JSTL taglib URI已经过时了？ [英] JSTL taglib URI is obsolete?
问题描述
<％@ page会话= 假 ％GT;
<％@ taglib prefix =curi =http://java.sun.com/jsp/jstl/core％>
< html>
< head>< title> Training，Inc.< / title>< / head>
< body>
< h2>< c：out value =$ {message}/>< / h2>
< / body>
< / html>
有一个字符串设置为消息，c：out标签只是打印字面上
$ {message}
我正在打我的头一会儿，直到我记得一个问题之前已将taglib URI更改为：
<％@ taglib prefix =curi =http：// java.sun.com/jstl/core％>
这解决了我的小问题
很久以前，我有一个与XSLT转换相似的问题，但在这种情况下，我必须从 http：/ /java.sun.com/jstl/xml 到 http ：//java.sun.com/jsp/jstl/xml
根据这个链接我的春天的例子应该像从Spring教程粘贴一样工作
问题是：
你们中的任何人都知道这个taglib URI混淆在哪里记录？为什么在某些情况下，我得到了 http://java.sun.com/jsp/jstl ，其他的我从 http://java.sun.com/jstl
如果你仍然收到这个错误，但是你手工制作你的pom，你可能错过了标准图书馆。
例如我错过了
<依赖关系>
< groupId> taglibs< / groupId>
< artifactId> standard< / artifactId>
< version> $ {jstl.version}< / version>
< / dependency>
I've been checking out Spring MVC tutorial and copied this small JSP code from there:
<%@ page session="false"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<html>
<head><title>Training, Inc.</title></head>
<body>
<h2><c:out value="${message}" /></h2>
</body>
</html>
There is a string set for message and the c:out tag just prints literally
${message}
I was hitting my head for a while until I remembered an issue I had before and changed the taglib URI to:
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core" %>
This solved my little problem
Some time ago I had a similar issue with XSLT transforming but in that case I had to change from http://java.sun.com/jstl/xml to http://java.sun.com/jsp/jstl/xml
According with this link my spring example should've worked just as I pasted from spring tutorial
The question is: Any of you guys know where is all this taglib URI confusion documented? Why in the some cases I got the last version from http://java.sun.com/jsp/jstl and in other ones I got the last version from http://java.sun.com/jstl
If you're still getting this error, but you're hand crafting your pom, you probably have missed the standard library. e.g. I'd missed
<dependency>
<groupId>taglibs</groupId>
<artifactId>standard</artifactId>
<version>${jstl.version}</version>
</dependency>
