Java应用使用人大金仓数据库启动时报错：
Caused by: com.kingbase8.util.KSQLException: The authentication type 10 is not supported. Check that you have configured the sys_hba.conf file to include the client's IP
address or subnet, and that it is using an authentication scheme supported by the driver.

报错提示不支持的认证类型。原因是使用了旧版的JDBC驱动包去连接新版本数据库，旧版驱动中缺少了某种认证类型。
解决方案：升级JDBC驱动
比如我这里是把kingbase-driver-8.2.0.jar替换为kingbase8-8.6.0.jar
