MACOS mysql 5.7 Navicat 可以连接 ， Java 报错

[sq1036]

com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException: Could not create connection to database server. Attempted reconnect 3 times. Giving up.

Caused by: java.sql.SQLException: Access denied for user 'root'@'localhost' (using password: YES)

找了半天了 试过以下方法： GRANT ALL PRIVILEGES ON . TO root @'%' IDENTIFIED BY "123456"; FLUSH PRIVILEGES; GRANT ALL PRIVILEGES ON . TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION; flush privileges; alter user 'root'@'localhost' identified with mysql_native_password by '123456';

ALTER USER 'root'@'localhost' IDENTIFIED BY '123456' PASSWORD EXPIRE NEVER;

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '123456';

都不行还是这样，有遇到过类似的问题的老哥吗 我去抽根烟，收拾下掉地上的头发，一会儿回来继续

换一个版本的驱动包试试

@Jooooooooo 感谢分享思路，更换了两个版本，还是不行

问题定位到了，HikariPool 这个连接池，跟数据库没关系，原生 jdbc 可以连接，但池初始化报错 Access denied
