sessionFactory or hibernateTemplate is required

我把Spring和Hibernate整合起来时，遇到个错误搞了好久，按照网上的方法也没法解决

抛出错误如下：

严重: 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 'userService' defined in ServletContext resource [/WEB-INF/applicationContext.xml]: Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: 'sessionFactory' or 'hibernateTemplate' is required

	<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) {

		......
	}

}

 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>

 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");   
        }   
    }  

 
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>
