Question

我想升级到Hibernate 5，但是出于某些奇怪的原因我无法让它工作。

Hibernate 4的弹簧上下文配置如下所示：

....
<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>

....

我遗漏了数据源和hibernateClasses bean定义。

对于Hibernate 5，我将包名改为hibernate5，如下所示：

....
<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，因为它无法找到LocalSessionFactoryBean类：-S。这个类驻留在spring-orm JAR中并且实际存在但是由于某种原因它无法找到并抛出以下异常：

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

有人知道我做错了吗？

Answer 1

可能你应该添加

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

我遇到了同样的问题，我的初始日志抱怨了，

java.lang.NoClassDefFoundError：javax / transaction / SystemException

Answer 2

@sapna回答正在发挥作用。

但是对于那些好奇的为什么它在hibernate 5.0.3.Final和5.0.4.Final之间断开，这里是答案：他们删除了对jta的依赖，这是：

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

此处描述了更改：HHH-10178

因此，如果您要从5.0.x升级到5.0.4或5.0.5并且希望不对类路径进行任何更改，则应该导入此lib而不是javax.transaction：jta one。

编辑：他们使用hibernte 5.0.7恢复了这一变化：HHH-10307，因此升级到此版本或更新版本也应解决此问题。
