按照 [MySQL 文档](https://dev.mysql.com/doc/connector-j/en/)中的说明下载并配置 Java JDBC 驱动程序即可使用。对于 TiDB v6.3.0 及以上版本，建议使用 MySQL Connector/J 8.0.33 及以上版本。

> 在 8.0.32 之前的 MySQL Connector/J 8.0 版本中存在一个 [bug](https://bugs.mysql.com/bug.php?id=106252)，当与 TiDB v6.3.0 之前的版本一起使用时，可能会导致线程卡死。为了避免此问题，建议使用 MySQL Connector/J 8.0.32 或更高版本，或者使用 TiDB JDBC（见 *TiDB-JDBC* 标签）。

MySQL Connector/J 8.0 与 TiDB v7.5.0版本一起使用 时，建议将 TiDB 配置项 [`server-version`](https://docs.pingcap.com/tidb/v7.5/tidb-configuration-file#server-version) 设置为`"5.7.25-TiDB-v7.5.0"`。如果 TiDB 服务器报告的是 MySQL 8.0.11 或以上版本，MySQL Connector/J 会尝试访问 `information_schema.KEYWORDS` 表。但是，该表不会出现在TiDB v7.5.0 中。
