Question

spring中使用<c:forEach>标签报错

引入标签<%@ taglib uri="http://java.sun.com/jstl/core" prefix="c"%>
输出整个List也有值 一遍历就出下面的报错信息
报错信息：
HTTP Status 500 - An exception occurred processing JSP page /WEB-INF/jsp/messageList.jsp at line 109
type Exception report
message An exception occurred processing JSP page /WEB-INF/jsp/messageList.jsp at line 109
description The server encountered an internal error that prevented it from fulfilling this request.
exception org.apache.jasper.JasperException: An exception occurred processing JSP page /WEB-INF/jsp/messageList.jsp at line 109

106:
107: <tr>
108: <td class="tc"><input name="id[]" value="59" type="checkbox"></td>
109: <td>${messageList.id}</td>
希望高手给解答一下 感激不尽

你看一下你的messageList对象里面有东西么，没东西的话这么写当然报错
