sessionFactory or hibernateTemplate is required的解决办法【转】

今天自己在applicationXXX.xml配置文件中注入了一个实例，部署后重启tomcat时候抛错了，错误正是标题。我研究了好久，因为是参照之前注入成功的实例去注入的，怎么就出问题了呢？后来在网上查到，是因为我这个实例比较特殊：MemberDaoImpl extends HibernateDaoSupport implements MemberDao

就是因为集成了HibernateDaoSupport 这个，凡事继承这个的，都要在注入文件里面添加：<property name="sessionFactory" ref="sessionFactory"></property>

完整的部分是： <bean id="memberDao" class="cn.payeasy.user.service.impl.MemberDaoImpl">
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>

 

以下是网上的：

<bean id="userDAO" class="org.bookstore.dao.impl.UserDAO">
     <property name="sessionFactory" ref="sessionFactory"></property>
</bean>
<bean id="userService" class="org.bookstore.service.impl.UserService">
     <property name="userDAO">
         <ref bean="userDAO"/>
     </property>
</bean>

<bean id="userDAO" class="org.bookstore.dao.impl.UserDAO">
  <property name="sessionFactory" ref="sessionFactory"></property>
 </bean>
 <bean id="userService" class="org.bookstore.service.impl.UserService">
  <property name="userDAO">
   <ref bean="userDAO"/>
  </property>
 </bean>

 

 

public class UserDAO extends HibernateDaoSupport implements IUserDAO {

    public void saveUser(User user) {

         ......
     }

}

public class UserDAO extends HibernateDaoSupport implements IUserDAO {
 
 public void saveUser(User user) {

  ......
 }

}

修改后如下：

<bean id="userDAO" class="org.bookstore.dao.impl.UserDAO">
         <property name="sessionFactory" ref="sessionFactory"></property>
     </bean>
     <bean id="userService" class="org.bookstore.service.impl.UserService">
         <property name="userDAO">
             <ref bean="userDAO"/>
         </property>
         <property name="sessionFactory" ref="sessionFactory"></property>
     </bean>

<bean id="userDAO" class="org.bookstore.dao.impl.UserDAO">
  <property name="sessionFactory" ref="sessionFactory"></property>
 </bean>
 <bean id="userService" class="org.bookstore.service.impl.UserService">
  <property name="userDAO">
   <ref bean="userDAO"/>
  </property>
  <property name="sessionFactory" ref="sessionFactory"></property>
 </bean>

原因：

我的org.bookstore.dao.impl.UserDAO继承了org.springframework.orm.hibernate3.support.HibernateDaoSupport, spring在初始化容器的时候会对这个对象作一个check, 看下HibernateDaoSupport源码中的checkDaoConfig()方法就清楚啦:

protected final void checkDaoConfig() {
        if (this.hibernateTemplate == null) {
            throw new IllegalArgumentException("'sessionFactory' or 'hibernateTemplate' is required");
         }
     }

protected final void checkDaoConfig() {
        if (this.hibernateTemplate == null) {
            throw new IllegalArgumentException("'sessionFactory' or 'hibernateTemplate' is required");
         }
     }

protected final void checkDaoConfig() {   
        if (this.hibernateTemplate == null) {   
            throw new IllegalArgumentException("'sessionFactory' or 'hibernateTemplate' is required");   
        }   
    }

所以，在com.lfw.sh.manager.impl.UserManageImpl对象一定要注入一个sessionFactory or hibernateTemplate对象。

 

<bean id="sessionFactory"
        class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
         <property name="dataSource">
             <ref bean="dataSource" />
         </property>
         <property name="hibernateProperties">
             <props>
                 <prop key="hibernate.dialect">
                     org.hibernate.dialect.MySQLDialect
                 </prop>
             </props>
         </property>
         <property name="mappingResources">
             <list>
                 <value>org/bookstore/model/User.hbm.xml</value>
                 ....
             </list>
         </property>
     </bean>
