如何使用注释在hibernate中实现映射？

I am trying to implement OneToMany and ManyToOne mapping in hibernate but I got error in dispatcher-servlet.xml while adding mapping class. 
It return error: 

> cvc-complex-type.2.4.a: Invalid content was found starting with 
> element 'mapping'. "http:// www.springframework.org/schema/beans"]}' 
> is expected.

调度-servlet.xml文件：如何使用注释在hibernate中实现映射？

<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> 
      <property name="driverClassName" value="${database.driver}" /> 
      <property name="url" value="${database.url}" /> 
      <property name="username" value="${database.user}" /> 
      <property name="password" value="${database.password}" />  
     </bean> 

     <bean id="sessionFactory" 
      class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"> 
      <property name="dataSource" ref="dataSource" /> 
      <property name="annotatedClasses"> 
      <list> 
      <value>com.tushar.hibernate.model.User</value> 
      <value>com.tushar.hibernate.model.Sender</value> 
      </list> 
      </property> 
      <property name="hibernateProperties"> 
      <props> 
      <prop key="hibernate.dialect">${hibernate.dialect}</prop> 
      <prop key="hibernate.show_sql">${hibernate.show_sql}</prop> 
      <prop key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl.auto}</prop> 
      <prop key="hibernate.c3p0.max_statements">${connectionpool.maximum.statements}</prop> 
      </props> 
      </property> 
      <mapping class="com.tushar.hibernate.model.User" /> <!-- This is the line which return an error --> 
      <mapping class="com.tushar.hibernate.model.Sender" /> 
     </bean>

模型类用户：

@Entity 
@Table(name = "user") 
public class User { 

    @Id 
    @GeneratedValue 
    @Column(name = "u_id") 
    private int userId; 

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

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

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

    private Set<Sender> userSenderId = new HashSet<Sender>(0); 

    public int getUserId() { 
     return userId; 
    } 

    public void setUserId(int userId) { 
     this.userId = userId; 
    } 

    public String getName() { 
     return name; 
    } 

    public void setName(String name) { 
     this.name = name; 
    } 

    public String getMobile() { 
     return mobile; 
    } 

    public void setMobile(String mobile) { 
     this.mobile = mobile; 
    } 

    public String getEmail() { 
     return email; 
    } 

    public void setEmail(String email) { 
     this.email = email; 
    } 

    @OneToMany(cascade = CascadeType.ALL) 
    @JoinTable(name = "user_sender", joinColumns = { @JoinColumn(name = "u_id") }, inverseJoinColumns = { @JoinColumn(name = "s_id") }) 
    public Set<Sender> getUserSenderId() { 
     return userSenderId; 
    } 

    public void setUserSenderId(Set<Sender> userSenderId) { 
     this.userSenderId = userSenderId; 
    } 

}

模型类发件人：

@Entity 
@Table(name = "sender") 
public class Sender { 

    @Id 
    @GeneratedValue 
    @Column(name = "s_id") 
    private int sId; 

    @Column(name = "sender_id") 
    private String senderId; 

    @ManyToOne(cascade=CascadeType.ALL) 
    private User user; 

    public int getsId() { 
     return sId; 
    } 

    public void setsId(int sId) { 
     this.sId = sId; 
    } 

    public String getSenderId() { 
     return senderId; 
    } 

    public void setSenderId(String senderId) { 
     this.senderId = senderId; 
    } 

    public User getUser() { 
     return user; 
    } 

    public void setUser(User user) { 
     this.user = user; 
    } 
}

这是两个类，我想相互映射 @OneToMany用户发送人和@ManyToOne发件人给用户

但经营项目后，返回像一些错误：当我试图做模型映射没有dispatcher-servlet.xml文件写入映射属性

You have already declared the model classes in the xml: 

<list> 
     <value>com.tushar.hibernate.model.User</value> 
     <value>com.tushar.hibernate.model.Sender</value> 
</list> 

You don't need to add the mapping entries, and also this configuration is used by spring and mapping tag in not allowed here. If you are using hibernate.cfg.xml file then you can declare your mappings there(Only if you are not using annotations). 

You just need to add @Entity annotation on top of your model classes.

嗨Ravi，我已经在模型类中使用@Entity但无法进行映射。 –

<mapping class="com.tushar.hibernate.model.User" />

这个标签是不存在<bean>标签..

如果你有Hibernate的配置文件，然后使用下面的标签来配置春季CFG的SessionFactory的bean，它的CFG文件文件 -

<property name="configLocation" value="hibernate_cfg_file_name"/>

如果你删除<mapping>标签，那么你的程序可以工作....

试试吧......

Hi Navnath，我删除了标记和错误也从dispatcher-servlet.xml中消失了，但是在运行该项目之后，它返回了我上面提到的一些错误。 –

@TusharKharat以上错误可能是由于MySQL 5.1.X使用mysql 5.1.35连接器jar –

没有解决使用mysql 5.1.35连接器jar的问题。同样的错误来了 –
