子目录中的JSP标记文件，使用单个taglib前缀.那可能吗? [英] JSP Tag Files in subdirectories, using a single taglib prefix. Is that possible?
问题描述
我目前的.tag文件声明为:
I currently have my .tag files declared with:
<%@taglib prefix="t" tagdir="/WEB-INF/tags" %>
标记文件路径的示例:
/WEB-INF/tags/test.tag
我像这样使用它们:
<t:test oneAttributeKey="oneAttributeValue">
some content...
</t:test>
我的问题:我不想将我的所有标记文件放在一个 文件夹中，即"/WEB-INF/tags".
My problem : I don't want to put all my tag files in one single folder, "/WEB-INF/tags".
我希望将它们放在不同的子目录中:
I would prefere to have them in different subdirectories :
/WEB-INF/tags/users/
/WEB-INF/tags/users/
/WEB-INF/tags/widgetsA/
/WEB-INF/tags/widgetsA/
/WEB-INF/tags/widgetsB/
/WEB-INF/tags/widgetsB/
(...)
是否为每个人都创建一个不同的taglib前缀，这是否可能?
我想避免的例子:
<%@taglib prefix="t_users" tagdir="/WEB-INF/tags/users" %>
<%@taglib prefix="t_widgetsA" tagdir="/WEB-INF/tags/widgetsA" %>
<%@taglib prefix="t_widgetsB" tagdir="/WEB-INF/tags/widgetsB" %>
使用单个"t"前缀的示例:
Example of what I would like, using a single "t" prefix :
<t:users/onetag oneAttributeKey="oneAttributeValue">
some content...
</t:users/onetag>
是否存在类似的解决方案?
Does a similar solution exist?
更新:BalusC显示通过在单个.tld中定义所有标记文件，可以仅使用一个前缀.我想我的问题当时还不够清楚:我想知道是否可以在多个子目录中使用标记文件，而不必为元素中的每个 anywhere 指定路径，而在元素中除外会使用它们(例如:< t:users/onetag")！
UPDATE : BalusC showed it's possible to use one prefix only, by defining all the tag files in a single .tld. I guess my question was not clear enough then : I'd like to know if it's possible to use the tag files in multiple subdirectories, without having to specify a path to each of them anywhere except in the element that use them (ex: "<t:users/onetag")!
我对JSP标签不满意的是，即使它们实际上共享非常相似的内容，它们的行为也与常规JSP文件完全不同.实际上，我什至决定将所有jsp文件都放在/WEB-INF/tags/文件夹中，因此它们与标记文件并排放置(为此，我必须选择/WEB-INF/tags/，因为出于某些原因，文件夹对于标签文件是必填的！我不明白为什么我的某些包含HTML的文件会放在/WEB-INF/jsp/中，而另一些文件会放在/WEB-INF/tags/中！！
What I do not like about JSP Tags is that they act very differently than regular JSP files, even if they actually share very similar content. In fact, I even decided to put all my jsp files inside the /WEB-INF/tags/ folder, so they are side to side with the tag files (I had to choose /WEB-INF/tags/ for that, since this folder is mandatory for the tag files, for some reason)! I don't understand why some of my files containing HTML would go in /WEB-INF/jsp/ and some others in /WEB-INF/tags/!!
我希望能够将jsp和标记文件分组到目录中，具体取决于它们的相关性！例子:
I want to be able to group the jsp and tag files into directories, depending of what they are related to! Example :
/WEB-INF/tags/users/userProfileLayout.tag
/WEB-INF/tags/users/employeeProfile.jsp
/WEB-INF/tags/users/employerProfile.jsp
/WEB-INF/tags/widgetsA/widgetALayout.tag
/WEB-INF/tags/widgetsA/oldWidgetA.jsp
/WEB-INF/tags/widgetsA/newWidgetA.jsp
但这迫使我在多个@tablib或.tld中声明每个子目录的路径，这给我带来了一些不便.我会接受，但我认为它可以改进.
But this forces me to declare the path of each of the subdirectories, in multiple @tablib or in a .tld, which I find a little bit inconvenient. I'll live with it, but I think it could be improved.
推荐答案
在放入/WEB-INF文件夹的单个.tld文件中，将它们定义为<tag-file>.
Define them as <tag-file> in a single .tld file which you put in /WEB-INF folder.
例如/WEB-INF/my-tags.tld
<?xml version="1.0" encoding="UTF-8" ?>
<taglib
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-jsptaglibrary_2_1.xsd"
version="2.1"
>
<display-name>My custom tags</display-name>
<tlib-version>1.0</tlib-version>
<short-name>my</short-name>
<uri>http://example.com/tags</uri>
<tag-file>
<name>foo</name>
<path>/WEB-INF/tags/users/foo.tag</path>
</tag-file>
<tag-file>
<name>bar</name>
<path>/WEB-INF/tags/widgetsA/bar.tag</path>
</tag-file>
<tag-file>
<name>baz</name>
<path>/WEB-INF/tags/widgetsB/baz.tag</path>
</tag-file>
</taglib>
按如下所示在您的JSP中使用它
Use it in your JSPs as follows
<%@taglib prefix="my" uri="http://example.com/tags" %>
...
<my:foo />
<my:bar />
<my:baz />
