Freemarker遍历Java的Map

废话不说，看代码：

Java

Map<String, String> selectMap = new TreeMap<String, String>();
selectMap.put("platId", "平台ID");
selectMap.put("crawlerId", "爬虫ID");
request.setAttribute("selectMap", selectMap);

<select>
	<option value="all">所有字段</option>
	<#list selectMap?keys as key>
		<option value="${key}">${selectMap[key]}</option>
	</#list>
</select>
