Question

我正在使用NamedParameterJdbcTemplate，我想使用on conflict sql语句进行批量更新

sql = "INSERT INTO bl_crm_activity_line (guid,hdr_guid) VALUES (:guid, :hdr_guid,)
        ON CONFLICT (guid) DO UPDATE  SET guid = :guid, hdr_guid = :hdr_guid"

该查询适用于1次插入或更新：

Map<String, Object> m = objectMapper.convertValue(object, Map.class);
jdbcTemplate.update(query, m);

但是当我用该对象的列表进行批量更新时（我试过两种方式）：

选项1

Map<String, Object>[] mapsToStore = objsToStore.stream().map(x -> convertObjectToMap(x)).toArray(HashMap[]::new); 
this.jdbcTemplate.batchUpdate(query, mapsToStore);


public Map<String, Object> convertObjectToMap(Object objToStore) {
      Map<String, Object> m = objectMapper.convertValue(objToStore, Map.class);
      return m;
  }

选项2

  SqlParameterSource[] batch =
 SqlParameterSourceUtils.createBatch(objectList.toArray());
         jdbcTemplate.batchUpdate(query, batch);

选项1和2都会抛出此错误

不确定我做错了什么。请协助

插入冲突（guid）使用NamedParameterJdbcTemplate进行批量更新不起作用
