In your stack trace, in the end it shows the reason : 

Caused by: java.lang.ClassNotFoundException: com.mysql.jdbc.Driver

You need to add mysql-connector-java to your classpath.

Just add the following to your pom.xml (along with tag) 

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>6.0.6</version>
</dependency>

and in your application.properties add the following 

spring.jpa.database-platform=org.hibernate.dialect.MySQL5Dialect
spring.datasource.url=jdbc:mysql://localhost:3306/db_here
spring.datasource.username=mysqluser
spring.datasource.password=mysqlpwd 
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

Change the db url, username and pwd according to your mysql setup.
