自定义标签

3 月,跳不动了?>>> 一、概述 JSP 2.0 中提供了两种新的开发自定义标记的方法: 1、简单标签机制SimpleTag JSP 2.0 中加入了新的创建自定义标记的API:javax.servlet.jsp.tagext.SimpleTag,该API 定义了用来实现简单标记的接口。和JSP 1.2 中的已有接口不同的是,SimpleTag 接口不使用doStartTag()和doEndTag()方法,而提供了一个简单的doTag()方法。这个方法在调用该标记时只被使用一次。一个自定义标记中实现的所有逻辑都在这个方法中实现。相对JSP1.2 中自定义标记机制,SimpleTag 的方法和处理周期要简单得多。 2、 标签文件 标签文件允许JSP 网页作者使用JSP 语法创建可复用的标签库。标签文件的扩展名必须是.tag。 1.1 使用简单标签机制 与JSP1.2 相似,开发自定义标签要遵循“开发标记类---配置TLD 文件----在JSP 中使用”的过程, 示例如下: 步骤一:编写标记处理类AddTag.java package tag; import java.io.IOException; import javax.servlet.jsp.JspContext; import javax.servlet.jsp.JspException; import javax

http://stackoverflow.com/questions/13428788/according-to-tld-or-attribute-directive-in-tag-file-attribute-items-does-not-ac Your JSTL taglib URI is wrong. The one which you've there is for legacy JSTL 1.0. Since JSTL 1.1 there's an additional /jsp path in the taglib URI, because expression language (those ${} things) has been moved from JSTL to JSP and hence taglibs of JSTL 1.0 and 1.1 are not interchangeable. 如果原因是如上,则把下面的 <%@ taglib uri='http://java.sun.com/jstl/core' prefix='c'%>修改为 <%@ taglib uri='http://java.sun.com/jsp/jstl/core' prefix='c'%> 来源: https://www.cnblogs.com/SamuelSun/p

jsp caching tag library

主宰稳场 提交于 2020-01-04 04:03:07
问题 I want to cache some portions of my JSP page because it is heavy to render. The whole page cannot be cached as it contains user specific content, but most of it can. I thought the best solution would be to create a JSP cache tag. It seems there are several solutions for that but most of these projects are dead or abandoned http://www.opensymphony.com/oscache/ http://jakarta.apache.org/taglibs/doc/cache-doc/ http://www.servletsuite.com/servlets/cachetag.htm I am wondering if there is any

OpenCV where is tracking.hpp

安稳与你 提交于 2020-01-02 04:47:05
问题 I want to use an OpenCV's implementation of the TLD tracker. Internet says that I have to include this file: opencv2/tracking.hpp (e.g. see https://github.com/Itseez/opencv_contrib/blob/master/modules/tracking/samples/tracker.cpp). But there is no such a file. Well, what must I do to use TrackerTLD in my C++ project? (OpenCV 3.0.0 beta for Windows, installed from the .exe package from opencv.org) 回答1: As Floyd mentioned, to use TrackerTLD, you need to download OpenCV contrib repo. Instruction

Extraction of TLD from urls and sorting domains and subdomains for each TLD file

若如初见. 提交于 2019-12-30 11:34:09
问题 I have a list of million urls. I need to extract the TLD for each url and create multiple files for each TLD. For example collect all urls with .com as tld and dump that in 1 file, another file for .edu tld and so on. Further within each file, I have to sort it alphabetically by domains and then by subdomains etc. Can anyone give me a head start for implementing this in perl? 回答1: Use URI to parse the URL, Use its host method to get the host, Use Domain::PublicSuffix's get_root_domain to

Python code to determine if TLD exists, prompt again if not?

房东的猫 提交于 2019-12-24 10:55:34
问题 This is an additional question in regards to this post: Python raw_input with forced TLD? I have a check in place to see if a string ends with a TLD, TLD = ('.com', '.info', '.org', '.net') if raw_input("Please enter a hostname").endswith(TLD): # blah blah But I am attempting to store the raw_input in to a variable. Would the proper coding practice be to do something such as: TLD = ('.com', '.info', '.org', '.net') hostName = raw_input(":").lower() <<piece of code that determines if hostName
