属性“列”/“类型”必须为元素类型“属性”声明

Question

我是一名新手休眠配置。在我的Eclipse项目中，我得到了上面的休眠错误。

在PERSONDB类中，有五列命名为PERSON_ID，PERSON_FIRSTNAME，PERSON_LASTNAME，PERSON_GENDER，PERSON_AGE。

Person.java：

package com.hibernate.data; 

public class Person { 
private int id; 
private String firstName; 
private String lastName; 
private String gender; 
private int age; 

public int getId() { 
    return id; 
} 
public void setId(int id) { 
    this.id = id; 
} 
public String getFirstName() { 
    return firstName; 
} 
public void setFirstName(String firstName) { 
    this.firstName = firstName; 
} 
public String getLastName() { 
    return lastName;

public void setGender(String gender) { 
    this.gender = gender; 
} 
public int getAge() { 
    return age; 
} 
public void setAge(int age) { 
    this.age = age; 
} 
} 

我该如何解决这个问题？

我改变

<?xml version="1.0" encoding="utf-8"?> 
<!DOCTYPE hibernate-mapping 
PUBLIC "-//Hibernate/Hibernate Mapping DTD//EN" 
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd"> 

到

<?xml version="1.0"?> 
<!DOCTYPE hibernate-mapping PUBLIC 
    "-//Hibernate/Hibernate Mapping DTD 3.0//EN" 
     "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> 

现在，它的工作原理。
