整合的准备工作

第二步、web.xml里面配置struts2拦截器和配置Spring的ioc容器

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" 
	xmlns="http://java.sun.com/xml/ns/javaee" 
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
	http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
  <display-name></display-name>	
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
  <!-- 把Spring资源文件配置 -->
 <!-- 配置监听器 -->
  <context-param> 
  <!-- 上下文配置路径 --> 
  <param-name>contextConfigLocation</param-name> 
  <!-- 访问spring配置信息 --> 
  <param-value>classpath:applicationContext.xml</param-value>
   </context-param> 
   <!-- 配置spring启动listener入口 --> 
   <listener> 
   <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> 
   </listener>

  <servlet>
    <servlet-name>GoodsServlet</servlet-name>
    <servlet-class>cn.com.servlet.GoodsServlet</servlet-class>
  </servlet>

  <servlet-mapping>
    <servlet-name>GoodsServlet</servlet-name>
    <url-pattern>/GoodsServlet</url-pattern>
  </servlet-mapping>
  <!--拦截器设置  -->
    <filter>
        <filter-name>struts2</filter-name>
        <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
    </filter>

    <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
</web-app>

---

第三步、db.properties

jdbc.username=root
jdbc.password=123456
jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc\:mysql\:///lifan

第四步、applicationContext.xml文件（HIbernate.cfg.xml文件都集成在这个文件里面了）

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

	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

	<bean class="org.apache.commons.dbcp.BasicDataSource" id="dataSource">
		<property name="username" value="${jdbc.username}"></property>

	<bean id="SessionFactoryBean"

		     	<prop key="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</prop>
			</props>
		</property>
		
		<!-- 添加映射文件 -->

查询数据库里面的数据显示在页面上

实体类

package cn.com.bean;
public class Goods {
//这里是产品的信息
	private int goodnum;
	private String goodaddress;
	private String goodname;
	private double price;
	private int account;
	public int getGoodnum() {
		return goodnum;
	}
	public void setGoodnum(int goodnum) {
		this.goodnum = goodnum;
	}
	public String getGoodaddress() {
		return goodaddress;
	}
	public void setGoodaddress(String goodaddress) {
		this.goodaddress = goodaddress;
	}
	public String getGoodname() {
		return goodname;
	}
	public void setGoodname(String goodname) {
		this.goodname = goodname;
	}
	public double getPrice() {
		return price;
	}
	public void setPrice(double price) {
		this.price = price;
	}
	public int getAccount() {
		return account;
	}
	public void setAccount(int account) {
		this.account = account;
	}
	
}

映射文件

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd" >
<hibernate-mapping>
<class name="cn.com.bean.Goods" table="goods" catalog="lifan">
<id column="goodnum" name="goodnum">
<generator class="native"></generator>
</id>
<property name="goodaddress" column="goodaddress" type="string"></property>
<property name="goodname" column="goodname" type="string"></property>
<property name="price" column="price" type="double"></property>
<property name="account" column="account" type="int"></property>
</class>
</hibernate-mapping>

查询信息的接口和实现类(HIbernate操作数据库+Spring注解和事务、AOP)

package cn.com.inter;

import java.util.List;

import cn.com.bean.Goods;

public interface GoodsService {
//1.查询Goods的所有信息
	public List<Goods> getGoodsList();
}

package cn.com.dao;
import java.util.List;
import java.util.Map;

import org.apache.struts2.interceptor.RequestAware;
import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;
import org.springframework.transaction.annotation.Transactional;
import com.opensymphony.xwork2.ModelDriven;
import com.opensymphony.xwork2.Preparable;
import cn.com.bean.Goods;
import cn.com.inter.GoodsService;
@Repository(value="goodsServiced")
public class GoodsServiceImpl implements GoodsService,RequestAware{
	// 1.使用Hibernate操作数据库
	// 1.1使用当前线程绑定的session
	@Autowired
	private SessionFactory sessionfactory;

	private Session getSession() {
		return sessionfactory.getCurrentSession();
	}

	// 测试没有问题
	@Transactional
	public List<Goods> getGoodsList() {
		System.out.println("common in....");
		// 1.连接数据库
		String sql = "from Goods";
		Query query = getSession().createQuery(sql);
		List<Goods> lists = query.list();

		return lists;
	}

	@Override
	public void setRequest(Map<String, Object> arg0) {
	
	}


	

}

Servlet

package cn.com.servlet;
import java.io.IOException;
import java.util.List;
import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.context.WebApplicationContext;
import org.springframework.web.context.support.WebApplicationContextUtils;
import com.opensymphony.xwork2.ModelDriven;
import com.opensymphony.xwork2.Preparable;
import cn.com.bean.Goods;
import cn.com.inter.GoodsService;
public class GoodsServlet extends HttpServlet  {
	public void doGet(HttpServletRequest request, HttpServletResponse response)
			throws ServletException, IOException {
		doPost(request, response);
	}
	public void doPost(HttpServletRequest request, HttpServletResponse response)
			throws ServletException, IOException {
		// 1.获取上下文
			ServletContext sc = getServletContext();
		WebApplicationContext ac = WebApplicationContextUtils
				.getRequiredWebApplicationContext(sc);
		GoodsService gh = (GoodsService) ac.getBean("goodsServiced");
		// 调用方法
		System.out.println("gh"+gh);
		List<Goods> lists=gh.getGoodsList();
     request.setAttribute("list", lists);
	request.getRequestDispatcher("/goodslist.jsp").forward(request, response);
	}
	
}

显示页面（s标签）

<%@ 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>铜陵力凡自动化-产品列表</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">
</head>
<body>
	<!-- 头部 -->
	<jsp:include page="headcommon.jsp"></jsp:include>
<table>
<tr><td>产品</td><td>说明</td><td>价格</td><td>销量</td></tr>
<s:iterator value="#request.list">
<tr><td><img src=${goodaddress } /></td>
<td>${goodname}</td>
<td>${price}</td>
<td>${account}</td>
</tr>
</s:iterator>
</table>
</body>
</html>

---

这里对Struts只是用到了在页面上显示s标签；后面更多的灵活使用
