SSH 框架为 Struts + Spring + Hibernate。

　　集成SSH框架的系统从职责上分为四层：数据持久层和域模块层，以帮助开发人员在短期内搭建结构清晰、可复用性好、维护方便的Web应用程序。其中使用Struts作为系统的整体基础架构，负责MVC的分离，在Struts框架的模型部分，控制业务跳转，利用Hibernate框架对持久层提供支持，Spring做管理，管理struts和hibernate。具体做法是：用面向对象的分析方法根据需求提出一些模型，将这些模型实现为基本的Java对象，然后编写基本的DAO(Data Access Objects)接口，并给出Hibernate的DAO实现，采用Hibernate架构实现的DAO类来实现Java类与数据库之间的转换和访问，最后由Spring做管理，管理struts和hibernate。

一、Struts

　　1）本质：过滤器（就像一条看门狗，一旦有请求访问就要经过它）

　　2）功能：对用户发送的请求，按照不同的业务要求，跳转到不同的页面，把部分信息作为参数传递

二、Spring

1）本质：监听器（就像一只鸟，盘旋在空中，监视着程序运行，在程序运行过程中负责注入实例）　　　　　

　　2）功能：管理所用到的实现类。

三、Hibernate

　　1）本质：服务器和数据库交互的媒介

　　2）功能：负责对数据库的一些操作（如：建表、增、删、查、改等）

大概结构，根据个人习惯

一，配置applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>

	</bean> 

</beans>

二，struts

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>
	<constant name="struts.enable.DynamicMethodInvocation" value="true" />
	<constant name="struts.custom.i18n.resources" value="message" />
	<constant name="struts.i18n.encoding" value="UTF-8" />
	<constant name="struts.ui.theme" value="simple" />
	<package name="renthouse" extends="struts-default">
		<default-action-ref name="defaultAction" />
		<action name="defaultAction" class="cn.action.Default">
			<result name="fail">/page/fail.jsp</result>
		</action>

		<action name="list" class="GoodsAction" method="list">
			<result name="success">/page/show.jsp</result>
		</action>


		<action name="updatelist" class="updateAction" method="list">
			<result name="success">/page/update.jsp</result>
		</action>
		<action name="update" class="updateAction" method="update">
			<!-- 进行重定向 -->
			<result name="success" type="redirectAction">list</result>
			<!-- 失败继续留在修改页面 -->
			<result name="input">/page/update.jsp</result>
		</action>
	</package>
</struts>

三，show.jsp

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%@ taglib prefix="s" uri="/struts-tags"%>
<%
	String path = request.getContextPath();
	String basePath = request.getScheme() + "://"
			+ request.getServerName() + ":" + request.getServerPort()
			+ path + "/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">

<title>My JSP 'select.jsp' starting page</title>



</head>

<body>
	<s:form>
		<table border="1" align="center">
			<tr>
				<td>商品编号</td>
				<td>商品名称</td>
				<td>商品价格</td>
				<td>库存数量</td>
				<td>订单状态</td>
				<td>操作</td>
			</tr>
			<!-- cn.action.GoodsAction中的list() != null -->
			<s:if test="list!=null">
				<s:iterator value="list">
					<tr>
						<td><s:property value="id" />
						</td>
						<td><s:property value="goods_name" />
						</td>
						<td><s:property value="goods_price" />
						</td>
						<td><s:property value="goods_count" />
						</td>
						<td><s:property value="bill_status" />
						</td>
						<td>
							<a href="updatelist.action?id=<s:property value="id" />">修改</a>
						</td>
					</tr>
				</s:iterator>
			</s:if>
		</table>
	</s:form>


</body>
</html>

四 update.jsp

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%@ taglib prefix="s" uri="/struts-tags"%>
<%
	String path = request.getContextPath();
	String basePath = request.getScheme() + "://"
			+ request.getServerName() + ":" + request.getServerPort()
			+ path + "/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">

<title>My JSP 'update.jsp' starting page</title>

</head>

<body>
	<s:form action="update.action">
		<s:iterator value="list">
			<table border="1" align="center">
				<tr>
					<td>商品编号</td>
					<td><s:textfield name="id" readonly="true" />
					</td>
				</tr>
				<tr>
					<td>商品名称</td>
					<td><s:textfield name="goods_name" />
					</td>
				</tr>
				<tr>
					<td>商品价格</td>
					<td><s:textfield name="goods_price" />
					</td>
				</tr>
				<tr>
					<td>库存数量</td>
					<td><s:textfield name="goods_count" />
					</td>
				</tr>
				<tr>
					<td>订单状态</td>
					<td><s:select name="bill_status"
							list="#{0:'待处理',1:'处理中',2:'已处理'}" headerKey="bill_status" />
					</td>
				</tr>
				<tr>

					<td colspan="2" align="center"><s:submit value="提交" /> <input
						type="button" value="返回" οnclick="window.history.go(-1)" />
					</td>
				</tr>
			</table>
		</s:iterator>
	</s:form>
</body>
</html>

五，index页面

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%@ taglib prefix="s" uri="/struts-tags"%>
<%
	String path = request.getContextPath();
	String basePath = request.getScheme() + "://"
			+ request.getServerName() + ":" + request.getServerPort()
			+ path + "/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">

<title>My JSP 'index.jsp' starting page</title>
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="This is my page">
<!--
	<link rel="stylesheet" type="text/css" href="styles.css">
	-->
</head>

<body>
	<center>
		<s:form action="list.action">
    	请选择区域：<select class="text" name="goods_district">
    			<option value="0">请选择</option>
				<option value="1">朝阳区订单</option>
				<option value="2">海淀区订单</option>
				<option value="3">丰台区订单</option>
				<option value="4">西城区订单</option>
				<option value="5">昌平区订单</option>
			</select>
			<s:submit value="查询" />
		</s:form>

	</center>
</body>
</html>

实体类和*.hbm.xml根据逆向生成吧

具体自己百度

只是总结简单的环境搭建

写的不是很好，自己根据自己个人情况随便总结的

不喜勿喷
