我有以下JSP:
<%@ page contentType="text/html" pageEncoding="UTF-8"%>
<%@ taglib uri="http://java.sun.com/jstl/core" prefix="c" %>
<%@ page isELIgnored="false"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title><c:out value="${it.title}"/></title>
</head>
<body>
<c:forEach var="speaker" items="${it.speakers}" varStatus="stat">
<ul>
<li><c:out value="${speaker.person.firstName}" /> <c:out value="${speaker.person.lastName}" />, <c:out value="${speaker.person.address.city.zip}" /> <c:out value="${speaker.person.address.city.name}" /></li>
</ul>
</c:forEach>
</body>
</html>
Eclipse在我的代码中警告我关于EL表达式的每个实例:
Warning [line 10]: "value" does not support runtime expressions
Warning [line 13]: "items" does not support runtime expressions
...
但事实并非如此,EL会被服务器正确评估.
任何人都可以向我暗示正确的方向为什么eclipse会警告我那些EL表达式？
