Error creating bean with name ‘sessionFactory’ defined in ServletContext resource 異常處理

在SSH整合時常出現這個異常:

嚴重: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in ServletContext resource [/WEB-INF/classes/applicationContext.xml]: Invocation of init method failed; nested exception is org.hibernate.MappingException: An AnnotationConfiguration instance is required to use <mapping class="com.wjl.personalspace.model.User"/>

解決方案：

1.HibernateSessionFactory中Configuration configuration = new Configuration();是否改為Configuration configuration = new AnnotationConfiguration();

2.刪除項目中重複的jar包和asm-2.3.2.jar （asm.jar與asm-2.3.2.jar衝突）

3.applicationContext.xml中XXXDao是否加入<property name="sessionFactory" ref="sessionFactory"></property>

4.如果實體類採用註解的方式映射資料庫，則applicationContext.xml中sessionFactory為

<bean id="sessionFactory"

class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">

<property name="configLocation"

value="classpath:hibernate.cfg.xml">

</property>

</bean>

注意class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"

而不是class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"
