QueryforList 结果显示 table 名称

Question

我使用springjdbctemplate从hive数据库查询数据

这是我的代码：

@RestController
public class QueryController {
    @Autowired
    protected JdbcTemplate hiveTemplate;

    @RequestMapping("/query")
    public List query() {
        List data = hiveTemplate.queryForList("select * from ecg.hivetbluserdata limit 100");
        return data;
    }
}

但是 returns 这个:

[{"hivetbluserdata.id_data":1,"hivetbluserdata.id_user":1,"hivetbluserdata.time":"Thursday, April 09, 2015 18:09:26","hivetbluserdata.ecgvalue":3.3871,"hivetbluserdata.inputtime":"2015-04-09 18:11:25.0"},
{"hivetbluserdata.id_data":2,"hivetbluserdata.id_user":1,"hivetbluserdata.time":"Thursday, April 09, 2015 18:09:26","hivetbluserdata.ecgvalue":1.56892,"hivetbluserdata.inputtime":"2015-04-09 18:11:25.0"},
{"hivetbluserdata.id_data":3,"hivetbluserdata.id_user":1,"hivetbluserdata.time":"Thursday, April 09, 2015 18:09:26","hivetbluserdata.ecgvalue":1.60802,"hivetbluserdata.inputtime":"2015-04-09 18:11:26.0"},
{"hivetbluserdata.id_data":4,"hivetbluserdata.id_user":1,"hivetbluserdata.time":"Thursday, April 09, 2015 18:09:26","hivetbluserdata.ecgvalue":2.09677,"hivetbluserdata.inputtime":"2015-04-09 18:11:26.0"},
{"hivetbluserdata.id_data":5,"hivetbluserdata.id_user":1,"hivetbluserdata.time":"Thursday, April 09, 2015 18:09:26","hivetbluserdata.ecgvalue":1.99902,"hivetbluserdata.inputtime":"2015-04-09 18:11:26.0"},
{"hivetbluserdata.id_data":6,"hivetbluserdata.id_user":1,"hivetbluserdata.time":"Thursday, April 09, 2015 18:09:26","hivetbluserdata.ecgvalue":1.97947,"hivetbluserdata.inputtime":"2015-04-09 18:11:26.0"},
{"hivetbluserdata.id_data":7,"hivetbluserdata.id_user":1,"hivetbluserdata.time":"Thursday, April 09, 2015 18:09:26","hivetbluserdata.ecgvalue":1.94037,"hivetbluserdata.inputtime":"2015-04-09 18:11:26.0"},
{"hivetbluserdata.id_data":8,"hivetbluserdata.id_user":1,"hivetbluserdata.time":"Thursday, April 09, 2015 18:09:27","hivetbluserdata.ecgvalue":1.56892,"hivetbluserdata.inputtime":"2015-04-09 18:11:26.0"},

我不想显示 table 姓名（hivetbluserdata 是 table 姓名）。我该如何解决这个问题？

Answer 1

您可以使用以下 Hive 配置属性来禁用结果集中的 table 个名称：

<property>
   <name>hive.resultset.use.unique.column.names</name>
   <value>false</value>
</property>

参考：

https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-hive.resultset.use.unique.column.names

hive.resultset.use.unique.column.names

Default Value: true

Added In: Hive 0.13.0 with HIVE-6687

Make column names unique in the result set by qualifying column names with table alias if needed. Table alias will be added to column names for queries of type "select *" or if query explicitly uses table alias "select r1.x..".
