合计数值的问题

一开始总是报错Integer.parseInt java.lang.NumberFormatException: For input string:，查询是转换的问题，list拿到的是Object类型，多次转换计算数值，中间出错

 public Result collectionStatistics(AccountRechargeRequest request) {
        LoggerUtils.infoData("/collectionStatistics", request);
        var list = databaseDao.statementDao.collectionStatistics(request);
        var eid = "employee_id";
        HashMap sumMap = new HashMap();
        for (var e : list) {
            if (e.containsKey(eid)) {
                e.put("name", SystemConfigService.findEmployeeName(Integer.parseInt(e.get(eid).toString())));
            } else {
                e.put("name", "其他");
            }
        }

        var r = new Result(list);
        ArrayList> result = new ArrayList<>();
        for (int i = 0; i < list.size(); i++) {
            var map = new HashMap();
            var e = list.get(i);
            map.put("sum", e.get("sum") == null ? e.get("sum") : BigDecimal.valueOf(Double.parseDouble(e.get("sum").toString())).divide(BigDecimal.valueOf(1)));
            result.add(map);
        }
        double sumSalesVolume = result.stream().mapToDouble(e -> Double.valueOf(e.get("sum") == null ? "0" : e.get("sum").toString())).sum();
        DecimalFormat format = new DecimalFormat("0");
        Object sum = format.format(sumSalesVolume);
        sumMap.put("sumMap", sum);
        r.setSumMap(sumMap);
        return r;
    }
