Caused by: org.hibernate.HibernateException: Access to DialectResolutionInfo cannot be null when 'hibernate.dialect' not set.

Question

I am getting exception even after setting hibernate.dialect property. I am using hibernate 5.0.11 with spring boot 1.4.2 and mysql version as 5.7

application.properties is like this

# Hibernate
hibernate.dialect=org.hibernate.dialect.MySQL5Dialect
hibernate.show_sql=true
hibernate.hbm2ddl.auto=validate

pom.xml

        <groupId>org.springframework.boot</groupId>
