SSH2框架搭建示例

SSH2

本文只是入门搭建，要想深入可自行摸索。

首先我们建立一个工程，所需jar包如下：SSH2所需jar打包下载

jar包注意不要重复了。

下面开始配置：

• web.xml

• structs.xml

• action

package com.wanghaifeng.MySystem.action;import java.util.List;import org.hibernate.Session;import org.hibernate.SessionFactory;import org.hibernate.cfg.Configuration;import com.opensymphony.xwork2.ActionSupport;import com.wanghaifeng.MySystem.entity.User;public class UserAction extends ActionSupport{public String getUser() {return "success";}private static SessionFactory factory;public String errUser() {String hqlString = " from User"; Configuration cfg=new Configuration().configure();           //建立SessionFactory           factory=cfg.buildSessionFactory();    //获取Session  Session session=factory.openSession();  List<User> query = session.createQuery(hqlString).list();  User  user = (User)query.get(0);  System.out.println("年龄："+user.getAge()+"姓名："+user.getUserName()+"号码："+user.getUserId());return "error";}}

输出

Hibernate: select user0_.USERNAME as USERNAME0_, user0_.AGE as AGE0_, user0_.PASSWORD as PASSWORD0_, user0_.USERID as USERID0_ from T_USER user0_
