Hibernate don't persist in database - spring

Question

I'm new in using spring mvc and this is my first application , so I Followed a tutorial and I have a problem . When I run the server(Tomcat ) , hibernate don't persist or add table in mydatabase , when I drop the schema It cause a warning :
WARN: HHH000342: Could not obtain connection to query metadata : Cannot create PoolableConnectionFactory (Unknown database 'tests')
So I understand that there is no problem with the connection with the database .
this is the pom.xml :
