Question

我刚开始用jsf学习hibernate，这是我自己创建的示例应用程序。我得到的课程没有发现异常（即POJO课程）以下是我的代码，请帮我编码。

HibernateBean是我的POJO类

package com.bectran.employee;

public class HibernateBean {

    private int id;
    private String userName;
    private String passwd;

    public HibernateBean() {

        // TODO Auto-generated constructor stub
    }

    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }

    public String getPasswd() {
        return passwd;
    }

    public void setPasswd(String passwd) {
        this.passwd = passwd;
    }

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }


}

连接类

package com.bectran.employee;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry;
import org.hibernate.service.ServiceRegistryBuilder;

public class LoginMain {

    public LoginMain() {
        // TODO Auto-generated constructor stub
    }
    public static void save1(){
        Configuration cfg = new Configuration();
        cfg.configure("hibernate.cfg.xml"); 
        ServiceRegistryBuilder registry = new ServiceRegistryBuilder();
        registry.applySettings(cfg.getProperties());
        ServiceRegistry serviceRegistry = registry.buildServiceRegistry();
        SessionFactory sessionFactory = cfg.buildSessionFactory(serviceRegistry);
        Session session = sessionFactory.openSession();
        HibernateBean hb=new HibernateBean();
        Transaction tx = session.beginTransaction();
        session.save(hb);
        System.out.println("Object saved successfully.....!!");
        tx.commit();
        session.close();
        sessionFactory.close();
    }
}
