字体大小: 中小 标准 ->行高大小: 标准 中 大

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tld下的所有tld文件复制到WEB-INF\目录下

　　在web.xml文件中添加

复制代码
 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>

16           <taglib-location>/WEB-INF/x.tld</taglib-location>
17       </taglib>
