quickFix 子组解析失败

Question

您好，我在捕获 TradeCaptureReport

时无法将 NoPartyIds(443) 组加入我的 NoSides 组

Iterator<Integer> groupIterator= message.groupKeyIterator();

    while (groupIterator.hasNext()) {
        int num = groupIterator.next();
        List<Group> groups = message.getGroups(num);
        log.info("Group Number:"+num+", Groups:"+groups);
        for (Group groupInLoop : groups) {
            quickfix.fix50sp2.TradeCaptureReport.NoSides noSidesGroup = new quickfix.fix50sp2.TradeCaptureReport.NoSides();
            noSidesGroup.setFields(groupInLoop);
            noSidesGroup.get(side);
            noSidesGroup.get(account);
            NoPartyIDs noPartyIDs = new NoPartyIDs();
            noSidesGroup.get(noPartyIDs);
            log.info("side:"+side+", account:"+account+", noPartyIDs:"+noPartyIDs);

            Iterator<Integer> noPartyIDsGroupIterator= noSidesGroup.groupKeyIterator();
            log.info("noSidesGroup.groupKeyIterator(): "+noSidesGroup.groupKeyIterator());
            log.info("noSidesGroup: "+noSidesGroup.toString()+", noSidesGroup.getGroups(453):"+noSidesGroup.getGroups(453));

            log.info("noPartyIDsGroupIterator:"+noPartyIDsGroupIterator);
            while (noPartyIDsGroupIterator.hasNext()) {


                int noPartyIDsNum = noPartyIDsGroupIterator.next();
                List<Group> noPartyIDsGroups = noSidesGroup.getGroups(noPartyIDsNum);
                log.info("Group Number:"+noPartyIDsNum+", Groups:"+noPartyIDsGroups);
                for (Group noPartyIDsGroupInLoop : noPartyIDsGroups) {
                    quickfix.fix50sp2.TradeCaptureReport.NoSides.NoPartyIDs partyIdGroup = new quickfix.fix50sp2.TradeCaptureReport.NoSides.NoPartyIDs();
                    partyIdGroup.setFields(noPartyIDsGroupInLoop);
                    partyIdGroup.get(partyId);
                    partyIdGroup.get(partyRole);
                    log.info("partyId:"+partyId+", partyRole:"+partyRole);
                }
            }


        }

我的 noPartyIDsGroupIterator.hasNext() returns 是空的，什么也没有，但在我的消息中它有字段。

数据字典看起来像：

  </group>
</component>

同样对于 noSidesGroup 内的 noPartyIDs 字段，它给出计数 5，但无法访问此 noPartyIDsgroup 内的元素。

Answer 1

可以通过使用 groupInLoop 作为 noPartyIds 组的迭代器来解析。

Iterator<Integer> noPartyIDsGroupIterator= groupInLoop.groupKeyIterator();
