GBase 8a数据库JDBC连接报错 Got packets out of order

GBase 8a 数据库集群,新版支持了sha256的用户密码加密,所以必须用对应的版本驱动。如果用来版本的,连接使用了sha256加密的用户,则会报Got packets out of order 错误。

报错样例

解决方案

更换新的支持sha256的jdbc驱动版本

[root@localhost gbase]# /usr/java/jdk1.8.0_271-amd64/bin/java -cp .:./gbase-connector-java-8.3.81.53-build55.5.7-bin_min_mix.jar Test
[root@localhost gbase]#

参考
