Hibernate 4在sessionFactory创建时出错 [英] Hibernate 4 Error on sessionFactory creation

问题描述

 在从3.v升级到Hibernate 4的过程中，我遇到了在启动TC时发生的这个问题。 ...在ServletContext资源[/WEB-INF/spring/app-config.xml]中定义名称为'sessionFactory'的Bean时创建错误：调用init方法失败;嵌套的异常是在在org.springframework.beans.factory.annotation org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor $ AutowiredFieldElement.inject（AutowiredAnnotationBeanPostProcessor.java:506）

如何解决这个问题？

解决方案

请替换 org.springframework.orm.hibernate4.LocalSessionFactoryBuilder 而不是 org.springframework.orm.hibernate4。 LocalSessionFactoryBean的。这可能有帮助。

During upgrading to Hibernate 4 from its 3.v, I run into this problem occurred at the TC starting up.

And the sessionFactory in my configuration file is done as the following:

<bean id="sessionFactory"
    class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="mappingResources">
        <list>
            <value>shippingCharge.hbm.xml</value>
        </list>
    </property>
    <property name="annotatedClasses">
        <list>
            <value>com.abc.myapp.account.domain.ProfileInfo</value>
            <value>com.abc.myapp.account.domain.Profile</value>
        </list>
    </property>
    <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">${hibernate.format_sql}</prop>
            <prop key="hibernate.generate_statistics">${hibernate.generate_statistics}</prop>
            <prop key="hibernate.ejb.naming_strategy">org.hibernate.cfg.DefaultComponentSafeNamingStrategy
            </prop>
        </props>
    </property>
    <!--  removed for hibernate 4. any replacement?
    <property name="eventListeners">
        <map>
            <entry key="merge">
                <bean
                    class="org.springframework.orm.hibernate3.support.IdTransferringMergeEventListener" />
            </entry>
        </map>
    </property>
    -->
</bean>

How to solve this problem?

解决方案

Please replace org.springframework.orm.hibernate4.LocalSessionFactoryBuilder instead of org.springframework.orm.hibernate4.LocalSessionFactoryBean. This might help.
