研究方向: Investigate the TSDBJNIConnector.java file in the JDBC driver source to understand the JNI connection logic. Check TDengine client configuration: ensure server host, port, and authentication are correct. Review any recent changes to the JDBC driver or server connection handling. Consider reproducing with a minimal Java program outside Spring to isolate the issue.
