一、创建Maven项目
http://www.cnblogs.com/zhanqun/p/8425571.html
二、添加struts2核心依赖包以及其他依赖项
打开pom.xm配置界面
点击Add按钮添加struts2-core.jar
选中并点击Ok添加进入项目即可；添加完成后如下
三、新建Action
1、新建package名为cn.smallbyte.mavendemo.action
2、在包内创建以UserAction命名的class，继承自com.opensymphony.xwork2.ActionSupport
UserAction.java内容如下
package cn.smallbyte.mavendemo.action;
import java.io.UnsupportedEncodingException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts2.ServletActionContext;
import com.opensymphony.xwork2.ActionSupport;
public class UserAction extends ActionSupport {
private static final long serialVersionUID = 1L;
public String execute() {
return SUCCESS;
}
public String login() {
try {
HttpServletRequest request = ServletActionContext.getRequest();
HttpServletResponse response = ServletActionContext.getResponse();
request.setCharacterEncoding("UTF-8");
response.setContentType("text/html;charset=utf-8");
String username = request.getParameter("username");
String password = request.getParameter("password");
System.out.println("name->" + username + ",password->" + password);
if ("admin".equals(username) && "123456".equals(password)) {
return SUCCESS;
} else {
return "login";
}
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
return SUCCESS;
}
}
3、配置struts2的核心配置文件（src/main/resources下struts.xml文件），内容如下：
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
"http://struts.apache.org/dtds/struts-2.3.dtd">
<struts>
<constant name="struts.enable.DynamicMethodInvocation" value="false" />
<constant name="struts.devMode" value="true" />
<package name="mavendemoAction" namespace="/demo" extends="struts-default">
<action name="login" class="cn.smallbyte.mavendemo.action.UserAction"
method="login">
<result name="success">/success.jsp</result>
<result name="login">/login.jsp</result>
</action>
</package>
</struts>
4、配置/src/main/webapp/WEB-INF/web.xml，内容如下：
<?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>mavendemo</display-name>
<!-- struts2 -->
<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>*.action</url-pattern>
</filter-mapping>
</web-app>
5、创建web页面
struts.xml文件中配置了success.jsp/login.jsp两个页面
login.jsp如下
<%@ 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>Login Page</title>
</head>
<body>
<form action="${pageContext.request.contextPath}/demo/login.action" method="post">
username:<input type="text" name="username" value="" /><br />
password:<input type="text" name="password" value="" /> <br />
<input type="submit" value="提交" />
</form>
</body>
</html>
success.jsp如下
<%@ 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>Login Success</title>
</head>
<body>Login Success
</body>
</html>
6、编译
鼠标右键点击项目，然后依次选择
Run As -> Maven Install直到出现如下Build Success消息表示编译成功
7、发布
鼠标右键项目 -> Run As -> Run On Server -> Manually define a new server ->Tomcat v7.0 Server
点击finish完成。
8、验证
在浏览器输入：http://localhost:8080/mavendemo/demo/login.action
输入admin/123456后提交后登录成功并跳转到success.jsp页面
