Hibernate does not create tables automatically [closed]

Question

I have Maven project with Hibernate and Spring framework. I want Hibernate to create tables automatically, but all existing tables are just dropped and the required tables are not created. No exceptions are thrown during session factory initialization, but when I try save a Player entity, exception is thrown:

com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Table 'billboarddb.player' doesn't exist

If I create the tables manually and change the property hibernate.hbm2ddl.auto to "validate", then everything works fine. Do you have any idea, why Hibernate does not create the tables?

Spring configuration file:

<context:component-scan  base-package="org.meluk.billboard.business.controller" />
<tx:annotation-driven transaction-manager="txManager" />
<bean id="propertyConfigurer"  class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <property name="locations" >
        <list>
            <value>/WEB-INF/config/jdbc.properties</value>
        </list>
    </property>
</bean>
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
    <property name="driverClassName" value="${hibernate.connection.driver_class}" />
    <property name="url" value="${hibernate.connection.url}" />

</bean>

            <prop key="hibernate.c3p0.max_statements">${hibernate.c3p0.max_statements}</prop>
        </props>
    </property>
</bean>

<bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory" />
</bean>

jdbc.properties file:

hibernate.connection.driver_class=com.mysql.jdbc.Driver

Answer 1

I solve the problem. Hibernate could not create tables with MysqlInnoDBDialect. Now I use MySQL5InnoDBDialect instead.

Answer 2

Add the following entry to the hibernateProperties props.

<prop key="hibernate.hbm2ddl.auto">create</prop>
