1.eclipse 連 mysql資料庫出現錯誤：nknown initial character set index ‘255‘ received from server. Initial client character set can be forced via the ‘characterEncoding‘ property.

解決方案：String url = "jdbc:mysql://localhost:3306/jdbcStudy?useUnicode=true&characterEncoding=utf8";

 

2.訪問報錯com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException: Client does not support authentication protocol requested by server; consider upgrading MySQL client

解決方案：

執行語句修改

 

mysql> ALTER USER ‘root‘@‘localhost‘ IDENTIFIED WITH mysql_native_password BY ‘66666‘;

 

Query OK, 0 rows affected (0.11 sec)
mysql> FLUSH PRIVILEGES;

 

Query OK, 0 rows affected (0.01 sec)

 

注意：root是使用者名稱，localhost是特指本機，mysql_native_password是舊的密碼驗證機制，66666是密碼
