Springboot + MySQL + Driver Class Not Found

Question

I'm doing a simple spring boot project with a thread pool and MySQL in order to connect to MySQL whenever I'm adding spring-boot-starter-jdbc I'm getting below error.

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in class path resource [org/springframework/boot/autoconfigure/jdbc/DataSourceConfiguration$Tomcat.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.apache.tomcat.jdbc.pool.DataSource]: Factory method 'dataSource' threw exception; nested exception is java.lang.IllegalStateException: Cannot load driver class: com.mysql.jdbc.Driver

Answer 1

It seems like you are missing mysql-connector dependency, Add these to your pom.

Maven:

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

or gradle:

compile "mysql:mysql-connector-java:*"
