一、基本概念
Struts：作为基于 MVC 模式的 Web 应用最经典框架，两个项目Struts 和webwork已经集成，成为现在的Struts2。目前的最新版本是2.0.9（2007-7）。
Spring：是一个轻型的容器，利用它可以使用一个外部 XML 配置文件方便地将对象连接在一起。每个对象都可以通过显示一个 JavaBean 属性收到一个到依赖对象的引用，留给您的简单任务就只是在一个XML 配置文件中把它们连接好。
Hibernate 是一个纯 Java 的对象关系映射和持久性框架，它允许您用 XML 配置文件把普通 Java 对象映射到关系数据库表。使用 Hibernate 能够节约大量项目开发时间，因为整个 JDBC 层都由这个框架管理。这意味着您的应用程序的数据访问层位于 Hibernate 之上，完全是从底层数据模型中抽象出来的。
三种技术到目前已经比较成熟，而且他们都是免费的！让我们对三者集成进行一个初览（简单而不专业）：
我们用Struts实现从Web（网页，MVC中的View）到后台系统的映射（WebàAction），然后由Spring管理这些Action，把它们作为Bean和其他对象一起处理。这些Bean之间处理业务逻辑、数据、系统状态等，且它们被Spring统一管理，为了区分，就算大概包括MVC的MC部分吧。然后需要持久化的数据由Spring和Hibernate之间的接口交由Hibernate处理（这个属于持久层）。
必须基础：只要Java基础，一点HTML知识、XML基础就可以了。本文的目的就是从零开始建立第一个Struts+Spring+Hibernate应用。即使它是最简单的，我们也希望初学者能够从中理解一些思想，其中也包括系统架构的设计思想。
配置 pom.xml 依赖

在web.xml中配置spring与struts的相关代码
<filter>
<filter-name>struts2filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilterfilter-class>
filter>
<filter-mapping>
<filter-name>struts2filter-name>
<url-pattern>/*url-pattern>
filter-mapping>
2）配置spring的监听器
当服务启动时，就会先加载spring的配置文件
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListenerlistener-class>
listener>
3）配置默认加载路径
<context-param>
<param-name>contextConfigLocationparam-name>
<param-value>classpath:applicationContext.xmlparam-value>
context-param>
src下编写相关配置文件
1)spring:applicationContext.xml
导入相关约束
xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd

http://www.springframework.org/schema/aop/spring-aop.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx.xsd">
beans>
2）hibernate:hibernate.cfg.xml
导入相关约束，并配置数据库
xml version='1.0' encoding='utf-8'?>
DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<property name="hibernate.connection.driver_class">com.mysql.cj.jdbc.Driverproperty>
<property name="connection.url">jdbc:mysql://localhost:3306/customerproperty>
<property name="connection.username">jiangproperty>

<property name="connection.provider_class">org.hibernate.connection.C3P0ConnectionProviderproperty>
<mapping resource="domain/Product.hbm.xml"/>
session-factory>
hibernate-configuration>
3）配置log4j.properties
### direct log messages to stdout ###
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.err
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n
### direct messages to file mylog.log ###
log4j.appender.file=org.apache.log4j.FileAppender
log4j.appender.file.File=c\:mylog.log
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n
### set log levels - for more verbose logging change 'info' to 'debug' ###
log4j.rootLogger=info, stdout
4)struts2:struts.xml
导入相关约束
