Answer 1

1. 确定你的页面导入了 c 标签: 
  <%@ taglib uri="http://java.sun.com/jstl/core" prefix="c"%>2. 如果已经导入了 c 标签, 也就是页面已经包含了上面的 tablib 语句;那么,请将如上的语句换成:
  <%@ taglib uri=http://java.sun.com/jstl/core_rt prefix="c"%> 

Answer 2

楼主估计导入是1.0的标签，修改成这样1.1
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
