model域里面存的map嵌套，页面怎么取值？

Answer 1

<c:forEach var="map" items="${systemList}">
<c:forEach items="${map}" var="entry">
<c:choose>
<c:when test="${system==entry.key}">
<option value="${entry.key}" selected="selected">
${entry.value}
</option>
</c:when>

<c:otherwise>
<option value="${entry.key}">
${entry.value}
</option>
</c:otherwise>
</c:choose>

</c:forEach>
</c:forEach>
</select>

上边的是遍历MAP的
