java - Does Hibernate create tables in the database automatically

Question

Upon reading this (archived) tutorial, they have not mentioned anything over creating tables in the DB. Does the Hibernate handle it automatically by creating tables and fields once i specify them.

Here is my beans configuration.

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:p="http://www.springframework.org/schema/p"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">

    <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/WEB-INF/jsp/" p:suffix=".jsp" />
    
    <bean id="myDataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
        <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
        <property name="url" value="jdbc:mysql://127.0.0.1:3306/spring"/>
        <property name="username" value="monwwty"/>
        <property name="password" value="www"/>
    </bean>
    
    <bean id="mySessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
        <property name="dataSource" ref="myDataSource" />
        <property name="annotatedClasses">
            <list>
                <value>uk.co.vinoth.spring.domain.User</value>
            </list>
        </property>
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
                <prop key="hibernate.show_sql">true</prop>
                <prop key="hibernate.hbm2ddl.auto">create</prop>
            </props>
        </property>
    </bean>
    
    <bean id="myUserDAO" class="uk.co.vinoth.spring.dao.UserDAOImpl">
        <property name="sessionFactory" ref="mySessionFactory"/>
    </bean>
    
    <bean name="/user/*.htm" class="uk.co.vinoth.spring.web.UserController" >
        <property name="userDAO" ref="myUserDAO" />
    </bean>
    
</beans>

Answer 1

your hibernate.hbm2ddl.auto setting should be defining that the database is created (options are validate, create, update or create-drop)
