ZhbBean类

package zhb.ssh.entity;

import java.io.Serializable;

public class ZhbBean implements Serializable {

private int id;
private String name;
private int typeId;

public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getTypeId() {
return typeId;
}
public void setTypeId(int typeId) {
this.typeId = typeId;
}

}

执行的Java类：
package zhb.ssh.dao;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;

import zhb.ssh.entity.ZhbBean;

public class ZhbDao {

  public ZhbBean getZhb(int id){
  SessionFactory sf=new Configuration().configure().buildSessionFactory();
Session session=sf.openSession();
ZhbBean zb=(ZhbBean)session.get(ZhbBean.class, id);
sf.close();
return zb;
}
  public static void main(String[] args){
ZhbDao z=new ZhbDao();
ZhbBean zhb= z.getZhb(2);
System.out.println(zhb.getName());
  }
}

2、org.hibernate.MappingException: invalid mapping

3、org.xml.sax.SAXParseException: Document root element "hibernate-mapping", must match DOCTYPE root "Hibernate-mapping".
