zepto.min.js

2.後台查詢

/**
 * 我找的劵
 * 
 * @return
 */
 @Action("IFindTicket")
 public String IFindTicket() {
 try {
 FuTransaction transaction = fuTransactionService.findByUserId(userId);
 Map<String, Object> map = new HashMap<String, Object>();
 map.put("transactionId", transaction == null ? 0L : transaction.getId());
 List<FuStockAccount> accounts = fuStockAccountService.findAccountByMap(0, 5, map);
 this.getActionContext().put("accounts", accounts);
 } catch (Exception e) {
 e.printStackTrace();
 logger.equals(e);
 }
 return SUCCESS;
 }

 /**
 * 我找的劵數據
 * 
 * @return
 */
 @Action("findTicketData")
 public String findTicketData() {
 try {
 FuTransaction transaction = fuTransactionService.findByUserId(userId);
 Map<String, Object> map = new HashMap<String, Object>();
 map.put("transactionId", transaction == null ? 0L : transaction.getId());
 List<FuStockAccount> accounts = fuStockAccountService.findAccountByMap(0, Integer.MAX_VALUE, map);
 JSONObject json = new JSONObject();
 JSONArray array = new JSONArray();
 if (accounts.size() > 0) {
 for (FuStockAccount account : accounts) {
  JSONObject obj = new JSONObject();
  obj.put("id", account.getId());
  obj.put("openEquity", account.getOpenEquity());
  obj.put("capitalAccount", account.getCapitalAccount());
  obj.put("transactionStatus", account.getTransactionStatus());
  obj.put("status", account.getTransactionStatus() == 0 ? "正在操作" : "已退劵");
  obj.put("available", new DecimalFormat("#,###,##0.00").format(account.getAvailable() == null ? 0 : account.getAvailable()));
  obj.put("ableMoney", new DecimalFormat("#,###,##0.00").format(account.getAbleMoney() == null ? 0 : account.getAbleMoney()));
  obj.put("createTime", new SimpleDateFormat("yyyy.MM.dd").format(account.getCreateTime()));
  array.add(obj);
 }
 }
 json.put("array", array);
 write(json.toString());
 } catch (Exception e) {
 e.printStackTrace();
 logger.error(e);
 }
 return null;
 }
