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

  1. 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>

     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 }
    View Code
  3. 配置xwork.xml(位于classes下)
    技术分享
    <!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
  4. 新建view:hello.jsp 
    技术分享
    <%@ 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>
    View Code

     

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