(ssh)一个简单的struts，hibernate例子以及struts,hibernate集成

最近在学几个常用框架的集成，下面是一个关于struts+hibernate的集成的例子，大家都知道，任何一个复杂的东西，都是从简单开始的，所以我先说一个struts+hibernate集成，然后再进一步了解，希望对这方面爱好的能有所帮助
一、新建一个项目（如ssh）
二、加入该项目对struts的支持，就是相关struts包，（右击你新建的项目－>MyEclipse，选add struts.........）
三、添加了对struts支持后，然后在struts-config.xml文件里右击，新建－>form action and jsp选项，那样就可以把这三个文件新建好 register1.jsp,Register1Action.java,Register1Form.java（你可以把这三个文件发布到tomcat进行测试），测试成功就可以执行下一步
四、新建一个表sstest表，有字段id,username,password,id为主健和自动增1
五，同样的方法添加对hibernate支持
六、对新建的数据表进行hibernate进行映射,打开myhibernate视图，右击你sstest表->选hibernate revers engineering选项，然后把Sstest.hbm.xml文件映射到hibernateDao包中，同时选中工具 hibernate mapping file..., java data object....., java data access object dao...选项，先中这几个文件就可以产生下列几个.java文件:BaseHibernateDAO. ,HibernateSessionFactory ,IBaseHibernateDAO, Sstest,SstestDAO,最后你对你的代码进行测试，测试成功，进行下一步
七、好了，关于struts和hibernate代码基本上差不好了，下面来看一直代码，代码为蓝色的就是集成的地方,主要是看Register1Action代码,其它的代码都是自动生成的
相关代码如下：
register1.jsp

<%@ page language="java" pageEncoding="ISO-8859-1"%>
<%@ taglib uri="http://struts.apache.org/tags-bean" prefix="bean"%>
<%@ taglib uri="http://struts.apache.org/tags-html" prefix="html"%>
<html>
<head>
  <title>JSP for Register1Form form</title>
</head>
<body>
  <html:form action="/register1">
   password : <html:password property="password"/><html:errors property="password"/><br/>
   username : <html:text property="username"/><html:errors property="username"/><br/>
   <html:submit/><html:cancel/>
  </html:form>
</body>
</html>

Register1Action.java

package com.yourcompany.struts.action;

import hibernateDao.Sstest;
import hibernateDao.SstestDAO;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.hibernate.Transaction;

import com.yourcompany.struts.form.Register1Form;

public class Register1Action extends Action {
//数据dao
SstestDAO sd;
public Register1Action() {
  // TODO Auto-generated constructor stub
  setSd(new SstestDAO());
}
public ActionForward execute(ActionMapping mapping, ActionForm form,
   HttpServletRequest request, HttpServletResponse response) {
  Register1Form register1Form = (Register1Form) form;// TODO Auto-generated method stub
  //输出客户端的用户名
  response.setCharacterEncoding("GB2312");
  System.out.println("register1Form.name\t"+register1Form.getUsername());
  /*
   * 数据库操作
   * */
  Sstest st = new Sstest();
  st.setUsername(register1Form.getUsername());
  st.setPassword(register1Form.getPassword());
  //dao对象
  SstestDAO sd = getSd();
  Transaction tran = sd.getSession().beginTransaction(); //开始事务
  sd.save(st);
  tran.commit();
  //请求转发到success
  return mapping.findForward("success");
}
//数据dao，get，set方法
public void setSd(SstestDAO sd) {
  this.sd = sd;
}
public SstestDAO getSd() {
  return sd;
}
}

Register1Form.java
package com.yourcompany.struts.form;

import javax.servlet.http.HttpServletRequest;
import org.apache.struts.action.ActionErrors;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionMapping;

public ActionErrors validate(ActionMapping mapping,
   HttpServletRequest request) {
  // TODO Auto-generated method stub
  return null;
}

public void reset(ActionMapping mapping, HttpServletRequest request) {
// TODO Auto-generated method stub
this.username = "qin";
}

public String getPassword() {
return password;
}

public void setPassword(String password) {
this.password = password;
}

public String getUsername() {
return username;
}

public void setUsername(String username) {
this.username = username;
}
}
如果你觉得你的代码自动生成有问题的话，你可以参考下列代码

BaseHibernateDAO.java

package hibernateDao;

import org.hibernate.Session;

public class BaseHibernateDAO implements IBaseHibernateDAO {

public Session getSession() {
return HibernateSessionFactory.getSession();
}
}

private static final ThreadLocal<Session> threadLocal = new ThreadLocal<Session>();
    private static Configuration configuration = new Configuration();
    private static org.hibernate.SessionFactory sessionFactory;
    private static String configFile = CONFIG_FILE_LOCATION;

static {
    try {
   configuration.configure(configFile);
   sessionFactory = configuration.buildSessionFactory();
  } catch (Exception e) {
   System.err
     .println("%%%% Error Creating SessionFactory %%%%");
   e.printStackTrace();
  }
    }
    private HibernateSessionFactory() {
    }
    public static Session getSession() throws HibernateException {
        Session session = (Session) threadLocal.get();

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

        return session;
    }
public static void rebuildSessionFactory() {
  try {
   configuration.configure(configFile);
   sessionFactory = configuration.buildSessionFactory();
  } catch (Exception e) {
   System.err
     .println("%%%% Error Creating SessionFactory %%%%");
   e.printStackTrace();
  }
}
    public static void closeSession() throws HibernateException {
        Session session = (Session) threadLocal.get();
        threadLocal.set(null);

        if (session != null) {
            session.close();
        }
    }

public static org.hibernate.SessionFactory getSessionFactory() {

}

恩！对我来说是好东西。开始学SSH，学的一头雾水。

呵呵！挺简单的！

这个我看视频教程学过一点，但对SSH还是没有入门。心情挺烦的！

也要谢谢博主发这个贴子。
