我是 h2 数据库的新手。我创建了如下所示的 sessionfactory。

<bean id="dataSource"
        class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="org.h2.Driver" />
        <property name="url" value="jdbc:h2:~/selva;DB_CLOSE_DELAY=-1" />
        <property name="username" value="" />
        <property name="password" value="" />
    </bean>

    <bean id="sessionFactory"
        class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />

        <property name="annotatedClasses">
        <list>
            <value>com.selva.meetinghall.domain.My</value>  
            </list>
        </property>
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">${hibernate.dialect}</prop>
                <prop key="hibernate.show_sql">${hibernate.show_sql}</prop>




            </props>
        </property>
    </bean>

我的.java

@Entity
@Table(name="my")
@Repository
public class My implements java.io.Serializable {
    private static final long serialVersionUID = -1798070786993154670L;
     @Id
     @Column(name ="Id")
     private int id;
     @Column(name ="Name")
     private String name;
    //getter and setter
}

道：

Session session=sessionfactory.openSession();
    Transaction tx=session.beginTransaction();
    My my=new My();
    my.setId(1);
    my.setName("selva");
    session.save(my);
    tx.commit();

我得到了如下错误。

Hibernate: insert into my (Name, Id) values (?, ?)
2015-01-20 18:41:02,911 WARN  org.hibernate.util.JDBCExceptionReporter.logExceptions:77 - SQL Error: 42102, SQLState: 42S02
2015-01-20 18:41:02,911 ERROR org.hibernate.util.JDBCExceptionReporter.logExceptions:78 - Table "MY" not found; SQL statement:

org.hibernate.exception.SQLGrammarException: could not insert: [com.selva.meetinghall.domain.My]

上面的代码适用于 mssql 持久数据库。但不适用于 h2 数据库。我的方法有什么问题？内存和持久数据库的查询是否不同？任何帮助将不胜感激！！
