selfEntities,
                 List<?> targetObjectList,
                 List<Row> mappingRows)

指定者:

join 在类中 AbstractRelation<SelfEntity>

参数:

selfEntities - 当前的实体类列表

targetObjectList - 查询到的结果

mappingRows - 中间表的映射数据，非中间表查询的场景下，mappingRows 永远为 null

setMapKeyField

public void setMapKeyField(String mapKeyField)

getMapWrapType

public static Class<? extends Map> getMapWrapType(Class<?> type)
