java - 使用java仅添加一个值的列表对象

Question

我正在尝试将一个引导 ID(字符串)添加到列表对象中。最初它在 while 循环中迭代，无论哪个引导 ID 为空。我将该引导 ID 添加到列表对象中。完成迭代后，该列表对象仅处理最后一个失败的引导 ID。事实上它也应该有其他字符串。

这是我的代码。

 while(iterLeadIds.hasNext()) {
        String leadId = (String) iterLeadIds.next();
        BankBridgeServiceRequest bankBridgeServiceRequest = new BankBridgeServiceRequest();
        bankBridgeServiceRequest.setLeadId(leadId);
        bankBridgeServiceRequest.setType(BankBridgeMethodType.webservice_Create_Lead);
        LOG.info("Sending to web service Rev Lead ID = " + bankBridgeServiceRequest.getLeadId());
        bankBridgeServiceResponse = bankBridgeService.run(bankBridgeServiceRequest);
        String responseString = bankBridgeServiceResponse.getResponseString();
        List<String> list = new ArrayList<String>();
        if(responseString == null) {
            bankBridgeUtilResponse.setStatus(false);
            list.add(leadId);
            bankBridgeUtilResponse.setFailedLeadIds(list);
            LOG.info("webservice Rev got null response from Lead ID ::"+leadId);

“列表”对象应该有许多失败的潜在客户 ID。

有什么改变吗？

谢谢

您的问题是您在循环内创建列表，因此列表仅包含您添加的最后一个元素。

移动这个:

List<String> list = new ArrayList<String>();

在循环之前:

List<String> list = new ArrayList<String>();
while(iterLeadIds.hasNext()) {
        String leadId = (String) iterLeadIds.next();
        BankBridgeServiceRequest bankBridgeServiceRequest = new BankBridgeServiceRequest();
        bankBridgeServiceRequest.setLeadId(leadId);
        bankBridgeServiceRequest.setType(BankBridgeMethodType.webservice_Create_Lead);
        LOG.info("Sending to web service Rev Lead ID = " + bankBridgeServiceRequest.getLeadId());
        bankBridgeServiceResponse = bankBridgeService.run(bankBridgeServiceRequest);
        String responseString = bankBridgeServiceResponse.getResponseString();
        if(responseString == null) {
            bankBridgeUtilResponse.setStatus(false);
            list.add(leadId);
            bankBridgeUtilResponse.setFailedLeadIds(list);
            LOG.info("webservice Rev got null response from Lead ID ::"+leadId);
