java mysql SSL 連接

Question

我正在嘗試建立從 java 應用程序到 mysql 服務器的 SSL 連接。 以下是設置細節。

• java 8
• mysql 服務器版本：5.7.28
• mysql-connector-java-8.0.12
• 連接字符串：jdbc:mysql://localhost:3306/carbon_mysql?autoReconnect=true&useSSL=true&requireSSL=true

但是當我嘗試通過 java 應用程序連接時，會引發以下異常。

Caused by: com.mysql.cj.exceptions.WrongArgumentException: Malformed database URL, failed to parse the connection string near '=true&requireSSL=true'.

嘗試將您的連接 url 更改為

jdbc:mysql://localhost:3306/carbon_mysql?autoReconnect=true&useSSL=true&requireSSL=true&verifyServerCertificate=true

您還必須確保您已在 mysql 上授予 ssl。 在 MySQL 服務器中以 root 身份登錄，並運行下面給出的查詢：

GRANT USAGE ON *.* TO 'root'@'%' REQUIRE SSL; 
FLUSH PRIVILEGES;
