我整天都在努力寻找解决方案，但无济于事。我试图在我的一个DAO类中自动装配sessionFactory bean。这是我的DAO：
@Repository("userDao")
public class UserDaoImpl implements UserDao {
@Autowired
private SessionFactory sessionFactory;
//This is where it goes wrong, he can not autowire this bean
public UserDaoImpl(){}
public Session getCurrentSession() {
return sessionFactory.getCurrentSession();
}
@Override
public void saveUser(User user){
getCurrentSession().saveOrUpdate(user);
}
public SessionFactory getSessionFactory() {
return sessionFactory;
}
public void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
}
}
这是我的applicationContext.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

<!-- Hibernate Session Factory -->
<!-- This is what he cannot find -->
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<!-- this used to be a bean of type LocalSessionFactoryBean but I read that if you use annotations you should use this one instead -->
<property name="dataSource" ref="dataSource"/>
<property name="packagesToScan">

<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.hbm2ddl.auto">create</prop>
</props>
</property>
<property name="annotatedClasses">
<list>
<value>com.robin.model.User</value>
</list>
</property>
</bean>
<!-- The only thing in here is the driver for mysql-->
<tx:annotation-driven transaction-manager="transactionManager"/>
<bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory"/>
</bean>
<import resource="mysql-context.xml"/>
</beans>
我已尝试使用@Resource和@Qualifier("sessionFactory")注释sessionFactory，正如另一个线程中所建议的那样，我现在可以从那里导航到正确的bean，但是当我运行它时，他仍然没有自动装配这个。
这是我的web.xml文件：
<web-app version="3.0"

答案 0 :(得分：3)
我通过将sessionFactory bean升级为hibernate 4解决了这个问题class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"应该在那里而不是class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"
答案 1 :(得分：0)
将hibernate-core jar添加到您的依赖项中（版本取决于其他框架＆＃39;涉及的版本）
答案 2 :(得分：0)
您已通过检查是否已包含所有spring配置文件来解决此问题。
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring.xml,classpath:spring-hibernate.xml</param-value>
</context-param>
然后， 检查是否已正确配置sessionfactory，下面是我的配置。
<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="hibernateProperties">
<props>
<prop key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl.auto}</prop>
<prop key="hibernate.dialect">${hibernate.dialect}</prop>
<prop key="hibernate.show_sql">${hibernate.show_sql}</prop>
<prop key="hibernate.format_sql">${hibernate.format_sql}</prop>
</props>
</property>
<property name="packagesToScan">
<list>
<value>com.gya.model</value>
</list>
</property>
</bean>
<bean name="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>
最后，如果您使用maven，请检查您的pom.xml。 它是否包含
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-orm</artifactId>
<version>3.1.2.RELEASE</version>
</dependency>
