WebWork框架簡單示例
1 先下載WebWork框架開發包http://www.opensymphony.com/webwork/download.action 我用的是2.2.4的.
2 .在WebWork框架里建立一個WEB工程.你解壓WebWork的開發包以后會發現有兩個jar文件在***級目錄里面,把他們拷貝進你的工程里面.然后你還會看見lib目錄(webwork開發支持的所有jar文件),lib目錄下面有個defult的目錄,把這個目錄里面的jar文件也都拷貝進你的工程,他們是開發webwork最基本的保障.
3 在src下創建兩個文件.
(1)xwork.xml
- <!DOCTYPE xwork PUBLIC
- "-//OpenSymphony Group//XWork 1.1.1//EN"
- "http://www.opensymphony.com/xwork/xwork-1.1.1.dtd">
- <xwork>
- <include file="webwork-default.xml" />
- <package name="webwork" extends="webwork-default">
- <action name="hello" class="helloworld.HelloWorldAction">
- <result name="yes" type="dispatcher">/yes.jsp
- </result>
- </action>
- </package>
- </xwork>
(2)webwork.properties
webwork.i18n.encoding=GBK
### Load custom property files (does not override webwork.properties!)
# added the MockTag to the path of Tags that the TagDirective will search through
webwork.velocity.tag.path = com.opensymphony.webwork.views.velocity.ui, org.displaytag.tags
webwork.ui.templateDir = template
### Load custom default resource bundles
### XSLT Cache
webwork.xslt.nocache = true
3 web.xml
- xml version="1.0" encoding="UTF-8"?>
- <web-app version="2.4"
- xmlns="http://java.sun.com/xml/ns/j2ee"
- xmlns:xsi="http://www.w3.org/2001/XML
- Schema-instance"
- xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
- http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
- <welcome-file-list>
- <welcome-file>index.jspwelcome-file>
- welcome-file-list>
- <servlet>
- <servlet-name>webworkservlet-name>
- <servlet-class>
- com.opensymphony.webwork.dispatcher.ServletDispatcher
- servlet-class>
- servlet>
- <servlet-mapping>
- <servlet-name>webworkservlet-name>
- <url-pattern>*.actionurl-pattern>
- servlet-mapping>
- web-app>
4 在WebWork框架中創建HelloWorldAction類在helloworld包下,填寫代碼如下:
- package helloworld;
- import com.opensymphony.xwork.Action;
- public class HelloWorldAction implements Action {
- private String userName;
- public String getUserName() {
- return userName;
- }
- public void setUserName(String userName) {
- this.userName = userName;
- }
- public String execute() throws Exception {
- // 處理亂碼
- //userName = new String
- (userName.getBytes("iso-8859-1"),"GBK");
- System.out.println(userName);
- return "yes";
- }
- }
5然后在創建下列兩個jsp頁面.
***個頁面:index.jsp
- <%@ page language="java" import="java.util.*"
- pageEncoding="GBK"%>
- <%
- 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 'index.jsp' starting page
- </title>
- <meta http-equiv="pragma" c>
- <meta http-equiv="cache-control" c>
- <meta http-equiv="expires" c>
- <meta http-equiv="keywords" c>
- <meta http-equiv="description" c>
- <!--
- <link rel="stylesheet" type="text/css"
- href="styles.css">
- -->
- </head>
- <body>
- <form action="hello.action" method="post">
- <input type="text" name="userName"/>
- <br>
- <input type="submit"/>
- </form>
- </body>
- </html>
第二個頁面:yes.jsp
- <%@ page language="java" import="java.util.*"
- pageEncoding="GBK"%>
- <%@ taglib prefix = "ww" uri = "/webwork" %>
- <%
- 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 'yes.jsp' starting page</title>
- <meta http-equiv="pragma" c>
- <meta http-equiv="cache-control" c>
- <meta http-equiv="expires" c>
- <meta http-equiv="keywords" c>
- <meta http-equiv="description" c>
- <!--
- <link rel="stylesheet" type="text/css"
- href="styles.css">
- -->
- </head>
- <body>
- yes. <br>
- <ww:property value="%{userName}"/>
- </body>
- </html>
