本文主要是介绍Struts2 formBean传值，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
1.首先创建一个web项目
2.给该web项目添加Struts2依赖
3.最后项目结构如下:(action、model这些包自己添加)
关键的web.xml,struts.xml如下:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0"><display-name>StrutsTest</display-name><!--struts2的核心分发器--><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><!--欢迎页面--><welcome-file-list><welcome-file>index.html</welcome-file><welcome-file>index.htm</welcome-file><welcome-file>index.jsp</welcome-file><welcome-file>default.html</welcome-file><welcome-file>default.htm</welcome-file><welcome-file>default.jsp</welcome-file></welcome-file-list>
</web-app>struts.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">
<struts><!-- 指定全局资源 --><constant name="struts.custom.i18n.resources" value="mess"></constant><!-- 指定编码 --><constant name="struts.custom.i18n.encoding" value="utf-8"></constant>
</struts>
3.创建mess.properties(消息属性配置文件)
loginPage=\u767B\u9646\u9875\u9762
erroPage=\u5931\u8D25\u9875\u9762
succPage=\u6210\u529F\u9875\u9762
user=\u7528\u6237\u540D
pass=\u5BC6\u7801
login=\u767B\u9646
5.创建登陆页面(index.jsp)
<%@ page language="java" import="java.util.*" pageEncoding="utf-8" isELIgnored="false"%>
<!--引入struts标签-->
<%@ taglib uri="/struts-tags" prefix="s" %>
<%
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><!--通过mess.properties中的属性值匹配映射--><s:text name="loginPage"></s:text></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">--></head><body><h3>登录页面</h3><!--通过form表传递值--><s:form action="/login"><s:textfield name="per.userName" key="user"></s:textfield><s:textfield name="per.passWord" key="pass"></s:textfield><s:submit key="login"></s:submit></s:form></body>
</html>
6.在strus.xml中配置请求(login.action)的处理类及返回页面映射
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">
<struts><!-- 指定全局资源 --><constant name="struts.custom.i18n.resources" value="mess"></constant><!-- 指定编码 --><constant name="struts.custom.i18n.encoding" value="utf-8"></constant><!--注意一定要配置namespace--><package name="log" extends="struts-default" namespace="/"><action name="login" class="com.action.LoginAction"><!--结果返回页面映射--><result name="success">/page/success.jsp</result><result name="fail">/page/fail.jsp</result></action></package>
</struts>
7.成功页面(success.jsp)和失败页面(fail.jsp)
success.jsp
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%@ taglib uri="/struts-tags" prefix="s" %>
<%
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 'success.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">--></head><body>欢迎:<s:text name="succPage"></s:text></body>
</html>
fail.jsp
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%@ taglib uri="/struts-tags" prefix="s" %>
<%
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 'fail.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">--></head><body>Soory:<s:text name="erroPage"></s:text></body>
</html>
8.发布该应用到tomcat,通过localhost:8080/StrutsTest进行访问
