一、需要的JAR文件为：Spring和Struts2框架本身需要的JAR文件以及他们所依赖的JAR文件，比如commons-logging.jar等等，另外还需要Struts2发布包中的struts2-spring-plugin-x.xx.jar。 二、整合过程:
ch20
1-1--src---1- 各action
1 1 -struts.xml
1
1--webRoot----1-各jsp页面
1----web-Inf----1--applicationContext.xml
1--web.xml
(1)在web.xml中增加WebApplicationContext的相应配置，即listener用来自动加载spring配置文件的位置。还需配置filter 用于struts2
默认spring会加载的web-inf下的applicationContext.xml。
代码：<?xml version="1.0" encoding="UTF-8"?> <web-app version="2.5" 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_2_5.xsd"> <!--定义核心Filter FilterDispatcher --> <filter> <!-- 定义核心Filter的名称 --> <filter-name>struts2</filter-name> <!--定义核心Filter的实现类 --> <filter-class> org.apache.struts2.dispatcher.FilterDispatcher </filter-class> </filter> <filter-mapping> <!--核心Filter的名称 --> <filter-name>struts2</filter-name> <!--使用该核心Filter来接受所有的Web请求 --> <url-pattern>/*</url-pattern> </filter-mapping> <!-- 初始化Spring容器 --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> </web-app> 配置spring的配置文件的位置 Servlet 2.3及以上版本可以使用监听器，相应配置如下： <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/classes/applicationContext.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener>
2.建立提交页jsp 如以form形式
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <%@taglib uri="/struts-tags" prefix="s" %> <!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>login</title> </head> <body> <center> <s:form action="login"> <s:textfield name="uname" label="姓名："></s:textfield> <s:textfield name="upass" label="密码："></s:textfield> <s:submit value="登录"/> </s:form> </center> </body> </html>
3.建立对应的action其中的属性为form中的那几个。可以再写一个其他类，用于判定的条件。此处是Logincheck
package com.web.action; import com.opensymphony.xwork2.ActionContext; import com.opensymphony.xwork2.ActionSupport; import com.web.service.LoginCheck; public class LoginAction extends ActionSupport { private static final long serialVersionUID = 1L; private String uname; private String upass; private LoginCheck lc; private String mess="input"; public String getUname() { return uname; } public void setUname(String uname) { this.uname = uname; } public String getUpass() { return upass; } public void setUpass(String upass) { this.upass = upass; } public LoginCheck getLc() { return lc; } public void setLc(LoginCheck lc) { this.lc = lc; } public String execute()throws Exception{ if(lc.check(this.getUname(), this.getUpass())) { mess="success"; ActionContext.getContext().getSession().put("uname", uname); } return mess; } }
4.上面的loginaction
package com.web.service; public class LoginCheck { public boolean check(String uname,String upass) { if(uname.equals("zhang")&&upass.equals("zhang")) { return true; } else return false; } }
5.只要是类，就需要在applicationContext.xml中进行配置，通过他来维护他们之间的关系
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd"> <!-- 创建业务逻辑组件实例 --> <bean id="loginCheck" class="com.web.service.LoginCheck"></bean> <!-- 创建控制器实例 --> <bean id="loginAction" class="com.web.action.LoginAction"> <property name="lc" ref="loginCheck"></property> </bean> </beans>
6.配置struts.xml
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" "http://struts.apache.org/dtds/struts-2.0.dtd"> <struts> <package name="struts" extends="struts-default"> <action name="login" class="loginAction"> <result name="success">/loginSuccess.jsp</result> <result name="input">/loginfail.jsp</result> </action> </package> </struts>
7.最终将跳转的结果页建出来即可。
