Why is 'Loading class com.mysql.jdbc.Driver ... is deprecated'?

"Loading class com.mysql.jdbc.Driver ... is deprecated"

Question:

What is the reason behind the warning message "Loading class com.mysql.jdbc.Driver. This is deprecated"?

Answer:

The warning message indicates that the com.mysql.jdbc.Driver class is no longer recommended. Instead, you should use the new driver class, com.mysql.cj.jdbc.Driver.

This change is due to the fact that JDBC 4.0 (released in Java 6) introduced a new way for drivers to be loaded. Prior to JDBC 4.0, it was necessary to manually load the driver class using Class.forName("com.mysql.jdbc.Driver"). However, JDBC 4.0 introduced the Service Provider Interface (SPI), which allows drivers to be loaded automatically if their JAR files are on the classpath.

While it is still possible to manually load the driver class, it is generally unnecessary and not recommended. Instead, you should simply add the driver JAR file to your classpath and let JDBC load the driver automatically.

Example:

If you are using Maven, you can add the following dependency to your pom.xml file:

<dependency>
    <groupid>mysql</groupid>
    <artifactid>mysql-connector-java</artifactid>
    <version>8.0.29</version>
</dependency>

This will add the JDBC driver JAR file to your classpath and allow JDBC to load the driver automatically.
