webwork框架
以前都沒有用過WebWork這個框架,只是聽說過.沒想到現在要用,所以就自學了一下.做了個小例子給大家分享下中間遇到的苦難和經驗.?
準備工作:首先要去下載WebWork框架的開發包.我用的2.2.6版本的.
開發過程如下:?
1.建立一個WEB工程.你解壓WebWork的開發包以后會發現有兩個jar文件在第一級目錄里面,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.?
2.在你的web.xml加入下面的代碼:?
<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>?
3.創建你的xwork.xml文件,在里面加入下面代碼:?
<!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"?
?? <result name="yes" type="dispatcher">/yes.jsp</result>?
</action>?
</package>?
</xwork>?
4.創建webwork.properties文件(和xwork.xml放在一個文件夾下),寫入下列代碼?
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?
5.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";?
}?
}?
6.然后在創建下列兩個jsp頁面.?
第一個頁面: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>
到這里就OK了,運行你的項目吧..?
在index.jsp頁面中輸入文字,點提交在yes.jsp頁面給與顯示...
如果你就按照上面這樣做,你會發現會出錯誤.錯誤原因有可能是因為你的tomcat里面解析xml的jar包版本過低.?
解決辦法就是下載xalan.jar文件.?
然后把里面的jar文件都拷貝到tomcat安裝目錄下面的common目錄下的endorsed目錄下...就OK了.
