1. 新建web工程:web_ssm
2. 导入jar包:
struts2相关jar包

3. web.xml

<!-- 配置struts2 -->  <filter>    <filter-name>struts</filter-name>    <filter-class>      org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter    </filter-class>  </filter>  <filter-mapping>    <filter-name>struts</filter-name>    <url-pattern>*.action</url-pattern>  </filter-mapping>

4.java(仅仅给出action)

package com.login.action;import java.util.Map;import org.apache.struts2.interceptor.ApplicationAware;import org.apache.struts2.interceptor.RequestAware;import org.apache.struts2.interceptor.SessionAware;import com.opensymphony.xwork2.ActionSupport;/** * 登陆鉴权Action类 *  * @author fanjm * @version 1.0 * @since 2017年02月02日 */public class LoginAction extends  ActionSupport implements RequestAware,SessionAware, ApplicationAware{    private static final long serialVersionUID = 2408145375650667872L;    /** log */                    /*private static final Logger logger = LoggerFactory            .getLogger(LoginAction.class);*/    private Map<String, Object> request;    private Map<String, Object> session;    private Map<String, Object> application;    private String username;    private String pwd;    public String login(){        String rtn = ERROR;        if("admin".equals(username)&&"admin".equals(pwd)){            rtn = SUCCESS;        }        return rtn;    }    public String getUsername() {        return username;    }    public void setUsername(String username) {        this.username = username;    }    public String getPwd() {        return pwd;    }    public void setPwd(String pwd) {        this.pwd = pwd;    }    public Map<String, Object> getRequest() {        return request;    }    public void setRequest(Map<String, Object> request) {        this.request = request;    }    public Map<String, Object> getSession() {        return session;    }    public void setSession(Map<String, Object> session) {        this.session = session;    }    public Map<String, Object> getApplication() {        return application;    }    public void setApplication(Map<String, Object> application) {        this.application = application;    }}

5.1 struts文件目录结构
这里写图片描述

5.2 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>    <constant name="struts.i18n.encoding" value="GBK"></constant>   <constant name="struts.enable.DynamicMethodInvocation" value="true" />   <constant name="struts.devMode" value="true" />   <include file="struts-config/struts_login.xml" /><!-- Add packages here --></struts>

5.3 struts_login.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="default" namespace="/as" extends="struts-default">        <!--             自定义拦截器栈        <interceptors>            <interceptor-stack name="timertokenstack">                <interceptor-ref name="defaultStack"/>                <interceptor-ref name="timer"/>                <interceptor-ref name="auth"/>            </interceptor-stack>            <interceptor name="auth" class="com.interceptor.AuthInterceptor"></interceptor>        </interceptors>        -->        <global-results>            <result name="error">/WEB-INF/jsp/fail.jsp</result>        </global-results>        <action name="login" class="com.login.action.LoginAction">            <result name="success">/WEB-INF/jsp/success.jsp</result>        </action>    </package></struts>

6. index.jsp

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%><%String path = request.getContextPath();String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";%><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><html>  <head>    <base href="<%=basePath%>">    <title>My JSP 'index.jsp' starting page</title><meta http-equiv="pragma" content="no-cache"><meta http-equiv="cache-control" content="no-cache"><meta http-equiv="expires" content="0">    <meta http-equiv="keywords" content="keyword1,keyword2,keyword3"><meta http-equiv="description" content="This is my page"><!--<link rel="stylesheet" type="text/css" href="styles.css">--><script src="${pageContext.request.contextPath}/js/jquery-1.11.3.min.js"></script><script type="text/javascript">$(function(){    $("#submit").click(function(){        $("#form1").attr("action","<%=basePath%>as/login!login.action");        $("#form1").submit();    });});</script>  </head>  <body>    This is my JSP page. <br>    <div id='max'>        <form id="form1" name="form1">            <input type="text" name="username" />            <input type="password" name="pwd" />            <button id="submit">submit</button>        </form>    </div>  </body></html>

注:<base href="<%=basePath%>">对$("#form1").attr("action","<%=basePath%>as/login!login.action");不起作用。
