后端代码：

public void show_main(){

String token = this.getPara("token");

JSONObject json = new JSONObject();

json.put("token", token);

json.put("resultMap", new JSONArray());

this.setAttr("loginData", json);·

renderFreeMarker("index.html");

}

前端JSP代码：

<#list loginData.resultMap as jspider>

<li><div class="photo"><a href="/news/show"><img src="../images/1.jpg" /></a></div><div class="txt"><a href=""></a></div></li>

</#list>

报错：

For "#list" list source: Expected a collection or sequence, but this evaluated to an extended_hash+string (org.json.JSONArray wrapped into f.e.b.StringModel):

==> loginData.resultMap [in template "WEB-INF/index.html" at line 228, column 8]
