org.hibernate.dialect.MySQLDialect true update jdbc:mysql://localhost:3306/redberry com.mysql.jdbc.Driver

Answer 1

With this create it will create a new schema every time you restart your server so your old tables data will be deleted:

  <property name="hbm2ddl.auto">create</property>

And with this update you can update old tables:

  <property name="hbm2ddl.auto">update</property>
