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

        -->
        <global-results>
            <result name="error">/WEB-INF/jsp/fail.jsp</result>

        <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+"/";
%>

        $("#form1").submit();
    });
});
</script>
  </head>

  <body>
