Webwork 学习笔记

1. 首先配置一个简单的webwork应用

核心jar:

commons-logging.jar
ognl.jar
oscore.jar
velocity-dep.jar
webwork-2.1.7.jar
xwork.jar

配置web.xml

<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app>
    <servlet>
        <servlet-name>webwork</servlet-name>
        <servlet-class>com.opensymphony.webwork.dispatcher.ServletDispatcher</servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>webwork</servlet-name>
        <url-pattern>*.action</url-pattern>
    </servlet-mapping>
    <taglib>
        <taglib-uri>webwork</taglib-uri>
        <taglib-location>/WEB-INF/lib/webwork-2.1.7.jar</taglib-location>
    </taglib>
</web-app>

新建action: HelloWorld.java　　

 1 package com.aeolia.action;
 2 
 3 import java.text.SimpleDateFormat;
 4 import java.util.Date;
 5 
 6 import com.opensymphony.util.Data;
 7 import com.opensymphony.xwork.Action;
 8 
 9 public class HelloWorld implements Action {
10     private String message;
11     private String name;
12 
13     public String getName() {
14         return name;
15     }
16 
17     public void setName(String name) {
18         this.name = name;
19     }
20 
21     @Override
22     public String execute() throws Exception {
23         String result = "";
24         if (this.name == null || this.name.equalsIgnoreCase("world") || this.name.equals("")) {
25             result = INPUT;
26             message = "Blank name or names of world are not allowed ";
27         } else {
28             message = "Hello World ! ";
29             java.text.SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd");
30             Date date = new Date();
31             String dateString = format.format(date);
32             message += this.name;
33             message += "  time is " + dateString;
34             result = SUCCESS;
35         }
36         return result;
37     }
38 
39     public String getMessage() {
40         return message;
41     }
42 
43 }

配置xwork.xml（位于classes下）

<!DOCTYPE xwork PUBLIC "-//OpenSymphony Group//XWork 1.0//EN" "http://www.opensymphony.com/xwork/xwork-1.0.dtd">
<xwork>
    <include file="webwork-default.xml" />
    <package name="default" extends="webwork-default">
        <default-interceptor-ref name="completeStack" />
        <action name="HelloWorld" class="com.aeolia.action.HelloWorld">
            <result name="success">hello.jsp</result>
            <result name="input">name.jsp</result>
        </action>
    </package>
</xwork>

View Code

新建view:hello.jsp

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="MS932"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<%@taglib prefix="ww" uri="webwork"%>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
    Show message
    <ww:property value="message" />
</body>
</html>

完成，现在可以访问http://localhost:8080/web/HelloWorld.action
