如何在Spring MVC和Hibernate中使用多个数据库？

例如，我有一个类映射到第一个数据库中的表，第二个类映射到第二个数据库中的表。我想在一个应用程序中同时使用它们。我在调度员servlet.xml中如何在Spring MVC和Hibernate中使用多个数据库？

<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.hibernate3.annotation.AnnotationSessionFactoryBean"> 
     <property name="dataSource" ref="dataSource" /> 
     <property name="annotatedClasses"> 
      <list> 
       <value>com.example.model.Article</value> 
      </list> 
     </property> 
     <property name="hibernateProperties"> 
      <props> 
       <prop key="hibernate.dialect">${hibernate.dialect}</prop> 
       <prop key="hibernate.show_sql">${hibernate.show_sql}</prop>    
      </props> 
     </property> 
    </bean>

定义数据源的bean，这里是我的映射类

import java.util.Date; 

import javax.persistence.Column; 
import javax.persistence.Entity; 
import javax.persistence.GeneratedValue; 
import javax.persistence.Id; 
import javax.persistence.Table; 

@Entity 
@Table(name = "article") 
public class Article { 

    @Id 
    @GeneratedValue 
    @Column(name = "article_id") 
    private Long articleId; 

    @Column(name = "article_name", nullable = false, length=20) 
    private String articleName; 

    @Column(name = "article_desc", nullable = false) 
    private String articleDesc; 

    @Column(name = "date_added") 
    private Date addedDate; 

    public Article() {  
    } 

    public Long getArticleId() { 
     return articleId; 
    } 

    public void setArticleId(Long articleId) { 
     this.articleId = articleId; 
    } 

    public String getArticleName() { 
     return articleName; 
    } 

    public void setArticleName(String articleName) { 
     this.articleName = articleName; 
    } 

    public String getArticleDesc() { 
     return articleDesc; 
    } 

    public void setArticleDesc(String articleDesc) { 
     this.articleDesc = articleDesc; 
    } 

    public Date getAddedDate() { 
     return addedDate; 
    } 

    public void setAddedDate(Date addedDate) { 
     this.addedDate = addedDate; 
    } 
}

我该如何映射这个类的第一个数据库和第二类的第二？非常感谢您的回复！

您将不得不定义两个数据源和两个会话工厂。一个会话工厂拥有一个数据源的引用。
