三大框架SSH(struts2+spring+hibernate)整合时相关配置文件的模板

最近在学SSH三大框架的整合，在此对他们整合时相关配置文件做一简单的模板总结，方便以后复用！三大框架SSH(struts2+spring+hibernate)整合时相关配置文件的模板

首先是web.xml配置文件，这里面就配置一些简单的监听器、过滤器，包括spring核心配置文件applicationContext.xml的路径：

web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0">
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<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>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>

接着就是spring的配置文件：applicationContext.xml，可能很多人更习惯命名为beans.xml，由于习惯使用注解方式开发，所以这个是基于annotation的配置，相对xml比较简单！由于这里面已经完成了hibernate配置文件的功能，比如配置数据库等等，所以hibernate.cfg.xml就没必要“苟活”了。

applicationContext.xml
