1、下载JSTL包

https://archive.apache.org/dist/jakarta/taglibs/standard/binaries/jakarta-taglibs-standard-1.1.2.zip

2、部署

  将lib下的两个jar包复制到WEB-INF\lib\目录下

  将tld下的所有tld文件复制到WEB-INF\目录下

  在web.xml文件中添加

1 <jsp-config> 2 <taglib> 3 <taglib-uri>http://java.sun.com/jsp/jstl/core</taglib-uri> 4 <taglib-location>/WEB-INF/c.tld</taglib-location> 5 </taglib> 6 <taglib> 7 <taglib-uri>http://java.sun.com/jsp/jstl/fmt</taglib-uri> 8 <taglib-location>/WEB-INF/fmt.tld</taglib-location> 9 </taglib> 10 <taglib> 11 <taglib-uri>http://java.sun.com/jsp/jstl/sql</taglib-uri> 12 <taglib-location>/WEB-INF/sql.tld</taglib-location> 13 </taglib> 14 <taglib> 15 <taglib-uri>http://java.sun.com/jsp/jstl/x</taglib-uri> 16 <taglib-location>/WEB-INF/x.tld</taglib-location> 17 </taglib> 18 <taglib> 19 <taglib-uri>http://java.sun.com/jsp/jstl/fn</taglib-uri> 20 <taglib-location>/WEB-INF/fn.tld</taglib-location> 21 </taglib> 22 </jsp-config>

3、应用

  在test.jsp页面中

1 <?xml version="1.0" encoding="UTF-8" ?> 2 <%@ page language="java" contentType="text/html; charset=UTF-8" 3 pageEncoding="UTF-8"%> 4 <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%> 5 <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 6 <html xmlns="http://www.w3.org/1999/xhtml"> 7 <head> 8 <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> 9 <title>JSTL</title> 10 </head> 11 <body> 12 <c:out value="Hello JSTL." /> 13 </body> 14 </html>
