如何在Spring 4中配置Hibernate 5

Question

我想要升级到Hibernate 5，但由于某些奇怪的原因，我无法使它生效。

我的Spring上下文配置与Hibernate 4如下：

....
<bean id="sessionFactory"
    class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="annotatedClasses" ref="hibernateClasses" />
    <property name="hibernateProperties">
        <props>
            <prop key="hibernate.dialect">
                ${hibernate.dialect}
            </prop>
            <prop key="hibernate.show_sql">
                ${hibernate.show_sql}
            </prop>
            <prop key="hibernate.format_sql">true</prop>
            <prop key="hibernate.generate_statistics">
                ${hibernate.generate_statistics}
            </prop>
            <prop key="hibernate.hbm2ddl.auto">
                ${hibernate.hbm2ddl.auto}
            </prop>
        </props>
    </property>
</bean>

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

....

我省略了数据源和hibernateClasses bean的定义。

对于Hibernate 5，我将包名更改为类似于hibernate5的形式：

....
<bean id="sessionFactory"
    class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="annotatedClasses" ref="hibernateClasses" />
    <property name="hibernateProperties">
        <props>
            <prop key="hibernate.dialect">
                ${hibernate.dialect}
            </prop>
            <prop key="hibernate.show_sql">
                ${hibernate.show_sql}
            </prop>
            <prop key="hibernate.format_sql">true</prop>
            <prop key="hibernate.generate_statistics">
                ${hibernate.generate_statistics}
            </prop>
            <prop key="hibernate.hbm2ddl.auto">
                ${hibernate.hbm2ddl.auto}
            </prop>
        </props>
    </property>
</bean>

<bean id="transactionManager"
    class="org.springframework.orm.hibernate5.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory" />
</bean>

....

当我运行测试时，应用程序上下文无法启动，因为它找不到LocalSessionFactoryBean类 :-S。这个类驻留在spring-orm JAR中，实际上是存在的，但由于某种原因找不到它，并引发以下异常：

java.lang.NoClassDefFoundError: Could not initialize class org.springframework.orm.hibernate5.LocalSessionFactoryBuilder

有人知道我哪里做错了吗？

你的pom文件中的hibernate版本是什么？ - Brian Kates

我使用的版本是5.0.4.Final。 - Tranquilized

你的Spring版本是什么？我使用的是Spring 4.2.6和Hibernate 5.5.3配置，遇到了同样的问题。 - Shafin Mahmud

Answer 1

也许你应该添加。

<dependency>
  <groupId>javax.transaction</groupId>
  <artifactId>jta</artifactId>
  <version>1.1</version>
</dependency>

我遇到了同样的问题，我的初始日志显示如下错误：

java.lang.NoClassDefFoundError: javax/transaction/SystemException

该错误涉及到缺少javax/transaction/SystemException类。

Answer 2

@sapna的答案有效。

但是对于那些好奇为什么它在hibernate 5.0.3.Final和5.0.4.Final之间出现问题的人，这里是答案：他们删除了对jta的依赖，它原本是：

<dependency>
    <groupId>org.apache.geronimo.specs</groupId>
    <artifactId>geronimo-jta_1.1_spec</artifactId>
    <version>1.1.1</version>
    <scope>compile</scope>
</dependency>

变更内容在此处描述：HHH-10178

因此，如果您从5.0.x升级到5.0.4或5.0.5，并且希望不更改类路径中的任何内容，则应导入此库而不是javax.transaction：jta。

编辑： 他们通过hibernte 5.0.7撤销了这个更改：HHH-10307，因此升级到此版本或更新版本也应该修复此问题。
