如何在Hibernate org.springframework.orm.hibernate3.LocalSessionFactoryBean中配置班级Spring的application context班级映射？我想将session factory类映射从以下hibernate.cfg.xml移动到相应的Spring会话工厂bean，以便我可以消除hibernate.cfg.xml。

档案hibernate.cfg.xml：

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
    "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
    "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
    <session-factory>
        <!-- ... -->
        <mapping resource="Queries.hbm.xml" />
        <mapping class="com.company.app.common.model.Account" />
        <mapping class="com.company.app.common.model.AccountCategory" />
        <mapping class="com.company.app.common.model.AssetType" />
        <mapping class="com.company.app.common.model.Book" />
        <mapping class="com.company.app.model.AssetTypeCategory" />
        <!-- ... -->
    </session-factory>
</hibernate-configuration>

档案spring-application-context.xml：

<bean id="sessionFactory"
    class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
    <property name="configurationClass">
        <value>org.hibernate.cfg.AnnotationConfiguration</value>
    </property>
    <property name="configLocation">
        <value>classpath:hibernate.cfg.xml</value>
    </property>

    <!-- Instead of the above, I want to use the following. Where and
    how do I define the class mappings so that I may eliminate
    hibernate.cfg.xml? -->
    <--
    <property name="dataSource" ref="dataSource" />
    <property name="mappingResources">
        <list>
            <value>Queries.hbm.xml</value>
        </list>
    </property>
    <property name="hibernateProperties">
        <props>
            <prop key="dialect">org.hibernate.dialect.Oracle10gDialect</prop>
        </props>
    </property>
    -->
</bean>

如果您正在使用JPA注释类，则可以使用AnnotationSessionFactoryBean而不是LocalSessionFactoryBean，并将类直接注入Spring bean：

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="annotatedClasses">
       <list>
           <value>com.company.app.common.model.Account</value>
           <value>com.company.app.common.model.AccountCategory</value>
           <value>com.company.app.common.model.AssetType</value>
           <value>com.company.app.common.model.Book</value>
           <value>com.company.app.model.AssetTypeCategory</value>      
       </list>
    </property>
    <property name="mappingResources">
       <list>
          <value>Queries.hbm.xml</value>
       </list>
    </property>        
    <property name="hibernateProperties">
        <props>
            <prop key="dialect">org.hibernate.dialect.Oracle10gDialect</prop>
        </props>
    </property>
</bean>

作为skaffman的answer的略微变化，我使用了类packagesToScan的属性AnnotationSessionFactoryBean来避免列出所有单个模型类名称：

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="packagesToScan">
       <list>
           <value>com.company.app.common.model</value>
       </list>
    </property>
    <property name="mappingResources">
       <list>
          <value>Queries.hbm.xml</value>
       </list>
    </property>        
    <property name="hibernateProperties">
        <props>
            <prop key="dialect">org.hibernate.dialect.Oracle10gDialect</prop>
        </props>
    </property>
</bean>

我从优秀的书Spring in Action, Third Edition中了解了这个属性。

我也遇到了同样的问题，这对我有用 -

<bean id="auditCoreSessionFactory"
    class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
    <property name="dataSource">
        <ref bean="auditCoreDataSource" />
    </property>
    <property name="packagesToScan" value="com.odeon.audit.dao.entity" />
    <property name="annotatedClasses">
        <list>
            <value>com.odeon.audit.dao.entity.AuditLogEntity</value>
            <value>com.odeon.audit.dao.entity.AuditLogApplicationEtity</value>
            <value>com.odeon.audit.dao.entity.AuditLogModuleEntity</value>
            <value>com.odeon.audit.dao.entity.AuditLogOperationEntity</value>
        </list>
    </property>
    <property name="hibernateProperties">
        <props>
            <prop key="hibernate.dialect">#{auditCoreProp.getString('jdbc.dialect')}</prop>
            <prop key="hibernate.show_sql">#{auditCoreProp.getString('jdbc.show_sql')}</prop>
            <prop key="hbm2ddl.auto">#{auditCoreProp.getString('jdbc.hbm2ddl.auto')}
            </prop>
            <!-- prop key="hibernate.hbm2ddl.auto">create</prop -->
        </props>
    </property>
</bean>

如何将Hibernate类映射转换为Spring应用程序上下文？
