Json转Map

http = new HttpClient**();//此处封装一下发请求的类
Map<String, String> map = new HashMap<String, String>();
map.put("sql", sql);
JSONObject json = JSONObject.fromObject(vMap);
map.put("vMap", json.toString());
http.post(url+ "/common***/action/save.action", map);
String str = "";
if (http.getResponse().getStatus() == 200) {
try {
str = http.getResponse().getBody();
}catch (Exception e1) {
e1.printStackTrace();
throw new Exception("未取到元数据");
}
}
return str;

服务器端Action接收：

String sql = request.getParameter("sql");
String str = request.getParameter("valueMap");

方法：

public static Map parserToMap(String s){
Map map=new HashMap();
JSONObject json=JSONObject.fromObject(s);
Iterator keys=json.keys();
while(keys.hasNext()){
String key=(String) keys.next();
String value=json.get(key).toString();
if(value.startsWith("{")&&value.endsWith("}")){
map.put(key, parserToMap(value));
}else{
map.put(key, value);
}
}
return map;
}
