那些年老虎的_温柔
问题描述
我正在开发一个基于 Struts 的应用程序.我是 Struts 的新手.我想在 JSP 页面中使用 html tags ，在 Struts 提供的 taglib 目录中指定.
I am developing a Struts based application. I am new to Struts. I want to use html tags , specified in a taglib directory provided by Struts, in a JSP page.
但是不知道怎么用.我知道如何使用 taglib 指令，但我从消息来源得知 .tld 文件在 1.2.8 版本之后已嵌入到 .jar 文件中.我使用的是 Struts 2.1.8 版.
But don't know how to use it. I know how to use taglib directive but I came to know from sources that the .tld file has been embedded in a .jar file after version 1.2.8. I am using Struts version 2.1.8.
我不知道 struts-html.tld 文件位于哪个 .jar 文件中.
I don't know in which .jar file the struts-html.tld file is located.
推荐答案
我正在使用 Struts 1.3.10 进行此插图:
I'm using Struts 1.3.10 for this illustration:
- 在此处下载最新的 struts 库 (http://www.51sjk.com/Upload/Articles/1/0/333/333364_20221021152537913.jpg请记住，完整分发是您必须下载的内容，因为它包含带有 Struts TLD 的 war 文件.
- 在您的 Web 应用程序中，将您下载的存档文件中的所有 lib 复制到您的 /WEB-INF/lib 文件夹中.
- 对于 JSTL 库(适用于 struts)，请访问此处(http://java.sun.com/products/jsp/jstl/)
- 一旦您拥有 Struts TLD 和 JSTL Tld，请将它们放在 /WEB-INF/tld/ 文件夹下(它必须位于/WEB-INF/文件夹).
在 web.xml 上添加以下内容(在 <web-app> 元素下)
- Download the latest struts library here (http://www.51sjk.com/Upload/Articles/1/0/333/333364_20221021152537913.jpg Remember, the Full Distribution is that what you have to download as it contains a war file with the Struts TLD's.
- On your web application, copy all the lib in the archive file you downloaded to your /WEB-INF/lib folder.
- For JSTL libraries (which works well with struts) go here (http://java.sun.com/products/jsp/jstl/)
- Once you have your Struts TLD's and JSTL Tld's, put them under the /WEB-INF/tld/ folder (it must be situated in the /WEB-INF/ folder).
On web.xml add the following stuff (under the <web-app> element)
<jsp-config>

</jsp-config>
这表明一旦你从 JSP 调用你的 TLD，你的 webapp 将寻找匹配的
This tells that once you call your TLD from the JSP, your webapp will look for the matching <taglib-uri> then look for it's location on <taglib-location> and find relevant class to call.
在您的 JSP 上，现在您可以这样做:
On your JSP, now you can do this:
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %> <%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %> <%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="logic" %> <%@ taglib uri="/WEB-INF/struts-layout.tld" prefix="layout"%> <%@ taglib uri="http://www.51sjk.com/Upload/Articles/1/0/333/333364_20221021152557361.jpg" prefix="c" %> <%@ taglib uri="http://www.51sjk.com/Upload/Articles/1/0/333/333364_20221021152558524.jpg" prefix="fmt" %> <%@ taglib uri="http://www.51sjk.com/Upload/Articles/1/0/333/333364_20221021152559461.jpg" prefix="fn" %>
希望这会有所帮助.
