strutshibernate:一个简单的struts hibernate例子以及struts hibernate集成

来源: 发布时间:星期四, 2009年1月15日 浏览:14次 评论:0
　　最近在学几个常用框架集成下面是个有关struts+hibernate集成例子大家都知道任何个复杂东西都是从简单开始所以我先说个struts+hibernate集成然后再进步了解希望对这方面爱好能有所帮助

　　、新建个项目(如ssh)

　　 2、加入该项目对struts支持就是相关struts包(右击你新建项目－>MyEclipse选add struts.........)

　　 3、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 3个文件新建好 register1.jsp,Register1Action.java,Register1Form.java(你可以把这 3个文件发布到tomcat进行测试)测试成功就可以执行下步

　　 4、新建个表sstest表有字段id,username,password,id为主健和自动增1

　　 5同样思路方法添加对hibernate支持

　　 6、对新建数据表进行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,最后你对你代码进行测试测试成功进行下步

　　 7、好了有关struts和hibernate代码基本上差不好了下面来看直代码代码为蓝色就是集成地方,主要是看Register1Action代码,其它代码都是自动生成

　　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 Register1Action extends Action {
//数据dao
SstestDAO sd;
public Register1Action {
　// TODO Auto-generated constructor stub
　Sd( SstestDAO);
}
public ActionForward execute(ActionMapping mapping, ActionForm form,
　 HttpServletRequest request, HttpServletResponse response) {
　Register1Form register1Form = (Register1Form) form;// TODO Auto-generated method stub
　//输出客户端用户名
　response.CharacterEncoding("GB2312");
　.out.prln("register1Form.namet"+register1Form.getUsername);
　/*
　 * 数据库操作
　 * */
　Sstest st = Sstest;
　st.Username(register1Form.getUsername);
　st.Password(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
　 mapping.findForward("success");
}
//数据daoget思路方法
public void Sd(SstestDAO sd) {
　this.sd = sd;
}
public SstestDAO getSd {
　 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
　 null;
}
public void re(ActionMapping mapping, HttpServletRequest request) {
　// TODO Auto-generated method stub
　this.username = "qin";
}
public String getPassword {
　 password;
}
public void Password(String password) {
　this.password = password;
}
public String getUsername {
　 username;
}
public void Username(String username) {
　this.username = username;
}
}如果你觉得你代码自动生成有问题话你可以参考下列代码

　　BaseHibernateDAO.java

private final ThreadLocal<Session> threadLocal = ThreadLocal<Session>;
　　private　 Configuration configuration = Configuration;
　　private org.hibernate.SessionFactory sessionFactory;
　　private String configFile = CONFIG_FILE_LOCATION;
{
　　 try {
　 configuration.configure(configFile);
　 sessionFactory = configuration.buildSessionFactory;
　} catch (Exception e) {
　 .err
　　 .prln("%%%% Error Creating SessionFactory %%%%");
　 e.prStackTrace;
　}
　　}
　　private HibernateSessionFactory {
　　}
　　public Session getSession throws HibernateException {
　　　　Session session = (Session) threadLocal.get;
　 (session null || !session.isOpen) {
　 (sessionFactory null) {
　　rebuildSessionFactory;
　 }
　 session = (sessionFactory != null) ? sessionFactory.openSession
　　 : null;
　 threadLocal.(session);
　}
　　　　 session;
　　}
public void rebuildSessionFactory {
　try {
　 configuration.configure(configFile);
　 sessionFactory = configuration.buildSessionFactory;
　} catch (Exception e) {
　 .err
　　 .prln("%%%% Error Creating SessionFactory %%%%");
　 e.prStackTrace;
　}
}
　　public void closeSession throws HibernateException {
　　　　Session session = (Session) threadLocal.get;
　　　　threadLocal.(null);
　　　　 (session != null) {
　　　　　　session.close;
　　　　}
　　}
public org.hibernate.SessionFactory getSessionFactory {
