Recently I plan to start learning Webwork, here I want to take this blog to record my learning history, I hope to make an exchange with all the webwork enthusiasts.
Not much nonsense, I will introduce my preparation for this study:
1. Tools and Environment Preparing JDK1.4.2 (% java_home%) Eclipse3.0 (recommended plugin: lomboz, xmlbuddy, tomcatplugin) WebWork2.1 (% webwork_home%) Tomcat5.0.25
2. Learning information Preparing the tutorial of Webwork2.1 (under WebWork2.1 / DOC)
The following is starting.
[First WebWork Program HelloWorld's Construction]
1. . Eclipse with a new Tomcat Project, where I built a project called Z_Webwork Tomcat Project directory structure Z_Webwork follows: Z_Webwork / work Z_Webwork / WEB-INF Z_Webwork / WEB-INF / classes Z_Webwork / WEB-INF / lib Z_Webwork / WEB-INF / SRC
2. Import% webwork_home% / webwork-2.1.jar to z_WebWork / Web-INF / LIB COPY% WebWork_HOME% / lib / core / *. Jar to z_webwork / web-inf / lib
3. Setting the Eclipse environment variable right-click on the project z_WebWork-> Properties-> java build path-> add library-> user library -> new user-defined library: webwork_lib -> add jars% webwork_home% / web-2.1.jar -> Add Jars% WebWork_Home% / lib / core / *. Jar
4. Establishing three basic profiles (1) Web.xml location in Webwork: z_webwork / web-inf / content is as follows:
My WebWork Application Webwork com.opensymphony.webwork.dispatcher.servletdispatcher 1 Webwork *. Action < / url-pattern> Webwork /web-inf/lib/webwork-2.1.jar < / Tagl Man (/web-app> (2 )XWork.xml location: z_webwork / web-inf / src / content is as follows:
(3) Validators.xml location: z_webwork / web-inf / src / content is as follows:
< validator name = "expression" class = "com.opensymphony.xwork.validator.validators.ExpressionValidator" />
Ok, such a webwork's skeleton is well, the overall structure is as follows:
5. Here we will be in accordance Lesson 3: Actions and Results do an example ex01-index.jsp: This page is a form submitted to an action (HelloWebWorldAction) processing HelloWebWorldAction.java: inherited ActionSupport realized HelloWebWorldAction, here HelloWebWorldAction play in MVC Control ex01 -success.jsp: HelloWorldAction After successful, you will return this page here, in order to facilitate management, I am using the tutorial to build directory LESSON03 / EXAMPLE01 in Z_WebWork, and puts EX01-INDEX.JSP and EX01-SUCCESS.JSP below it The HelloWebWorldAction.java location is Z_WebWork / Web-INF / SRC / Lesson03, in the subsequent notes, all of the examples I will store the code in this structure, respectively, respectively:
//ex01-index.jsp
Webwork tutorial - Lesson 3 - Example 1 </ Title> </ head></p>
<p><body></p>
<p><p> Click The Button Below To Activate HelloWorldAction. </ P></p>
<p><form action = "hellowebworld.action" method = "post"> <p> <input type = "submit" value = "Hello!" /> </ p> </ form></p>
<p></ body> </ html></p>
<p>//HellowebWorldAction.java</p>
<p>Package lesson03;</p>
<p>/ ** * @Author Tailborn * * / import com.opensymphony.xwork.Actionsupport;</p>
<p>Public class hellowebWorldAction Extends ActionSupport {String Hello;</p>
<p>Public string getHello () {return hello;}</p>
<p>Public String Execute () throws exception {hello = "hello, webworld!"; Return Success;}}</p>
<p>//ex01-success.jsp</p>
<p><% @ Taglib Uri = "Webwork" prefix = "ww"%> <html> <head> <title> Webwork tutorial - Lesson 3 - Example 1 </ title> </ head> <body></p>
<p><ww: protoyal value = "hello" /></p>
<p></ body> </ html></p>
<p>6. Configure xwork.xml in <package name = "default" extends = "Webwork-default"></p>
<p>And </ package></p>
<p>The following codes are added to: <! - default-interceptor stack. -> <default-interceptor-ref name = "defaultstack" /> <! - action: Lesson 03: HelloWebWorldAction. -> <action name = HelloWorld "class =" lesson03.hellowebworldAction "> <resultment name =" success "type =" dispatcher "> eX01-success.jsp </ result> </ action> The modified xwork.xml is as follows: <? XML Version =" 1.0 "Encoding =" ISO-8859-1 "> <! Doctype xwork public" - // OpenSymphony Group // xw 1.0 // en "http://www.opensymphony.com/xwork/xwork-1.0.dtd "></p>
<p><xWork> <! - "" "" "" "" "" "" "" "" "" "" "" "" "" "" "- = "Default" extends = "Webwork-default"> <! - default interceptor stack. -> <default-interceptor-ref name = "defaultstack" /> <! - action: Lesson 03: HelloWebWorldAction. -> <action name = "hellowebworld" class = "lesson03.hellowebWorldAction"> <result name = "success" type = "dispatcher"> eX01-success.jsp </ result> </ action> </ package> </ xwork></p>
<p>7. At this point, the first WebWork example is built, start Tomcat, enter: http: // localhost: 8080 / z_webwork / lessost: 8080 / z_WebWork / Lesson03 / Example01 / EX01-index.jsp We will see as shown:</p>
<p>Click the "Hello" button to appear page:</p>
<p>[Example analysis]</p>
<p>This is the first webwork program I made. I heard that Webwork was a simple and elegant MVC mode for the implementation framework than Struts, which didn't come.</p>
<p>Configuration is simple: In the first example, the code that actually needs us only has part of the Action piece in xwork.xml.</p></div><div class="text-center mt-3 text-grey">
