spring+hibernate整合时出现的错误

刚接触SSH框架，学习的过程中一动手就是各种bug，在此记录一下bug

。

Bug1:使用spring4.1.0+hibernate3.0.5出现如下异常

Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'catDao' defined in class path resource [applicationContext.xml]: Cannot resolve reference to bean 'sessionFactory' while setting bean property 'sessionFactory'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in class path resource [applicationContext.xml]: Initialization of bean failed; nested exception is java.lang.NoClassDefFoundError: org/hibernate/cache/RegionFactory

hibernate的实体类是使用xml文件配置的，配置如下：

<!-- 使用xml映射实体类 -->
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean" destroy-method="destroy">
<property name="dataSource" ref="dataSource"></property>
<!-- <property name="configLocation" value="classpath:hibernate.cfg.xml"></property> --> <!-- 1.加载hibernate的配置文件 -->
org.hibernate.cache.RegionFactory<property name="mappingLocations" value="classpath:/com/hibernate/dao/*.hbm.xml"></property>
<property name="hibernateProperties">  <!--  2.直接在spring配置文件中配置hibernate （2和1选一种） -->
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.format_sql">true</prop>
<prop key="hibernate.hbm2ddl.auto">update</prop>
</props>
</property>
</bean>

网上百度了一大圈，尝试了一大堆方法，最终看到一位说是hibernate3.0版本压根就没有这个org.hibernate.cache.RegionFactory类，因此最后把hibernate3.0.5版本换成3.3.2版本问题就解决了

。如果

hibernate某版本的各种包都加载了，还是报这种没有类的错误很可能是版本的问题。

Bug2：xml配置实体麻烦，就想用注解方式配置实体类，一动手又掉坑里了，使用spring4.1.0+hibernate3.3.2，异常如下：

org.hibernate.cfg.Configuration.addAnnotatedClass(Ljava/lang/Class;)Lorg/hibernat又百度最终还是版本问题

，把hibernate最终换4.1.0版本就好了。底子太弱，一走一个坑！！！
