Myeclipse下开发一个简单的struts和hibernate整合的例子

JSP专栏 2008-10-21 08:41:47 阅读591 评论0 字号：大中小

一.实验目的:

自己摸索了好久,才学会.为了让更多的人也能容易的作出一个struts和hibernate整合的例子,特把过程写下来,以便哥们们学习.(spring下次再整合)

二.实验环境:

(1)mysql5.0

　　(2)eclipse 3.2

　　(3)myeclipse5.0

　　(4)tomcat-5.0.28

说明:下载和安装的的事,我就不说了.看看我BLOG里其他文章或者到网上去搜索.

环境变量都要设置好.一切都准备好了,下面开始.

三.实验过程:

(1)建立工程

在myeclipse里新建一个工程。在左边的Package Exporler面版里点右键选择new->project ,在跳出菜单里选择MyEclipse->J2EE Projects->Web Project,点下面的Next.跳出对话框

取个工程名:liupro.然后点Fish.

(2)建立数据库

我用了MySQL主据库的图形化界面管理工具---Navicat(这不是必须的,你想用甚么都可以,也可以完全手动输入),避免了DOS风格的输入.

先连线:按上面填写,其中密码是你MySQL的密码

之后,就和SQL SERVER一样了,先建立一个数据库,名字:liupro;建立一个表,名字: admin;字段: id,name,password其中id为自动取值的主键(自增1,别忘记设置我画图时已经忘了).如下图:

(3).配置MyEclipse Databases Exporler

再回到myeclipse ，选中window->Open Perspective->Other…

可以看到现在跳出一个名为Select Perspective的菜单，在里面选中MyEclipse Databases Exporler，确定之后.如果第一次,打开它,那它就不会跳出下面的页面,直接去左面NEW一个,然后在编辑

之后,去JDBC for MySQL上面右键,OPEN CONNECTION

之后顺序打开,找到了如下:

(4)给工程添加Struts框架

现在我们再回到window->Open Perspective- >Other…里的MyEclipse

或者点击右边的切换按钮回到MyEclipse J2EE DEVELOPMENT

右键点击你刚建立的工程liupro,并选择MyEclipse->Add struts Capabilities…在跳出的对话框里按照如下输入(基本都是默认)并确定：

OK!

(5)给工程添加Hibernate框架

在liupro下面的src右键新建一个包,名字com.hibernate

右键点击你刚建立的工程liupro,并选择MyEclipse-> Add Hibernate Capabilities在跳出的对话框里按照如下输入(基本都是默认),注意需要选者的有:

然后点击Next

然后Finish

(6)连接池(不要怕这个名字,其实就是选一个而已)

我参考的例子上,为了更好的演示我们不建立通常的登陆页面而是建立个注册页面.那我也这样建立一个注册页面.

选择 src目录下的hibernate.cfg.xml文件。照如下填写并保存。这样hibernate就为你建立了数据库的连接池。其实,不用选,右边也默认打开了.如下图:

(7)配置struts-config.xml文件

下面我们再选择liupro/WebRoot/WEB-INF/struts-config.xml文件，在右边出于design模式下,点击右键选择new- >Form, Action and JSP。如下填写

其中切换到JSP选项卡,在 [] Creat JSP form?,记得打上钩,

点击FINISH.

在刚才struts- config.xml文件里右键选择addAdmin选择Properties

在选项卡里选择Forwords，再点add，如下图填写

Finsih.

最后你的struts-config.xml就是下面这个样子：

(8) Create Hibernate Mapping

象第三步一样,记得要用左下角的切换按钮,切换到DB Browser状态,然后在JDBC for MySQL上右键Open Connection,找到liupro/TABLE/admin,在这个表名上右键,选择Hibernate Reverse Engineering,如图

在跳出的对话框里,注意我选择了包名为刚才建立的com.hibernate,然后next;下一页里,ID Generator选择native ;然后Next,选中表之后,可以FINISH了.左边工程文件里会多了一个Admin.java和Hibernate.bhm.xml.

(9) 建立AdminDAOFactory.java文件

我建立在src /com.hibernate下,类名: AdminDAOFactory

全部内容如下:

package com.hibernate;

import org.hibernate.HibernateException;

import org.hibernate.Session;

import org.hibernate.Transaction;

public class AdminDAOFactory {

Session session;

Transaction tx;

public void add(Admin admin) throws HibernateException {

try {

session = HibernateSessionFactory.currentSession();

tx = session.beginTransaction();

//Add a new admin

session.save(admin);

tx.commit ();

}catch(HibernateException e){

//throw e;

System.out.println(e.getMessage());

}finally{

if (tx!=null) {

tx.rollback();

}

HibernateSessionFactory.closeSession();

}

(10)写ACTION

再打开com.yourcompany.struts.action下的

AddAdminAction.java

全部如下:

* Generated by MyEclipse Struts

* Template path: templates/java/JavaClass.vtl

package com.yourcompany.struts.action;

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 com.hibernate.Admin;

import com.hibernate.AdminDAOFactory;

import com.yourcompany.struts.form.AddAdminForm;

/**

* MyEclipse Struts

* Creation date: 04-11-2007

* XDoclet definition:

* @struts.action path="/addAdmin" input="/form/addAdmin.jsp" scope="request" validate="true"

public class AddAdminAction extends Action {

* Generated Methods

/**

* Method execute

* @param mapping

* @param form

* @param request

* @param response

* @return ActionForward

public ActionForward execute(ActionMapping mapping, ActionForm form,

HttpServletRequest request, HttpServletResponse response) {

AddAdminForm addAdminForm = (AddAdminForm) form;

// TODO here

Admin admin = new Admin();

admin.setName(addAdminForm.getName());

admin.setPassword(addAdminForm.getPassword());

AdminDAOFactory adminDAO=new AdminDAOFactory();

adminDAO.add(admin);

return mapping.findForward("success");

}

(11)修改FORM

再打开com.yourcompanyname.struts.form下的AddAdminForm.java

全部文字如下:

/**

* MyEclipse Struts

* Creation date: 04-11-2007

* XDoclet definition:

* @struts.form

public class AddAdminForm extends ActionForm {

* Generated fields

/** password property */

private String password;

/** name property */

private String name;

* Generated Methods

/**

* Method validate

* @param mapping

* @param request

* @return ActionErrors

public ActionErrors validate(ActionMapping mapping,

HttpServletRequest request) {

// TODO Auto-generated method stub

ActionErrors errors=new ActionErrors();

Session session=HibernateSessionFactory.currentSession();

Transaction tx=session.beginTransaction();

Query query = session.createQuery("select admin from Admin as admin where admin.name = '" + this.name + "'");

Iterator it=query.iterate();

if (it.hasNext())

{

errors.add("addAdmin.err.name",new ActionMessage("form.addAdmin.err.name"));

}

tx.commit();

HibernateSessionFactory.closeSession();

return errors;

}

/**

* Method reset

* @param mapping

* @param request

public void reset(ActionMapping mapping, HttpServletRequest request) {

// TODO Auto-generated method stub

}

/**

* Returns the password.

* @return String

public String getPassword() {

return password;

}

/**

* Set the password.

* @param password The password to set

public void setPassword(String password) {

this.password = password;

}

/**

* Returns the name.

* @return String

public String getName() {

return name;

}

/**

* Set the name.

* @param name The name to set

public void setName(String name) {

this.name = name;

}

(12)资源文件里添加出错信息

　再打开com/yourcompany/struts下的ApplicationResource.properties在这里面添加错误信息(就下面一行,没有分号)：

Form.addAdmin.err.name=err

(13)修改JSP页面: 打开webRoot/form下的addAdmin.jsp我的全部文字如下:

<%@ page contentType="text/html; charset=utf-8"%>

<%@ page language="java"%>

<%@ taglib uri="http://jakarta.apache.org/struts/tags-bean" prefix="bean"%>

<%@ taglib uri="http://jakarta.apache.org/struts/tags-html" prefix="html"%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html:html>

<head>

<html:base />

<title>login.jsp</title>

</head>

<body>

<html:form action="/addAdmin" focus="name" method="GET">

<td colspan="2" >新增管理员</td>

</tr>

<tr>

</tr>

<tr>

</tr>

<tr>

</tr>

</html:form>

</table>

</center>

</body>

</html:html>

Success.jsp页面信息全部如下:

<%@ page contentType="text/html; charset=utf-8"%>

<%@ page language="java"%>

<%@ taglib uri="http://jakarta.apache.org/struts/tags-bean" prefix="bean" %>

<%@ taglib uri="http://jakarta.apache.org/struts/tags-html" prefix="html" %>

<%@ taglib uri="http://jakarta.apache.org/struts/tags-logic" prefix="logic" %>

<%@ taglib uri="http://jakarta.apache.org/struts/tags-tiles" prefix="tiles" %>

<%@ taglib uri="http://jakarta.apache.org/struts/tags-template" prefix="template" %>

<%@ taglib uri="http://jakarta.apache.org/struts/tags-nested" prefix="nested" %>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html:html locale="true">

<head>

<html:base />

<title>success.jsp</title>

<!--

-->

</head>

<body>

管理员用户已经存入数据库! <br>

成功了!</body>

</html:html>

(13)测试

现在打开浏览器，输入　http://127.0.0.1:8080/liupro/addAdmin.jsp如果没有错误,就可以看到你的jsp页面了！

也可以在MYECLIPSE里面直接点那个小地球的图标,更方便一些.输入地址就可以测试了.
