这是一个MySQL JDBC驱动程序的警告信息,告诉你正在使用的驱动程序已经过时,建议使用新的驱动程序。如果你想消除这个警告信息,可以将代码中的旧驱动程序类名替换为新的驱动程序类名。例如,将`com.mysql.jdbc.Driver`替换为`com.mysql.cj.jdbc.Driver`。如果你不想消除这个警告信息,也可以忽略它,因为它并不会影响代码的正常运行。

com.mysql.jdbc.Driver'. This is deprecated. The new driver class is
The class 'com.mysql.jdbc.Driver' is a JDBC driver class for connecting to MySQL databases. However, it has been deprecated and is no longer recommended for use. The new driver class for MySQL is 'com.mysql.cj.jdbc.Driver'. This new driver class is part of the Connector/J library, which is the official JDBC driver for MySQL.
The 'com.mysql.cj.jdbc.Driver' class provides improved performance, security, and compatibility with the latest versions of MySQL. It supports features such as SSL/TLS encryption, connection pooling, and handling of time zone conversions.
If you are using an older version of the MySQL JDBC driver in your application, it is recommended to update to the latest version and use the 'com.mysql.cj.jdbc.Driver' class instead. This will ensure that your application can take advantage of the latest features and improvements provided by the new driver.
Loading class `com.mysql.jdbc.Driver'. This is deprecated.
这是因为使用了过时的 MySQL 驱动程序。建议使用最新版本的 MySQL 驱动程序。以下是使用最新版本的 MySQL 驱动程序的示例代码:
```
Class.forName("com.mysql.cj.jdbc.Driver");
Connection conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/mydatabase?useUnicode=true&characterEncoding=utf-8&serverTimezone=UTC", "username", "password");
```
请注意,这里使用的是 `com.mysql.cj.jdbc.Driver`,而不是 `com.mysql.jdbc.Driver`。
