1.hibernate.cfg.xml如下

<?xml version='1.0' encoding='utf-8'?>

2.Student.hbm.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC

3.Student.java

package cn.hibernate5.basic;

public class Student {
	private int id;
	private String name;
	private String sex;
	
	public Student(){
		
	}

	public int getId() {
		return id;
	}

	public String getSex() {
		return sex;
	}

	public void setSex(String sex) {

	}

4.Hibernate.java (此类用于获取SessionFactory)

package Test;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.boot.MetadataSources;
import org.hibernate.boot.registry.StandardServiceRegistry;
import org.hibernate.boot.registry.StandardServiceRegistryBuilder;

import cn.hibernate5.basic.Student;

public class Hibernate {

	protected static SessionFactory getSessionFactory() throws Exception {
		SessionFactory sessionFactory = null;
		// A SessionFactory is set up once for an application!
		final StandardServiceRegistry registry = new StandardServiceRegistryBuilder()
				.configure() // configures settings from hibernate.cfg.xml
				.build();
		try {
			sessionFactory = new MetadataSources(registry).buildMetadata()
					.buildSessionFactory();
		} catch (Exception e) {
			// The registry would be destroyed by the SessionFactory, but we had
			// trouble building the SessionFactory
			// so destroy it manually.
			StandardServiceRegistryBuilder.destroy(registry);
		}

		return sessionFactory;
	}
}

5.StudentTest.java(测试类)

package Test;

import org.hibernate.Session;
import org.hibernate.SessionFactory;

import cn.hibernate5.basic.Student;

public class StudentTest {
	public static void main(String args[]) {
		SessionFactory sf = null;
		try {
			sf = Hibernate.getSessionFactory();
		} catch (Exception e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}

		Student s = new Student();
		s.setId(1);
		s.setName("fangshusen");
		s.setSex("man");

		Session session = sf.getCurrentSession();
		session.beginTransaction();
		session.save(s);
		session.getTransaction().commit();
		session.close();
	}

}

运行测试时的一场信息

hbm.xml里面的id 没有生成策略吗？ 你发一下控制台的信息看一下

Project -> Source -> Clean-up清一下项目试试，也可能是缺少jar包commons-lang-1.0-b1.jar
