这个SSH整合的例子，用到了许多经典的整合技巧，能帮助初学者清晰的理解整合的步骤和技巧，我们也可以使用这个框架为模版，来搭建自己SSH的环境。


首先我列出关键的整合步骤


1.建立WEB项目的目录结构

?? a.strtus的 ActionServlet 配置在web.xml 中

?? b.将spring的监听器 配置在web.xml

?? c.字符乱码过滤器 配置在web.xml

<?xml version="1.0" encoding="UTF-8"?><web-app xmlns="http://java.sun.com/xml/ns/j2ee"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.4"xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"><context-param><param-name>contextConfigLocation</param-name><param-value>/WEB-INF/applicationContext.xml</param-value></context-param><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><filter><filter-name>Set Character Encoding</filter-name><filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class><init-param><param-name>encoding</param-name><param-value>UTF-8</param-value></init-param></filter><filter><filter-name>sitemesh</filter-name><filter-class>com.opensymphony.module.sitemesh.filter.PageFilter</filter-class></filter><filter-mapping><filter-name>sitemesh</filter-name><url-pattern>/*</url-pattern></filter-mapping><filter-mapping><filter-name>Set Character Encoding</filter-name><url-pattern>/*</url-pattern></filter-mapping><servlet><servlet-name>action</servlet-name><servlet-class>org.apache.struts.action.ActionServlet</servlet-class><init-param><param-name>config</param-name><param-value>/WEB-INF/struts-config.xml</param-value></init-param><init-param><param-name>debug</param-name><param-value>3</param-value></init-param><init-param><param-name>detail</param-name><param-value>3</param-value></init-param><load-on-startup>0</load-on-startup></servlet><servlet-mapping><servlet-name>action</servlet-name><url-pattern>*.do</url-pattern></servlet-mapping><session-config><session-timeout>120</session-timeout></session-config><!-- The Usual Welcome File List --><welcome-file-list><welcome-file>index.do</welcome-file></welcome-file-list><jsp-config><taglib><taglib-uri>/WEB-INF/struts-bean.tld</taglib-uri><taglib-location>/WEB-INF/struts-bean.tld</taglib-location></taglib><taglib><taglib-uri>/WEB-INF/struts-html.tld</taglib-uri><taglib-location>/WEB-INF/struts-html.tld</taglib-location></taglib><taglib><taglib-uri>/WEB-INF/struts-logic.tld</taglib-uri><taglib-location>/WEB-INF/struts-logic.tld</taglib-location></taglib><taglib><taglib-uri>/WEB-INF/struts-nested.tld</taglib-uri><taglib-location>/WEB-INF/struts-nested.tld</taglib-location></taglib><taglib><taglib-uri>/WEB-INF/struts-template.tld</taglib-uri><taglib-location>/WEB-INF/struts-template.tld</taglib-location></taglib><taglib><taglib-uri>/WEB-INF/struts-tiles.tld</taglib-uri><taglib-location>/WEB-INF/struts-tiles.tld</taglib-location></taglib><taglib><taglib-uri>sitemesh-page</taglib-uri><taglib-location>/WEB-INF/sitemesh-page.tld</taglib-location></taglib><taglib><taglib-uri>sitemesh-decorator</taglib-uri><taglib-location>/WEB-INF/sitemesh-decorator.tld</taglib-location></taglib></jsp-config><welcome-file-list><welcome-file>login.jsp</welcome-file></welcome-file-list></web-app>

2.编写spring的配置文件 applicationContext.xml

?

? a. 配置数据源

? b.让spring来管理SessionFactory

? c.配置事务

? d.配置Hibernate 属性以及映射文件

? e.定义DAO和DAO代理

? f.根据需要配置AOP

? g.定义struts的配置
