mybatisplus @Select传参列表

直接看示例:

列表处理:

dictids = dictids + "'" +defineInfo.getDictionaryId() + "',"; }

处理结果示例:

'80500460','15874218','75106467','13010881','74244402','40883530','26553563','34135343','28425507','54467705','27436447','77228748','1731054','41308488','81248106',

切除最后的逗号:

String ids = DictIds.substring(0, DictIds.length() - 1);

MAP示例

public interface DictionaryInfoMapper extends BaseMapper<DictionaryInfo> {
    //使用列表传参,需要转换处理
    @Select(value = "select id,key as value,value as name from xxxx_xxxx_info where dictionary_id IN (${DictIds})")
    List<xxx> listDictfidlesByDictId(@Param("DictIds") String DictIds);
}

结果运行ok!
