删除persistence.xml hibernate中标记的使用

Question

我有一个关于Spring 3.1.1 Hibernate 4.1.1 jsf 2.1.6的演示项目

<persistence-unit name="app-persistance"
    transaction-type="RESOURCE_LOCAL">
    <provider>org.hibernate.ejb.HibernatePersistence</provider>

    <!-- ********* HAS Entries ********* -->
            <class>com.myapp.domain.classA</class>
            <class>com.myapp.domain.classB</class>
            <!-- ******More Domain classes here ***-->

和我的ApplicationContext.xml片段如下：

    <property name="persistenceUnitName" value="app-persistance" />
    <property name="dataSource" ref="dataSource" />
    <property name="jpaProperties">
        <props>
            <prop key="hibernate.dialect">${hibernate.dialect}</prop>
            <prop key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl.auto}</prop>
            <prop key="hibernate.show_sql">${hibernate.show_sql}</prop>
            <prop key="javax.persistence.validation.mode">none</prop>
            <prop key="javax.persistence.sharedCache.mode">all</prop>
            <prop key="hibernate.search.default.directory_provider">org.hibernate.search.store.impl.FSDirectoryProvider
            </prop>
            <prop key="hibernate.search.default.indexBase">c:/lucene/indexes</prop>
        </props>
    </property>

</bean>

<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager"
    scope="singleton">
    <property name="entityManagerFactory" ref="entityManagerFactory" />
</bean>

应该做些什么，以使创建的任何新域类、persistence.xml标记项都不是必需的，并且SQL表可以在DB中自动创建

因为我已经在applicationcontext.xml中添加了以下内容

${hibernate.hbm2ddl.auto}

Answer 1

在EntityManagerFactorybean声明中包括以下属性

<property name="packagesToScan" value="com.myapp.domain"/>

并从persistence.xml中删除所有类声明
