报错信息显示是在创建名为'hibernateuserdao'的bean时出现了问题。具体的错误信息是'sessionFactory' or 'hibernateTemplate' is required，意味着在创建HibernateUserDao bean时，Spring发现缺少必需的sessionFactory或hibernateTemplate。

---

在你的applicationContext.xml文件中，你已经配置了sessionFactory bean：

<bean id="sessionFactory"
    class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
    <!-- 配置省略 -->
</bean>

但是，在配置HibernateUserDao bean时，你没有指定hibernateTemplate。你可以通过以下方式之一来解决这个问题：

1. 添加hibernateTemplate属性到HibernateUserDao bean的配置中：

   <bean id="hibernateuserdao" class="com.dao.HibernateUserDao" init-method="">
       <property name="sessionfactory" ref="sessionFactory"></property>
       <property name="hibernateTemplate" ref="hibernateTemplate"></property>
   </bean>
   

   请注意，你需要确保在配置文件中还有一个hibernateTemplate bean 的定义。通常情况下，你可以这样定义：

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

2. 使用HibernateDaoSupport提供的setSessionFactory方法设置sessionFactory属性：

   在HibernateUserDao类中，使用setSessionFactory方法设置sessionFactory属性：

   public class HibernateUserDao extends HibernateDaoSupport implements UserDao {
       // 省略其他代码
   
       public HibernateUserDao(SessionFactory sessionFactory) {
           setSessionFactory(sessionFactory);
       }
   
       // 省略其他代码
   }
   

   然后在applicationContext.xml中配置HibernateUserDao bean时，通过构造函数传递sessionFactory：

   <bean id="hibernateuserdao" class="com.dao.HibernateUserDao">
       <constructor-arg ref="sessionFactory" />
   </bean>
   

无论哪种方式，确保HibernateUserDao 在初始化时能够获取到sessionFactory 或 hibernateTemplate。

这个报错是因为在HibernateUserDao类中，sessionFactory和hib这个报错是因为在HibernateUserDao类中，sessionFactory和hibernateTemplate没有被正确注入。你需要在HibernateUserDao类中添加这两个属性的setter方法，并在applicationContext.xml文件中将它们注入到HibernateUserDao`类的实例中。

---

首先，在HibernateUserDao类中添加setter方法：

public void setSessionfactory(SessionFactory sessionfactory) {
    this.sessionfactory = sessionfactory;
}

public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {
    this.hibernateTemplate = hibernateTemplate;
}

然后，在applicationContext.xml文件中将它们注入到HibernateUserDao类的实例中：

<bean id="hibernateuserdao" class="com.dao.HibernateUserDao">
    <property name="sessionfactory" ref="sessionFactory"></property>
    <property name="hibernateTemplate" ref="hibernateTemplate"></property>
</bean>

这样应该可以解决报错问题。
