JSON字符串转成map解析

json字符串格式：{"山东":13,"台湾":32,"福建":16,"河北":5,"河南":7,"重庆":4,"湖北":17,"湖南":18,"江西":21,"海南":23}

要转成list<Map> 格式

import net.sf.json.JSONArray;
import net.sf.json.JSONObject;



String provinceString = "[" +provinceResultJson.get("result").toString()+"]";
JSONArray provinceArray = JSONArray.fromObject(provinceString);
@SuppressWarnings("unchecked")
List<Map<String, Object>> provinceListJson = (List<Map<String, Object>>) provinceArray;
 for (int i = 0; i < provinceListJson.size(); i++) {
    Map<String, Object> obj = provinceListJson.get(i);
    for (Entry<String, Object> entry : obj.entrySet()) {
       String strkey1 = entry.getKey();
       Object strval1 = entry.getValue();
       System.out.println("KEY:" + strkey1 + "  -->  Value:" + strval1 +"\n");
     }
 }

在jsp页面的遍历

<select id="provinceId" name="provinceId" required>
   <option value="">-=请选择一项=-</option>
       <c:forEach var="list" items="${provinceListJson}" varStatus="number">
              <c:forEach items="${list}" var="map">
                 <option value="${map.value}">${map.key}</option>
             </c:forEach>
       </c:forEach>
</select>

       在JS遍历

var cityMap = eval(result.data);
     for (var j=0;j<cityMap.length;j++) {
         　$.each(cityMap[j],function(key,value){
           cityOptionHtml += '<option value="'+value +'">' + key +'</option>';
           });
        }
