spring整合struts
整合目标:使用spring的bean管理struts action service。
整合步骤:
一、加入spring
1、加入spring jar包
2、配置web.xml文件
<context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener>
3、加入spring配置文件
二、加入struts2
1、加入struts2 jar包
2、在web.xml配置
<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>
2、加入struts2 对spring支持的插件包struts2-spring-plugin-2.3.31.jar
3、加入struts2配置文件
4、创建一个简单service和action
package com.hy.service; public class PersonService { public void save() { System.out.println("personService save..."); } }
package com.hy.action; import com.hy.service.PersonService; public class PersonAction { private PersonService personService; public PersonService getPersonService() { return personService; } public void setPersonService(PersonService personService) { this.personService = personService; } public String execute() { System.out.println("execute..."); personService.save(); return "success"; } }
5、在spring的配置文件中配置action和service
<bean name="personService" class="com.hy.service.PersonService"></bean> <bean name="personAction" class="com.hy.action.PersonAction" scope="prototype"> <property name="personService" ref="personService"></property> </bean>
注意action的scope必须是prototype(非单例模式)
6、在struts2配置文件中配置action
<action name="person-save" class="personAction"> <result>/success.jsp</result> </action>
7、创建测试页面
<%@ page language="java" contentType="text/html; charset=utf-8" pageEncoding="utf-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <title>Insert title here</title> </head> <body> <a href="person-save">person-save</a> </body> </html>
