idea jsp无法加载<c:foreach>循环遍历数据

1.首先检查自己是否导入依赖

 <!-- JSTL -->
    <dependency>
      <groupId>javax.servlet</groupId>
      <artifactId>jstl</artifactId>
      <version>1.2</version>
    </dependency>
    <!-- JSTL实现包 -->
    <dependency>
      <groupId>org.apache.taglibs</groupId>
      <artifactId>taglibs-standard-impl</artifactId>
      <version>1.2.5</version>
    </dependency>

2.在jsp加入

<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<%@ page isELIgnored="false" %>

至此问题解决
