我已尝试查看有关同一问题的许多其他类似问题，但我无法解决。
我正在尝试将地图的密钥与JSONObject的名称进行比较，但它给出了以下错误，

这是我写的代码，
<body>
<c:forEach var="resultValue" items="${seatMap}">
<c:forEach var="trainValue" items="${trainList}">
<c:if test="${resultValue.key} == ${trainValue.get("number")}">
<div>
${trainValue.get("no")}
${trainValue.get("number")}
${trainValue.get("name")}
${trainValue.get("from").get("name")}
<br><br><br>
</div>
</c:if>
</c:forEach>
</c:forEach>
</body>
这里的seatMap是map<String,List<JSONObject>，trainList是List<JSONObject>。
第13行是<c:if test="${resultValue.key} == ${trainValue.get("number")}">
请帮帮我。
