Spring HIbernate 整合问题

[wuhanliming]

测试出错，请大家帮我看看怎么回事：
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userService': Injection of resource methods failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'us': Injection of resource methods failed; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No unique bean of type [org.hibernate.SessionFactory] is defined: Unsatisfied dependency of type [interface org.hibernate.SessionFactory]: expected at least 1 matching bean

Error creating bean with name 'us': 是由private UserDAO userDAO;创建出错引出userService创建异常！ 所以先看看你的userDAO吧~！ 另外对注解方式不是很了解，你都注解了为什么还要用get/set方法呢？

是否加载顺序问题。 没有定义 sessionfactory ？

有加载AnnotationSessionFactoryBean啊。

[wuhanliming]

这是UserDAOImpl类的源码

package com.bjsxt.daoImpl;


import javax.annotation.Resource;

import org.hibernate.SessionFactory;
import org.springframework.stereotype.Component;

import com.bjsxt.dao.UserDAO;
import com.bjsxt.model.User;

@Component("us")
public class UserDAOImpl implements UserDAO {

	private SessionFactory session;
	
	public void save(User user) {
		
		System.out.println("user saved!");
	}

	@Resource
	public void setSession(SessionFactory session) {
		this.session = session;
	}

	public SessionFactory getSession() {
		return session;
	}
}

谢谢大神，我有点明白了，晚上回去，我把userdao源码贴上来。现在在学习阶段，用xml方式和annotation方式两种方式混合着用的。

这段代码不注释掉就不会出错了。

 <bean id="sessionFactory"
        class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="annotatedClasses">
            <list>
                <value>com.bjsxt.model.User</value>
            </list>
        </property>
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">
                    org.hibernate.dialect.MySQLDialect
                </prop>
                <prop key="hibernate.show_sql">true</prop>
            </props>
