hibernate

有关HbernateSessionFactory中得到getCurrentSession()方法还是得到getSession()方法,myeclipse中，好像是可以自动获取的，但是不记得要怎么配置去了

myeclipse中要怎么配置才能自动生成getCurrentSession()方法

是直接右键添加的hibernate，但是生成的不是getCurrentSession()方法而是getSession()方法,

[code="java"] public static Session getCurrentSession() throws HibernateException {
Session session = (Session) threadLocal.get();

    if (session == null || !session.isOpen()) {
        if (sessionFactory == null) {
            rebuildSessionFactory();
        }
        session = (sessionFactory != null) ? sessionFactory.getCurrentSession()
                : null;
        threadLocal.set(session);
    }

    return session;
}[/code]

[code="java"]package com.pai.charge;

import org.hibernate.HibernateException;
import org.hibernate.Session;
import org.hibernate.cfg.Configuration;

/**

• Configures and provides access to Hibernate sessions, tied to the
• current thread of execution. Follows the Thread Local Session

• pattern, see {@link http://hibernate.org/42.html }.
  */
  public class HibernateSessionFactory {

  /**

  • Location of hibernate.cfg.xml file.
  • Location should be on the classpath as Hibernate uses
    
  • #resourceAsStream style lookup for its configuration file.

  static {
  try {
  configuration.configure(configFile);
  sessionFactory = configuration.buildSessionFactory();
  } catch (Exception e) {
  System.err
  .println("%%%% Error Creating SessionFactory %%%%");
  e.printStackTrace();
  }
  }
  private HibernateSessionFactory() {
  }

是这个吗

当你加入hibernate 框架的时间就会自己生成了.

项目 右键 -> myeclipse -> add hibernate ... .有一下 HibernateSessionFactory 的配置,加到相关的包下就可以了

你手工加一下不就是了吗
