如何使用Spring 4配置Hibernate 5

标签: java spring hibernate orm hibernate-5.x

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?

2 个答案:

答案 0 :(得分:10)

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

答案 1 :(得分:8)

@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。
