Я считаю, что это спящий режим. диалект проверьте ниже один раз.

<hibernate-configuration> 
    <session-factory> 
    <property name="hibernate.dialect"> 
     org.hibernate.dialect.MySQLDialect 
    </property> 
    <property name="hibernate.connection.driver_class"> 
     com.mysql.jdbc.Driver 
    </property> 

    <!-- Assume test is the database name --> 
    <property name="hibernate.connection.url"> 
     jdbc:mysql://localhost/test 
    </property> 
    <property name="hibernate.connection.username"> 
     root 
    </property> 
    <property name="hibernate.connection.password"> 
     root123 
    </property> 

    <!-- List of XML mapping files --> 
    <mapping resource="org.m.mi.UserDetails"/> 

</session-factory> 
</hibernate-configuration>
