Hibernate Annotation 的问题!!
我在项目已加载hibernate3.2jar和hibernate_annotation.jar的包和已用jdk1.6,但我在entity类输入(写)@id,@Column时总是报错找不到符号:
package hibernateinfo;

import org.hibernate.annotations.AccessType;
import org.hibernate.annotations.Entity;
import org.hibernate.annotations.Table;
import org.hibernate.mapping.Column;
/**
 *
 * @author jacky
 */
@Entity//这里不显示错误
@AccessType("property")

@Table(name="per")//这里显示错误

public class per implements java.io.Serializable{
   
  private Integer id;
  private String name;
  private String address ;
  private String tel;
  private String passward ;
   
  public per() 
  {
  }
  @id//这里显示错误  
  [color=#FF0000][/color]@Column(name="id")//这里显示错误
  public void setId(Integer _id)
  {
  id = _id ;
  }
   
  public Integer getId()
  {
  return id ;
  }
  @Column(name="name")// 显示错误
  public void setName(String _name)
  {
  name = _name;
  }
   
  public String getName()
  {
  return name ;
  }
  @Column(name="passward")//显示错误
  public void setPassward(String _passward)
  {
  passward =_passward ;
  }
   
  public String getPassward()
  {
  return passward ;
  }
   
  @Column(name = "address")//显示错误
  public void setAddress(String _address)
  {
  address =_address;
  }
   
  public String getAddress()
  {
  return address ;
  }
  @Column(name = "tel")//显示错误
  public void setTel(String _tel)
  {
  tel =_tel;
  }
   
  public String getTel()
  {
  return tel ;
  }

请各位帮帮手,谢谢!!!!!!!!1

在hibernate.cfg.xml注意配置

比如
pre-insert 必须实现org.hibernate.event.PreInsertEventListener
