使用java持久性API集成Spring Hibernate？

我正在使用Spring3和Hibernate4。我有下面的配置来使用spring和hibernate

<bean name="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource"/>
    <property name="annotatedClasses">
        <list>
            <value>com.rsat.Employee</value>
        </list>
    </property>
    <property name="hibernateProperties">
        <props>
            <prop key="hibernate.cache.provider_class">org.hibernate.cache.NoCacheProvider</prop>
            <prop key="hibernate.dialect">org.hibernate.dialect.OracleDialect</prop>
            <prop key="hibernate.show_sql">true</prop>
            <prop key="hibernate.format_sql">true</prop>
            <prop key="hibernate.use_sql_comments">true</prop>
            <prop key="hibernate.jdbc.batch_size">50</prop>
            <!-- Added to mask bean relational constraint validation error -->
            <prop key="javax.persistence.validation.mode">none</prop>
        </props>
    </property>
</bean>

 <bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory"/>
</bean>

<!-- Hibernate Transaction manager for US data source -->
<tx:annotation-driven transaction-manager="transactionManager" />

pom依赖性 Employee.java 以上配置工作正常，没有任何问题

<bean name="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource"/>
    <property name="annotatedClasses">
        <list>
            <value>com.rsat.Employee</value>
        </list>
    </property>
    <property name="hibernateProperties">
        <props>
            <prop key="hibernate.cache.provider_class">org.hibernate.cache.NoCacheProvider</prop>
            <prop key="hibernate.dialect">org.hibernate.dialect.OracleDialect</prop>
            <prop key="hibernate.show_sql">true</prop>
            <prop key="hibernate.format_sql">true</prop>
            <prop key="hibernate.use_sql_comments">true</prop>
            <prop key="hibernate.jdbc.batch_size">50</prop>
            <!-- Added to mask bean relational constraint validation error -->
            <prop key="javax.persistence.validation.mode">none</prop>
        </props>
    </property>
</bean>

 <bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory"/>
</bean>

<!-- Hibernate Transaction manager for US data source -->
<tx:annotation-driven transaction-manager="transactionManager" />

但是现在我被要求使用HibernateJPA和persistence.xml

<bean name="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource"/>
    <property name="annotatedClasses">
        <list>
            <value>com.rsat.Employee</value>
        </list>
    </property>
    <property name="hibernateProperties">
        <props>
            <prop key="hibernate.cache.provider_class">org.hibernate.cache.NoCacheProvider</prop>
            <prop key="hibernate.dialect">org.hibernate.dialect.OracleDialect</prop>
            <prop key="hibernate.show_sql">true</prop>
            <prop key="hibernate.format_sql">true</prop>
            <prop key="hibernate.use_sql_comments">true</prop>
            <prop key="hibernate.jdbc.batch_size">50</prop>
            <!-- Added to mask bean relational constraint validation error -->
            <prop key="javax.persistence.validation.mode">none</prop>
        </props>
    </property>
</bean>

 <bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory"/>
</bean>

<!-- Hibernate Transaction manager for US data source -->
<tx:annotation-driven transaction-manager="transactionManager" />

你能告诉我推荐哪种方法吗？另外，如何使用Hibernate JPA

<bean name="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource"/>
    <property name="annotatedClasses">
        <list>
            <value>com.rsat.Employee</value>
        </list>
    </property>
    <property name="hibernateProperties">
        <props>
            <prop key="hibernate.cache.provider_class">org.hibernate.cache.NoCacheProvider</prop>
            <prop key="hibernate.dialect">org.hibernate.dialect.OracleDialect</prop>
            <prop key="hibernate.show_sql">true</prop>
            <prop key="hibernate.format_sql">true</prop>
            <prop key="hibernate.use_sql_comments">true</prop>
            <prop key="hibernate.jdbc.batch_size">50</prop>
            <!-- Added to mask bean relational constraint validation error -->
            <prop key="javax.persistence.validation.mode">none</prop>
        </props>
    </property>
</bean>

 <bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory"/>
</bean>

<!-- Hibernate Transaction manager for US data source -->
<tx:annotation-driven transaction-manager="transactionManager" />

谢谢

JPA并不是Hibernate的真正替代品。JPA是ORM（对象关系映射）的通用规范。与Java中的其他子技术一样，一旦许多供应商开始发明类似的东西，Java社区就试图创建一个规范来标准化它。Hibernate的最新版本确实实现了JPA规范（以及EclipseLink/DataNucleus/。来命名其他规范）

<bean name="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource"/>
    <property name="annotatedClasses">
        <list>
            <value>com.rsat.Employee</value>
        </list>
    </property>
    <property name="hibernateProperties">
        <props>
            <prop key="hibernate.cache.provider_class">org.hibernate.cache.NoCacheProvider</prop>
            <prop key="hibernate.dialect">org.hibernate.dialect.OracleDialect</prop>
            <prop key="hibernate.show_sql">true</prop>
            <prop key="hibernate.format_sql">true</prop>
            <prop key="hibernate.use_sql_comments">true</prop>
            <prop key="hibernate.jdbc.batch_size">50</prop>
            <!-- Added to mask bean relational constraint validation error -->
            <prop key="javax.persistence.validation.mode">none</prop>
        </props>
    </property>
</bean>

 <bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory"/>
</bean>

<!-- Hibernate Transaction manager for US data source -->
<tx:annotation-driven transaction-manager="transactionManager" />

在JPA上使用Hibernate的好处是您的代码符合标准。因此，如果以后出于任何原因决定更改ORM供应商，您可以通过最少的代码重构来完成（因为其他供应商也会（应该）遵守标准）

<bean name="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource"/>
    <property name="annotatedClasses">
        <list>
            <value>com.rsat.Employee</value>
        </list>
    </property>
    <property name="hibernateProperties">
        <props>
            <prop key="hibernate.cache.provider_class">org.hibernate.cache.NoCacheProvider</prop>
            <prop key="hibernate.dialect">org.hibernate.dialect.OracleDialect</prop>
            <prop key="hibernate.show_sql">true</prop>
            <prop key="hibernate.format_sql">true</prop>
            <prop key="hibernate.use_sql_comments">true</prop>
            <prop key="hibernate.jdbc.batch_size">50</prop>
            <!-- Added to mask bean relational constraint validation error -->
            <prop key="javax.persistence.validation.mode">none</prop>
        </props>
    </property>
</bean>

 <bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory"/>
</bean>

<!-- Hibernate Transaction manager for US data source -->
<tx:annotation-driven transaction-manager="transactionManager" />

网上有很多关于如何在Spring中使用JPA/Hibernate的教程。当我第一次开始时，一个有用的方法是检查SpringRoo项目——这是一个代码生成器工具，可以构建一个随时可用的SpringMVC/JPA/Hibernate代码项目。从那里您可以检查配置和设置。

Hibernate是JPA的JPA实现。

<bean name="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource"/>
    <property name="annotatedClasses">
        <list>
            <value>com.rsat.Employee</value>
        </list>
    </property>
    <property name="hibernateProperties">
        <props>
            <prop key="hibernate.cache.provider_class">org.hibernate.cache.NoCacheProvider</prop>
            <prop key="hibernate.dialect">org.hibernate.dialect.OracleDialect</prop>
            <prop key="hibernate.show_sql">true</prop>
            <prop key="hibernate.format_sql">true</prop>
            <prop key="hibernate.use_sql_comments">true</prop>
            <prop key="hibernate.jdbc.batch_size">50</prop>
            <!-- Added to mask bean relational constraint validation error -->
            <prop key="javax.persistence.validation.mode">none</prop>
        </props>
    </property>
</bean>

 <bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory"/>
</bean>

<!-- Hibernate Transaction manager for US data source -->
<tx:annotation-driven transaction-manager="transactionManager" />

因此，只要您坚持JPA标准，并避免特定于hibernate，您就可以了。 首先用JPA等效的EntityManagerFactory替换会话工厂定义

<bean name="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource"/>
    <property name="annotatedClasses">
        <list>
            <value>com.rsat.Employee</value>
        </list>
    </property>
    <property name="hibernateProperties">
        <props>
            <prop key="hibernate.cache.provider_class">org.hibernate.cache.NoCacheProvider</prop>
            <prop key="hibernate.dialect">org.hibernate.dialect.OracleDialect</prop>
            <prop key="hibernate.show_sql">true</prop>
            <prop key="hibernate.format_sql">true</prop>
            <prop key="hibernate.use_sql_comments">true</prop>
            <prop key="hibernate.jdbc.batch_size">50</prop>
            <!-- Added to mask bean relational constraint validation error -->
            <prop key="javax.persistence.validation.mode">none</prop>
        </props>
    </property>
</bean>

 <bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory"/>
</bean>

<!-- Hibernate Transaction manager for US data source -->
<tx:annotation-driven transaction-manager="transactionManager" />

<bean id="emf"
class="org.springframework.orm.jpa.LocalEntityManagerFactoryBean">
<property name="persistenceUnitName" value="puName" />
</bean>

如果您将persistence.xml放在/META-INF/下，它应该可以开箱即用。 您的transactionManager也应该进行调整。查看文档

@Enttity已经兼容jpa了

Hibernate是第一个成为市场领导者的ORM框架之一。当Hibernate引入市场时，没有为ORM解决方案定义JPA规范。在看到HibernateAPI的优点之后，Java社区为持久性机制中的所有问题创建了一个通用规范

<bean name="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource"/>
    <property name="annotatedClasses">
        <list>
            <value>com.rsat.Employee</value>
        </list>
    </property>
    <property name="hibernateProperties">
        <props>
            <prop key="hibernate.cache.provider_class">org.hibernate.cache.NoCacheProvider</prop>
            <prop key="hibernate.dialect">org.hibernate.dialect.OracleDialect</prop>
            <prop key="hibernate.show_sql">true</prop>
            <prop key="hibernate.format_sql">true</prop>
            <prop key="hibernate.use_sql_comments">true</prop>
            <prop key="hibernate.jdbc.batch_size">50</prop>
            <!-- Added to mask bean relational constraint validation error -->
            <prop key="javax.persistence.validation.mode">none</prop>
        </props>
    </property>
</bean>

 <bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory"/>
</bean>

<!-- Hibernate Transaction manager for US data source -->
<tx:annotation-driven transaction-manager="transactionManager" />

Hibernate提供了称为Hibernate JPA的JPA实现。不同的是，JPA实现必须符合规范，但供应商解决方案将有自己的API（有时会为您的应用程序提供附加值）。为了将来的利益，总是建议使用标准API，如JPA

<bean name="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource"/>
    <property name="annotatedClasses">
        <list>
            <value>com.rsat.Employee</value>
        </list>
    </property>
    <property name="hibernateProperties">
        <props>
            <prop key="hibernate.cache.provider_class">org.hibernate.cache.NoCacheProvider</prop>
            <prop key="hibernate.dialect">org.hibernate.dialect.OracleDialect</prop>
            <prop key="hibernate.show_sql">true</prop>
            <prop key="hibernate.format_sql">true</prop>
            <prop key="hibernate.use_sql_comments">true</prop>
            <prop key="hibernate.jdbc.batch_size">50</prop>
            <!-- Added to mask bean relational constraint validation error -->
            <prop key="javax.persistence.validation.mode">none</prop>
        </props>
    </property>
</bean>

 <bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory"/>
</bean>

<!-- Hibernate Transaction manager for US data source -->
<tx:annotation-driven transaction-manager="transactionManager" />

如果您正在寻找集成方法，这篇关于的文章可能会有所帮助

    <property name="dataSource" ref="dataSource"/>
    <property name="annotatedClasses">

因为Hibernate是JPA规范的一个实现，所以如果您想使用它，您应该只关注配置。您不应该在DAO类中直接使用它。在DAO类中，您应该只使用JPA

<bean name="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource"/>
    <property name="annotatedClasses">
        <list>
            <value>com.rsat.Employee</value>
        </list>
    </property>
    <property name="hibernateProperties">
        <props>
            <prop key="hibernate.cache.provider_class">org.hibernate.cache.NoCacheProvider</prop>
            <prop key="hibernate.dialect">org.hibernate.dialect.OracleDialect</prop>
            <prop key="hibernate.show_sql">true</prop>
            <prop key="hibernate.format_sql">true</prop>
            <prop key="hibernate.use_sql_comments">true</prop>
            <prop key="hibernate.jdbc.batch_size">50</prop>
            <!-- Added to mask bean relational constraint validation error -->
            <prop key="javax.persistence.validation.mode">none</prop>
        </props>
    </property>
</bean>

 <bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory"/>
</bean>

<!-- Hibernate Transaction manager for US data source -->
<tx:annotation-driven transaction-manager="transactionManager" />

以下是配置Hibernate的步骤：

1.persistence.xml

<bean name="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource"/>
    <property name="annotatedClasses">

gerrytan，谢谢你的回答。那么，您建议使用EntityManager而不是SessionFactory吗？Sessionfactory是否特定于Hibernate？谢谢正确，如果您查看完整的类名SessionFactory以org.hibernate开头，而所有JPA类都以javax.persistence开头。任何与org.hibernate有关的内容都是特定于hibernate的。我不能提出任何建议，你需要了解利弊并做出决定。有些人坚持使用Hibernate以避免学习其他新东西，而另一些人则坚持使用JPA，以防出现比Hibernate更好的东西，或者他们希望轻松地切换到其他供应商。就我个人而言，我会忍受痛苦，继续学习JPA。无论如何，程序员都必须终身学习。
