问题描述

道歉，因为我对Spring比较陌生。我有以下代码...



org.assessme.com.dao.UserDAOImpl.java 

  @Repository 
 public class UserDAOImpl implements UserDAO {
 
 
 @Autowired 
 private SessionFactory sessionFactory; 
 
 
 @Transactional 
 public User getById（Long id）{
 return（User）sessionFactory.getCurrentSession（）。load（User.class，id）; 
} 
 
}

这个使用org.assessme.com .dao.UserDAO.java 

  public interface UserDAO {
 public User getById（Long id）; 
}

当我尝试运行我的程序时，我得到... 

  ERROR：org.springframework.web.servlet.DispatcherServlet  - 上下文初始化失败

我的春天.xml是...

任何人都可以看到我做错了吗？我不太清楚如何自动装载sessionFactory。



我的实体类如下...



org.assessme.com.entity.User.java 

  @Entity 
 @Table（name =users ）
 public class User {
 
 @Column（name =firstName）
 private String firstName; 
 
 @Column（name =lastName）
 private String lastName; 
 
 @Column（name =email）
 private String email; 
 
 @Id 
 @GeneratedValue（strategy = GenerationType.AUTO）
 @Column（name =id）
私人长ID; 
 
 
 public String getFirstName（）{
 return firstName; 
} 
 public void setFirstName（String firstName）{
 this.firstName = firstName; 
} 
 public String getLastName（）{
 return lastName; 
} 
 public void setLastName（String lastName）{
 this.lastName = lastName; 
} 
 public String getEmail（）{
 return email; 
} 
 public void setEmail（String email）{
 this.email = email; 
} 
 public long getId（）{
 return id; 
} 
 public void setId（long id）{
 this.id = id; 
 
 
 
 
 $ b 
谢谢，
 
 
顺便说一下，我在springmvc中使用它，应该在servlet-context.xml中吗？
错误消息的相关部分： 
 
 
  NoSuchBeanDefinitionException：没有匹配[org.hibernate.SessionFactory]类型的bean， 
  
问题是 AnnotationSessionFactoryBean 没有实现 org.hibernate.SessionFactory 接口。要获得需要调用 buildSessionFactory 方法。
 
Apologies as I'm relatively new to Spring.  I have the following code...



org.assessme.com.dao.UserDAOImpl.java
@Repository
public class UserDAOImpl implements UserDAO{


    @Autowired
    private SessionFactory sessionFactory;


     @Transactional
    public User getById(Long id) {
        return (User) sessionFactory.getCurrentSession().load(User.class, id);
    }

}

This uses org.assessme.com.dao.UserDAO.java
public interface UserDAO {
    public User getById(Long id);
}

When I try to run my program, I get...
ERROR: org.springframework.web.servlet.DispatcherServlet - Context initialization failed

</beans>

Can anyone see what I'm doing incorrectly?  I'm not quite sure how to autowire the sessionFactory.



My entity class is as follows...



org.assessme.com.entity.User.java
@Entity
@Table(name = "users")
public class User {

    @Column(name = "firstName")
    private String firstName;

    @Column(name = "lastName")
    private String lastName;

    @Column(name = "email")
    private String email;

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    @Column(name = "id")
    private long id;


    public String getFirstName() {
        return firstName;
    }
    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }
    public String getLastName() {
        return lastName;
    }
    public void setLastName(String lastName) {
        this.lastName = lastName;
    }
    public String getEmail() {
        return email;
    }
    public void setEmail(String email) {
        this.email = email;
    }
    public long getId() {
        return id;
    }
    public void setId(long id) {
        this.id = id;
    }
}

Thanks,



I'm using this in springmvc by the way, should this be in servlet-context.xml?
 解决方案 
Here is the relevant part of the error message:
NoSuchBeanDefinitionException: No matching bean of type [org.hibernate.SessionFactory]

The problem is AnnotationSessionFactoryBean does not implement the org.hibernate.SessionFactory interface.  To get one of those you need to call the buildSessionFactory method.
