Failed to load driver class com.mysql.cj.jdbc.Driver from HikariConfig class classloader sun.misc.Launcher$AppClassLoader@18b4aac2
This error message is indicating that the HikariConfig class is unable to load the com.mysql.cj.jdbc.Driver class, which is required to establish a connection to a MySQL database.
There are a few potential reasons why this error might occur:
1. Missing MySQL driver: It's possible that the MySQL driver JAR file is not included in the classpath of the application. Make sure that the JAR file containing the com.mysql.cj.jdbc.Driver class is present in the classpath.
2. Incorrect driver class name: Double-check that the fully qualified class name for the MySQL driver is com.mysql.cj.jdbc.Driver. If you're using a different version of the driver, the class name may be slightly different.
3. Classloader issues: It's possible that there is a classloading conflict between the HikariConfig classloader and the classloader that loaded the MySQL driver. Try isolating the driver JAR file in a separate classloader or adjusting the classloading strategy.
To resolve this error, you can try the following steps:
1. Make sure the MySQL driver JAR file is included in the classpath of the application.
2. Double-check that the fully qualified class name for the MySQL driver is correct.
3. Try adjusting the classloading strategy or isolating the driver JAR file in a separate classloader.

这个错误通常是由于缺少 MySQL 驱动程序或驱动程序版本不兼容而导致的。请确保已经正确地安装并配置了 MySQL 驱动程序,并且使用的版本与您的应用程序兼容。您可以尝试使用最新版本的 MySQL 驱动程序并重新启动应用程序来解决这个问题。如果问题仍然存在,请检查您的 CLASSPATH 设置是否正确,以便在应用程序运行时能够找到 MySQL 驱动程序。
