application.properties

spring.jpa.hibernate.ddl-auto=create-drop
spring.jpa.generate-ddl=true
spring.jpa.show-sql=true
spring.datasource.url=jdbc:mysql://database-2.**..amazonaws:3306/mydb
spring.datasource.username=admin
spring.datasource.password=*****
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver

How to resolve this issue? I get below exception:

Error creating bean with name 'dataSource' defined in class path resource [/springframework/boot/autoconfigure/jdbc/DataSourceConfiguration$Hikari.class]: Failed to instantiate [com.zaxxer.hikari.HikariDataSource]: Factory method 'dataSource' threw exception with message: Failed to determine a suitable driver class
