spring与struts1集成方案(一)

该方案并未将struts交与spring管理，仅仅是将struts单独植入。

web.xml

<?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"version="2.5"xsi:schemaLocation="http://java.sun.com/xml/ns/javaee   http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"><!--指定spring配置文件位置,默认从web根目录寻找配置文件。另外可以根据spring提供的classpath:前缀来指定从类路径下查找 --><context-param><param-name>contextConfigLocation</param-name><param-value>classpath*:spring/*.xml</param-value></context-param><!-- 初始化spring容器(通过监听)：ContextLoader是一个工具类，用来初始化WebApplicationContext，其主要方法就是initWebApplicationContext，主要的工作是把WebApplicationContext(XmlWebApplicationContext是默认实现类)放在了ServletContext中;ServletContext也是一个"容器"，也是一个类似Map的结构.而WebApplicationContext在ServletContext中的KEY就是WebApplicationContext.ROOT_WEB_APPLICATION_CONTEXT_ATTRIBUTE.我们如果要使用WebApplicationContext则需要从ServletContext取出，Spring提供了一个WebApplicationContextUtils类，可以方便的取出WebApplicationContext，只要把ServletContext传入就可以了。--><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><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><welcome-file-list><welcome-file>index.jsp</welcome-file></welcome-file-list></web-app>

spring配置文件、service层未改动，参见spring与hibernate集成.

action

package com.ch.action;import java.util.List;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.apache.struts.action.ActionForm;import org.apache.struts.action.ActionForward;import org.apache.struts.action.ActionMapping;import org.apache.struts.actions.DispatchAction;import org.springframework.web.context.WebApplicationContext;import org.springframework.web.context.support.WebApplicationContextUtils;import org.springframework.web.context.support.XmlWebApplicationContext;import com.ch.dao.IPersonService;import com.ch.entity.Person;public class PersonAction extends DispatchAction {@Overrideprotected ActionForward unspecified(ActionMapping mapping, ActionForm form,HttpServletRequest request, HttpServletResponse response)throws Exception {// TODO Auto-generated method stubreturn list(mapping, form, request, response);}@SuppressWarnings("unchecked")public ActionForward list(ActionMapping mapping, ActionForm form,HttpServletRequest request, HttpServletResponse response)throws Exception {// TODO Auto-generated method stub/** * 在web应用中，spring容器在启动的时候就被初始化(参见web.xml)。 * 所以我们可以通过spring的工具类WebApplicationContextUtils来获取上下文 */WebApplicationContext wc = WebApplicationContextUtils.getWebApplicationContext(request.getSession().getServletContext());IPersonService personService2 = (IPersonService) wc.getBean("personService");List<?> list = (List<Person>) personService2.findAllPersons();request.setAttribute("list", list);return mapping.findForward("list");}}

struts-config.xml
