JAVA 中 提取 JSON 字符串中的 KEY 和 VALUE 值

JSONObject jobj = JSONObject.fromObject(conditions == null ? "{}": conditions);Iterator it = jobj.keys();String infotype = "FCCS";while (it.hasNext()) {String key = it.next().toString();// 将所有的空串去掉if (StringUtil.getString(jobj.getString(key)) == null) {continue;}if("infoType".equals(key)){      //试剂类型if("FCCS".equals(jobj.getString(key))){infotype = "FCCS";}else if("HS".equals(jobj.getString(key))){infotype = "HS";}}
