Java – Spring boot Bean exception: Cannot determine embedded database driver class for database type NONE

I am trying to run a spring boot application which is made by someone else. I have tried to attach my local database to the application but when I run this, it gives the following error;

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private javax.sql.DataSource org.springframework.boot.autoconfigure.orm.jpa.JpaBaseConfiguration.dataSource; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in class path resource [org/springframework/boot/autoconfigure/jdbc/DataSourceAutoConfiguration$NonEmbeddedConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [javax.sql.DataSource]: Factory method 'dataSource' threw exception; nested exception is org.springframework.boot.autoconfigure.jdbc.DataSourceProperties$DataSourceBeanCreationException: Cannot determine embedded database driver class for database type NONE. If you want an embedded database please put a supported one on the classpath. If you have database settings to be loaded from a particular profile you may need to active it (no profiles are currently active).

I am new to this and I can't find out what is the problem. Some details:

where xxx = name of the database.

Workbench:

Name: Local instance wampmysqld64
Host: localhost
Port: 3306
Server: MySQL Community Server (GPL)
Version: 5.7.18-log
Connector: C++ 1.1.4 
Login User: root
Current User: root@localhost
SSL: Disabled

And the server is up and running.

I run the Spring boot application with CMD using the command: java -jar xxx.jar
