关于ssh搭配框架问题

Question

小弟、刚学ssh所以不是很理解。就按照老实讲的步骤来的。但是其实不是很理解写的那些配置文件都是什么意思。不废话。遇到个问题求助。
我在spring配置文件applicationContext.xml中配置关联了两个实体类
<!-- 配置dao -->
<bean id="userdao" class="dao.impl.UserDaoImpl">
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>
<bean id="bookdao" class="dao.impl.BookDaoImpl">
<property name="sessionFactory" ref="sessionFactory"></property>
</bean> <!-- 配置biz -->
<bean id="userbiz" class="biz.impl.UserBizImpl">
<property name="userDao" ref="userdao"></property>
</bean>
<bean id="bookbiz" class="biz.impl.BookBizImpl">
<property name="bookdao" ref="bookdao"></property>
</bean> <!-- 配置action -->
<bean id="useraction" class="action.UserAction">
<property name="userBiz" ref="userbiz"></property>
</bean>
<bean id="bookaction" class="action.BookAction">
<property name="bookBiz" ref="bookbiz"></property>
</bean>
但是启动tomcat就报错。郁闷。错误信息如下

很郁闷啊。如果只是配置一个userbiz就能正常运行。两个的花就报错了。求大神帮助。果断给分

Answer 1

<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"
>
<property name="configLocation"
value="file:src/hibernate.cfg.xml">
</property>
</bean>
<bean name="hibernateTemplate" class="org.springframework.orm.hibernate3.HibernateTemplate" >
<property name="sessionFactory" ref="sessionFactory" >
</property>
</bean>有这个东西吗

Answer 2

抱歉。刚在吃饭没看到那些都有的。是不是因为我配置了两个biz才报的错？如果我去掉一个只留userbiz登录就能成功

Answer 3

把你运行错误的代码提出来，“是不是因为我配置了两个biz才报的错” 两个biz ？ 这个是怎么配置的？贴出来看看。

Answer 5

感谢帮忙想问题。。已经知道问题了。我的实现biz接口的实现类extends了HibernateDaoSupport所以报错了。。
