Java, like Android or Python, is a widely-used programming language nowadays. Websites built with Java always have numerous advantages and are appropriate for large companies.

When you try to use mysql and spring boot, you get the warning “Reason: Failed to load driver class com.mysql.jdbc.Driver“.

This software error is so prevalent that this could happen to anyone. Consequently, how did it come to be, or is it fixable? Let’s discuss it together.

The cause of the error ”Reason: Failed to load driver class com.mysql.jdbc.Driver”

This error happens because of many reasons. You are trying to utilize mysql and spring boot, but you face the following problem. “Reason: Failed to load driver class com.mysql.jdbc.Driver; in either of HikariConfig class loader or Thread context classloader”

In another case, you are attempting to run the Spring Boot codebase with two figures, one for the H2 in-memory computing and the other with MySQL. The H2 database is fine, but then you switch to MySQL and get this error.

You also encounter this error in the case MySql Database Driver Class Name, MySql Database Driver jar Version, and MySql Database Version mismatches. This mismatch prevents the Java program from loading the configured driver class, so the error happens.

“Property: driverclassname 
Value: com.mysql.jdbc.Driver; 
Origin: "driverClassName" from property source "source" 
Reason: Failed to load driver class com.mysql.jdbc.Driver; in either of HikariConfig 
class loader or Thread context classloader”.

To fix “Reason: Failed to load driver class com.mysql.jdbc.Driver” error

Surprisingly, you could easily solve it by completing the instructions outlined below.

Method 1: Downgrade The Mysql-connector-java To Its Version 5.1.38

Downgrading the Mysql-connector-java to its version 5.1.38 is the best way to solve the “Reason: Failed to load driver class com.mysql.jdbc.Driver” error. Look at this example:

<dependency> 
        <groupId>mysql</groupId> 
        <artifactId>mysql-connector-java</artifactId> 
        <version>5.1.38</version> 
    </dependency>

Method 2: Add The Dependency

For our second method, you must add the dependency by using this script. And then your problem would be resolved.

<dependency> 
     <groupId>mysql</groupId> 
     <artifactId>mysql-connector-java</artifactId> 
</dependency>

Method 3: Use the updated database driver jar

Let’s use the updated database driver jar to connect to a MySQL database from Java to handle “Reason: Failed to load driver class com.mysql.jdbc.Driver” issue if you are running Java version 1.8 or above and MySQL version 5.6 or higher. The class name for the driver is com.mysql.cj.jdbc.Driver. The database login information is listed below.

spring.datasource.url=jdbc:mysql:driver://localhost:3306/test
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL5Dialect

Method 4: Use the older mysql database driver jar

The older database driver class is neccessary to connect to a MySQL database from Java if your legacy application employs Java version 1.7 or lower or MySQL version 5.5 or lower. It is best to use the older Mysql database driver jar. 5.1.48 is the most recent version of the old mysql database driver.

<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.48</version>
</dependency>

Above methods are the most effective ones to fix “Reason: Failed to load driver class com.mysql.jdbc.Driver” error. Let’s do as these suggestions to get the desired result.

Conclusion

“Java” is commonly referred to as the Java platform, a set of tools that allows for easy cross-platform application development. The Java programming language is one general-purpose programming language commonly used to develop programs for this platform. If the you get problem “Reason: Failed to load driver class com.mysql.jdbc.Driver” persists, let’s try the above remedies. If you need assistance or have other Java questions, many researchers are always keen to help. Finally, we hope all of our readers have a splendid day filled with new ideas.
