错误提示
com.mysql.jdbc.exceptions.MySQLNonTransientConnectionException: Client does not support authentication protocol requested by server; consider upgrading MySQL client
错误原因
Mysql8 之前的版本中加密规则是mysql_native_password,而在Mysql8之后,加密规则是caching_sha2_password
笔者在jsp中使用的Mysql的架包是mysql-connector-java-5.0.8-bin.jar，如果使用的MySql8以上就会报错
解决办法
更换加密算法
mysql> select version(); +-----------+ | version() | +-----------+ | 8.0.17 | +-----------+ 1 row in set (0.01 sec) mysql> ALTER USER ‘root‘@‘localhost‘ IDENTIFIED WITH mysql_native_password BY ‘123‘; Query OK, 0 rows affected (0.02 sec) mysql> FLUSH PRIVILEGES; Query OK, 0 rows affected (0.01 sec)
