如果在eclipse报出以上内容找不到，则因为没有添加 standard.jar 和jstl.jar的缘故。需要引入这两个jar。尽管在jstl-1.2.jar中可以看到function但还是需要standard.jar
gradle:
compile group: 'javax.servlet', name: 'jstl', version:'1.2'
compile('taglibs:standard:1.1.2')
mvn:
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
<version>1.2</version>
</dependency>
<dependency>
<groupId>taglibs</groupId>
<artifactId>standard</artifactId>
<version>1.1.2</version>
</dependency>
