java 中的一些常用方法

将json格式转换成 对象



super.getJsonUtil().fromJSon(json, PayNoteVO.class);

PayNoteVO : 为实体对象

将日期Fri Jun 24 00:00:00 CST 2016  格式装换成 2016-06-24(String) 格式

String payDateStr = DataFormat.formatDate(new Date().getTime());

String date = StringUtil.formatDate(new Date(),"yyyy-MM-dd");

将json格式转换成 object对象[{id:"23",notesReason:"ssddfhfg"}]

JSONObject jsonObject = new JSONObject().fromObject(json);
   String id = jsonObject.getString("id");
   String reasonRefuse = jsonObject.getString("notesReason");

将bean转换成Map

Map map = new HashMap();
  map.put("DOCID", bean.getDocid());
  map.put("NOTE_TYPE", bean.getNoteType());
  map.put("NOTE_COUNT", bean.getNoteCount());
  map.put("ACCOUNT_NUM", bean.getAccountNum());
  map.put("OPERATE_TYPE", bean.getOperateType());
  map.put("ACTUAL_NOTE_COUNT", bean.getActualNoteCount());
  return map;

将Map转换成bean对象

EbStnNoteApply bean = new EbStnNoteApply();
  bean.setDocid((String) map.get("DOCID"));
  bean.setNoteType((String) map.get("NOTE_TYPE"));
  bean.setNoteCount((Integer) map.get("NOTE_COUNT"));
  bean.setAccountNum((String) map.get("ACCOUNT_NUM"));
  bean.setOperateType((String) map.get("OPERATE_TYPE"));
  bean.setActualNoteCount((Integer) map.get("ACTUAL_NOTE_COUNT"));
  bean.setAtomResult((String) map.get("ATOM_RESULT"));
  bean.setAtomInfo((String) map.get("ATOM_INFO"));
  bean.setAtomDealDt((Date) map.get("ATOM_DEAL_DT"));
  if (map.containsKey("noteList") && map.get("noteList") != null) {
   List> noteList = (List>) map
     .get("noteList");
   for (Map noteInfo : noteList) {
    bean.getNoteList().add(EbStnNoteInfo.mapToBean(noteInfo));
   }
  }
  return bean;
