【求助 】使用 schemaless 写入超级表 运行SchemalessWsTest.java报错

[jiachengjiang]

具体报错信息如下： [WebSocketConnectReadThread-12] DEBUG com.taosdata.jdbc.ws.WSClient - disconnect uri: ws://127.0.0.1:6041/ws, code : 1002 , reason: Invalid status code received: 404 Status line: HTTP/1.1 404 Not Found, remote: false
Exception in thread "main" java.sql.SQLException: ERROR (0x231d): can't create connection with server within: 60000 milliseconds

本地docker 搭建的 tdengine 版本号3.1.1.0

taos-jdbcdriver版本 3.2.11

tdengine 版本3.1.1.0直接用REST 连接batchfetch 参数并设置为 true，开启 WebSocket 连接 不支持吧
