注意：struts2.5 之后最低需要 jdk7，myeclipse8.6 只支持 jdk1.6，因此只能用 struts2.3

开始第一个 Struts2.3 的 Hello World

  1. 配置 MyEclipse 的 jdk，注意 jdk 选择 jdk1.6

    位置：

    Windows -> preferences -> Java -> Installed JREs

    ​

  2. 打开 myeclipse8.6，新建一个 Web project

    ​

  3. 复制 struts2.3 需要的 jar 包到 WEB-INF/lib 目录

    jar 包分别是：

    commons-fileupload-1.4.jar
commons-io-2.2.jar
commons-lang3-3.2.jar
freemarker-2.3.28.jar
javassist-3.11.0.GA.jar
ognl-3.0.21.jar
struts2-core-2.3.37.jar
xwork-core-2.3.37.jar

    ​

  4. 配置 web.xml，添加 struts2 的过滤器

    <?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">

	<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>

</web-app>

  5. 在 src 目录添加 Action 处理逻辑

    package space.terwer.struts2;

public class LoginAction {
	private String username;
	private String password;

	public String getUsername() {
		return username;
	}

	public void setUsername(String username) {
		this.username = username;
	}

	public String getPassword() {
		return password;
	}

	public void setPassword(String password) {
		this.password = password;
	}

	public String execute(){
		return "success";
	}
}

  6. 在 src 目录新建 struts.xml，配置 struts.xml，加上登录流程

    <?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>

	<package name="struts2" extends="struts-default">
		<action name="login" class="space.terwer.struts2.LoginAction">
			<result name="success">/result.jsp</result>
		</action>
	</package>

</struts>

  7. 新建登录页面 login.jsp，加上表单提交逻辑

    <%@ 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 'login.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>
		<form action="login">
			用户名：
			<input type="text" name="username" />
			<br />
			密码：
			<input type="password" name="password" />
			<br />

			<input type="submit" value="提交" />

		</form>
	</body>
</html>

  8. 添加结果页面 result.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 'reault.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>
		用户名：${requestScope.username}
		<br />
		密码：${requestScope.password }
	</body>
</html>

  9. 部署到 tomcat

    添加tomcat到MyEclipse

    Windows -> Preferences -> MyEclispe -> Tomcat -> Tomcat 6.x

    ​

    部署到tomcat

    可以直接修改 tomcat 的 conf/server.xml，在 Host 节点加上部署代码：

    <Context path="/struts2" docBase="C:\Users\terwer\Documents\MyEclipse86Workspace\struts2\WebRoot" reloadable="true" />

  10. 启动 tomcat
