ECLIPSE TOMCAT CONFIG JSTL

{LJ?Dragon}【标题】Eclipse 配置 JSTL标签库

{LJ?Dragon}【Diary】2017年，愉快的开始；当和他们离别时，感觉失去了整个世界.........

 

1.JSTL简介

JSTL--JSP Standard Tag Library（JSP标准标签库），由JCP（Java Community Process）制订，它是一组形如HTML的标签，让入门者无须Java学习也可编写动态WEB页

2.使用步骤

要下载JSTL所需的JAR包，并在eclipse中完成配置，才可以使用

1、进官网下载

网址：http://archive.apache.org/dist/jakarta/taglibs/standard/binaries/

2.添加Jar包

解压后将jstl.jar和standard.jar两个包拖到你新建的Dynamic WEB工程的lib文件夹中即可

3.说明

网上很多教程说要在web.xml中配置

web.xml

1. <?xml version="1.0" encoding="UTF-8"?>
2. <web-app
   xmlns="http://java.sun.com/xml/ns/javaee"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
3.    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
4.                       http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
5.    version="3.0"
   metadata-complete="true">
6.  
7.    <jsp-config>
8.  
9.       <taglib>
10.          <taglib-uri>http://java.sun.com/jstl/fmt</taglib-uri>
11.          <taglib-location>/WEB-INF/fmt.tld</taglib-location>
12.       </taglib>
13.  
14.       <taglib>
15.          <taglib-uri>http://java.sun.com/jstl/core</taglib-uri>
16.          <taglib-location>/WEB-INF/c.tld</taglib-location>
17.       </taglib>
18.  
19.       <taglib>
20.          <taglib-uri>http://java.sun.com/jstl/fn</taglib-uri>
21.          <taglib-location>/WEB-INF/fn.tld</taglib-location>
22.       </taglib>
23.  
24.       <taglib>
25.          <taglib-uri>http://java.sun.com/jstl/perTag</taglib-uri>
26.          <taglib-location>/WEB-INF/permittedTaglibs.tld</taglib-location>
27.       </taglib>
28.  
29.       <taglib>
30.          <taglib-uri>http://java.sun.com/jstl/sql</taglib-uri>
31.          <taglib-location>/WEB-INF/sql.tld</taglib-location>
32.       </taglib>
33.  
34.       <taglib>
35.          <taglib-uri>http://java.sun.com/jstl/script</taglib-uri>
36.          <taglib-location>/WEB-INF/scriptfree.tld</taglib-location>
37.       </taglib>
38.  
39.       <taglib>
40.          <taglib-uri>http://java.sun.com/jstl/x</taglib-uri>
41.          <taglib-location>/WEB-INF/x.tld</taglib-location>
42.       </taglib>
43.  
44.    </jsp-config>
45. </web-app>

若<jsp-config>...</jsp-config>这一段没加，导致后面运行时提示：cvc-complex-type.2.4.a: Invalid content was found starting with element 'taglib'错误

不过我没配置这些代码好像也可以使用耶...........
