2. 在web.xml中注册Struts2.3.8核心控制器
<?xml version="1.0" encoding="UTF-8"?> <web-app version="3.0" 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_3_0.xsd"> <display-name>Struts2.3.8</display-name> <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> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> </web-app>
3. 建立视图文件
chapter02/part01/input.jsp
<%@ 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>Chapter02 | Part01</title>
</head>
<body>
<form id="helloForm" action="hello.action" method="post">
<table>
<tr>
<td>Your Name:</td>
<td><input type="text" name="username"></td>
</tr>
<tr>
<td> </td>
<td><input type="submit" value="Submit"></td>
</tr>
</table>
</form>
</body>
</html>
chapter02/part01/view.jsp
<%@ 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>Chapter02 | Part01</title>
</head>
<body>
Hello! ${requestScope.username}! Welcome to Struts2.3.8 ...
</body>
</html>
4. 建立处理请求的Action
package chapter02.part01.action;
public class HelloAction {
private String username;
public String execute() throws Exception {
System.out.println("Hello! " + username + "! Welcome to Struts2.3.8 ...");
return "success";
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
}
5. 在struts.xml中注册Struts2.3.8的Action
<?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="chapter02.part01" extends="struts-default">
<action name="hello" class="chapter02.part01.action.HelloAction">
<result>view.jsp</result>
</action>
</package>
</struts>
6. 查看项目目录结构
7. 发布运行
