batch insert into supertable according to documentation fails

我的需求是批量给超表插入子表以及数据。数据源是用ws链接。设置异步写入:

@Bean(name = "tdengineDataSource")
    public DataSource tdengineDataSource() {
        Properties props = new Properties();
        props.setProperty("user", jdbcUsername);
        props.setProperty("password", jdbcPassword);
        props.setProperty("charset", "UTF-8");
        props.setProperty("timeZone", "UTC-8");
        props.setProperty("enableAutoReconnect", "true");
        //异步写入
        props.setProperty("asyncWrite", "stmt");
        props.setProperty("batchSize", String.valueOf(BATCH_SIZE));
        props.setProperty("cacheSize", String.valueOf(CACHE_SIZE));
        props.setProperty("backendWriteThreads", String.valueOf(BACKEND_WRITE_THREADS));
        DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setUrl(jdbcUrl);
        dataSource.setDriverClassName("com.taosdata.jdbc.ws.WebSocketDriver");
        dataSource.setConnectionProperties(props);
        return dataSource;
    }

批量写入代码:

 public int addPointValue(List<PointDTO> list, String measurement) {
        // 插入数据到TDengine表的逻辑
        if(ObjectUtil.isEmpty(list)){
            log.error("PointDTO list is empty");
            return 0;
        }
        int totalRows = 0;
        int batchCount = 0;
        String sql = "INSERT INTO ? USING point_model TAGS (?) VALUES (?, ?)";
        //开始时间戳
        StopWatch stopWatch = new StopWatch();
        stopWatch.start();
        try (Connection conn = tdengineDataSource.getConnection();
             TSWSPreparedStatement ps = conn.prepareStatement(sql).unwrap(TSWSPreparedStatement .class))
        {
            for (PointDTO p : list) {
                //设置table
                ps.setTableName("point_model_"+p.getPointId());
                //设置tag
                ps.setTagString(0, p.getPointId());
                //设置columns
                ps.setTimestamp(1, new java.sql.Timestamp(p.getTime().getTime()));
                ps.setLong(2, p.getValue().longValue());
                ps.addBatch();
                totalRows++;
                batchCount++;
                if (totalRows % 1000 == 0) {
                    ps.executeBatch();
                    // 设置异步，确保数据落盘
                    ps.executeUpdate();
                    batchCount=0;
                }
            }
            if (batchCount > 0) {
                ps.executeBatch();
                // 设置异步，确保数据落盘
                ps.executeUpdate();
            }
            stopWatch.stop();
            log.info("Insert {} rows to TDengine, time elapsed: {} s.", totalRows, stopWatch.getTotalTimeMillis()/1000);
        }
        return totalRows; // 返回批量插入的条数
    }

         TSWSPreparedStatement ps = conn.prepareStatement(sql).unwrap(TSWSPreparedStatement .class))这个就报错了。java.sql.SQLException: Unable to unwrap to class com.taosdata.jdbc.ws.TSWSPreparedStatement。

要改成WSEWPreparedStatement，端点看到是：WSEWPreparedStatement。我改成WSEWPreparedStatement又不支持参数绑定了。
