本文介绍如何将旧版MySQL驱动com.mysql.jdbc.Driver更新为新版com.mysql.cj.jdbc.Driver，以避免因使用已弃用的驱动而导致的问题。通过简单的步骤指导，帮助开发者顺利完成驱动升级。

报错：

com.mysql.jdbc.Driver'. This is deprecated. The new driver class is

`com.mysql.cj.jdbc.Driver'. The driver is automatically registered via the SPI and manual loading of

the driver class is generally unnecessary.

改成这样：

04-18

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.
