我是Spring MVC的初学者.我遇到了一个问题“找不到类型为[org.hibernate.SessionFactory]的匹配bean依赖：预计至少有一个bean可以作为此依赖项的autowire候选者.”并花了很多时间.
我使用了maven构建管理.我的项目有一个项目,包括2个模块：springcore(jar)和springmvc(web app).而springmvc(网络应用程序)一直是依赖弹簧的核心.在模块spring核心中,我定义了所有包,如dom,dao,service及其实现,我还在src / main / resources中定义了applicationContext.xml：
applicationContext.xml中
ContactDaoImpl.java
@Repository
public class ContactDaoImpl implements ContactDao {
private Log log = LogFactory.getLog(ContactDaoImpl.class);
@Autowired
private SessionFactory sessionFactory;
public List
ContactServiceImpl.java
@Service
@Transactional
public class ContactServiceImpl implements ContactService {
@Autowired
private ContactDao contactDao;
@Transactional(propagation=Propagation.REQUIRED)
public List
在springmvc(web app)中,我定义了web.xml和dispatcher-servlet.xml
调度员servlet.xml中
web.xml中
当我尝试在Tomcat 6.0服务器中运行它时,这是我的问题

有人能告诉我,当我配置SessionFactory时,Web应用程序上下文无法创建SessionFactory或者出现任何问题的原因是什么.
任何支持将不胜感激.
一般问题是从类路径中缺少配置/类,无论您自己的库.再次检查导入和配置是否正确：
>使用类路径扫描来实现实体类的自动检测：
< bean id =“sessionFactory”class =“org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean”>
< property name =“dataSource”ref =“dataSource”/>
< property name =“packagesToScan”value =“test.package”/>
< /豆腐>
>或者最重要的是：AnnotationSessionFactoryBean类需要Hibernate 3.2或更高版本,并且存在Java Persistence API和Hibernate Annotations附加组件.
