Struts2.3.15.3+hibernate-core-4.2.7+Spring3.2.5整合
提示：所需要的jar包，很多不过不需要记忆，所有类库放在一起就行了，谁要我发给他。921353419@qq.com
jar 包拷入webRoot根目录下的lib目录下
柿子还是软的捏，因为hibernate和Spring都不依赖与Web容器所以很轻松就可以整合
1.在源码包下，也就是Src目录下新建名称为applicationContext.xml为文件如下图所示
2.在新建的applicationContext.xml中书写相关配置如下：

3.在web项目中引入Struts2并将其与Spring结合
在web.xml中添加Struts2、Spring的拦截器并增加一些常用的基础过滤器
<?xml version="1.0" encoding="UTF-8"?>
<web-app 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"
version="3.0">
<!-- Welcome File List -->
<welcome-file-list>
<welcome-file>/jsplib/index.jsp</welcome-file>
</welcome-file-list>
<!-- WebApp Root -->
<context-param>
<param-name>webAppRootKey</param-name>
<param-value>webapp.root</param-value>
</context-param>
<!-- Spring OpenSessionInView -->
<filter>
<filter-name>openSessionInView</filter-name>
<filter-class>org.springframework.orm.hibernate4.support.OpenSessionInViewFilter</filter-class>
<init-param>
<param-name>flushMode</param-name>
<param-value>AUTO</param-value>
</init-param>
<init-param>
<param-name>singleSession</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>openSessionInView</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!-- Spring Encoding Filter -->
<filter>
<filter-name>encodingFilter</filter-name>
<filter-class>
org.springframework.web.filter.CharacterEncodingFilter

<init-param>

<param-value>UTF-8</param-value>
</init-param>
</filter>
<!-- Spring Encoding Filter Mapping -->
<filter-mapping>
<filter-name>encodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!-- Struts2 Filter -->
<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>
<!-- Struts2 Filter Mapping -->
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!-- Log4j ConfigurationFile Location -->
<context-param>

<param-value>classpath:log4j.properties</param-value>
</context-param>
<!-- Spring Log4j Listener -->

</listener-class>
</listener>
<!-- Spring ConfigurationFile Location -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<!-- Spring Context Listener -->
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>
<!-- Spring Web Request Listener -->
<listener>
<listener-class>
org.springframework.web.context.request.RequestContextListener
</listener-class>
</listener>
<!-- Spring Introspector Cleanup Listener -->
<listener>
<listener-class>
org.springframework.web.util.IntrospectorCleanupListener
</listener-class>
</listener>
</web-app>
4.在WebRoot下新建 struts.xml 配置Struts2的相关参数
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
"http://struts.apache.org/dtds/struts-2.3.dtd">
<struts>
<constant name="struts.devMode" value="true" />
<constant name="struts.i18n.encoding" value="UTF-8" />
<!-- 指定由spring负责action对象的创建 -->
<constant name="struts.objectFactory" value="spring" />
<!-- 是否启用开发模式 -->
<constant name="struts.devMode" value="false" />
<!-- struts配置文件改动后，是否重新加载 -->
<constant name="struts.configuration.xml.reload" value="true" />
<!-- 设置浏览器是否缓存静态内容 -->
<constant name="struts.serve.static.browserCache" value="true" />
<!-- 请求参数的编码方式 -->
<constant name="struts.i18n.encoding" value="utf-8" />
<!-- 每次HTTP请求系统都重新加载资源文件，有助于开发 -->
<constant name="struts.i18n.reload" value="false" />
<!-- 文件上传最大值 -->
<constant name="struts.multipart.maxSize" value="104857600" />
<!-- 让struts2支持动态方法调用 -->
<constant name="struts.enable.DynamicMethodInvocation" value="true" />
<!-- Action名称中是否可使用斜线 -->
<constant name="struts.enable.SlashesInActionNames" value="false" />
<!-- 允许标签中使用表达式语法 -->
<constant name="struts.tag.altSyntax" value="true" />
<!-- 对于WebLogic,Orion,OC4J此属性应该设置成true -->
<constant name="struts.dispatcher.parametersWorkaround" value="false" />
<!-- 设置Convention插件是否从jar包中搜索Action类 [可选] 默认值为true -->
<constant name="struts.convention.action.disableJarScanning" value="true" />
<!-- 设置Convention插件文件协议类型 -->
<constant name="struts.convention.action.fileProtocols" value="jar,wsjar" />
<!-- 设置Convention插件需要搜索的jar包 -->
<constant name="struts.convention.action.includeJars" value=".*?/sshe*.*?jar(!/)?" />
<package name="default" namespace="/" extends="struts-default">
<action name="*_*">
<result>/jsplib/{1}/{2}.jsp</result>
</action>
</package>
</struts>
此时Spring3+hibernate4+Struts2已经紧紧的结合在一起了。
spring就像一个讨人喜欢的孩子，左手攥着Hibernate右手拉着Struts2
