Question

我正在尝试使用Spring-Hibernate集成的示例应用程序。但是，当我加载config.xml

时，我收到此错误

Exception in thread "main" org.springframework.beans.factory.CannotLoadBeanClassException: Error loading class [org.springframework.orm.hibernate3.LocalSessionFactoryBean] for bean with name 'mySessionFactory' defined in class path resource [SpringDAO/config.xml]: problem with class file or dependent class; nested exception is java.lang.NoClassDefFoundError: org/springframework/dao/support/PersistenceExceptionTranslator

这是我的config.xml代码

        <property name="hibernateProperties">

    </bean>

    <bean id="hibernateTemplate"
        class="org.springframework.orm.hibernate3.HibernateTemplate">
        <property name="sessionFactory">
            <ref bean="mySessionFactory"/>
        </property>
    </bean>

    <bean id="socketStreamedDataDAO">
        <property name="hibernateTemplate">
            <ref bean="hibernateTemplate"/>
        </property>
    </bean>
</beans>

可能有mappingResources属性类错误或其他问题。但是，我已经指定了那个hibernate xml配置的完整类路径。那可能是什么问题呢？请帮帮我。

Answer 1

java.lang.NoClassDefFoundError的来源大部分时间都是类路径中的问题。在这里，您必须检查类路径中是否存在Spring TX和Hibernate。

Answer 2

请在你的类路径中添加spring tx jar。我遇到了同样的问题，并通过添加spring-tx jar来解决。
