刚从官网下了hibernate4.3.4，结果照着官网doc中的示例class，xml写报了两个错误，实在是头疼

实体类：
package cn.edu.jmu.hibernate.model;

public class Student {
private int id;
private String name;
private int age;
public int getAge() {
return age;
}
public int getId() {
return id;
}
public String getName() {
return name;
}
public void setAge(int age) {
this.age = age;
}
public void setId(int id) {
this.id = id;
}
public void setName(String name) {
this.name = name;
}
}
配置文件：hibernate.cfg.xml
<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE hibernate-configuration SYSTEM "http://hibernate.sourceforge.net/hibernate-configuration-3.0dtd" PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN">

配置文件2：Student.hbm.xml
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0dtd">

</hibernate-mapping>
测试类：StudentTest
import org.hibernate.Session;
import org.hibernate.SessionFactory;

import java.util.*;

import cn.edu.jmu.hibernate.model.*;

import org.hibernate.boot.registry.StandardServiceRegistry;
import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry;
import org.hibernate.tutorial.util.HibernateUtil;

public class StudentTest {

public static void main(String[] args) {
Student st = new Student();
st.setId(6);
st.setName("哈哈");
st.setAge(20);

Session session = HibernateUtil.getSessionFactory().getCurrentSession();//报错之一：21行的。。。
session.beginTransaction();

session.save(st);

session.getTransaction().commit();
}
}
自定义类（测试类中要用到）：HibernateUtil
package org.hibernate.tutorial.util;

import org.hibernate.SessionFactory;
import org.hibernate.boot.registry.StandardServiceRegistryBuilder;
import org.hibernate.cfg.Configuration;

public class HibernateUtil {

private static final SessionFactory sessionFactory = buildSessionFactory();

private static SessionFactory buildSessionFactory() {
// Create the SessionFactory from hibernate.cfg.xml
return new Configuration().configure().buildSessionFactory(
new StandardServiceRegistryBuilder().build() );
}

public static SessionFactory getSessionFactory() {
return sessionFactory;
}

}

hibernate配置文件： <mapping resource="cn/edu/jmu/hibernate/model/Student.hbm.xml"/> <mapping class="cn.edu.jmu.hibernate.model.Student"/> 这两条随便去掉一条。

我把mbpping class 去掉还是有报错。@_@

[花谢尊前不敢香]

http://hibernate.sourceforge.net/hibernate-mapping-3.0dtd"这个应该是http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"，0后面有一个点的。

[Funnee]

我加.了还是不行，是不是jar包没有引入对吗？我只引入了required文件夹下的jar包

[花谢尊前不敢香]

官方hibernate.cfg.xml头文件

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

maping头文件

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

以上才是4.3.4官方文件，不知道你那是从哪里来的。

hibernate官方文档

版主有没有hibernate4.3.4的示例helloworld，我实在是找不出问题所在啊

[Funnee]

找到问题所在了，因为少加了这句：configuration.configure("hibernate.cfg.xml");犯了个低级错误，谢谢大家了

[花谢尊前不敢香]

就我上面那个连接就有一个例子，自己根本不去看。
