Emp.java

public class Emp 

{
    private int id;
    private String name,cmpname;


    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 String getCmpname() {
        return cmpname;
    }
    public void setCmpname(String cmpname) {
        this.cmpname = cmpname;
    }

}

public class Test {

    public static void main(String[] args) {

    Emp e = new Emp();
    e.setId(1);
    e.setName("harsh");
    e.setCmpname("vardhan");

    try 
    {
    SessionFactory factory = new Configuration().configure("hibernate.cfg.xml").buildSessionFactory();
    Session sess=factory.openSession();
    sess.beginTransaction();
    sess.save(e);
    sess.getTransaction().commit();

    }
    catch (HibernateException exception) 
    {
        exception.printStackTrace();

Answer 1

使用了错误的属性class而不是resource来包含映射文件。应该：

<mapping resource="emp.hbm.xml"/>
