ToOneRelation

public ToOneRelation(String selfField,
                     String targetSchema,
                     String targetTable,
                     String targetField,
                     String valueField,
                     String joinTable,
                     String joinSelfColumn,

方法详细资料

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

getTargetMappingValue

private String getTargetMappingValue(List<Row> mappingRows,
                                     Object selfValue)
