Question

我正在尝试通过使用Apache Olingo V4从API调用返回的客户端实体进行解析。我看到以下错误，当值字符串包含“ {”或“}”时，即使返回的数据为JSON格式，并且括号中都用引号引起来。

错误：

[main]：2019-03-13 13：52：21,719 ERROR JOID [] JNAME [] [ClientEntitySetIterator]-从EntitySet检索实体时出错 org.apache.olingo.client.api.serialization.ODataDeserializerException：com.fasterxml.jackson.core.JsonParseException：VALUE_STRING中意外的输入结束

代码

URIBuilder uriBuilder = client.newURIBuilder(url).appendEntitySetSegment("Orders");
    uriBuilder.addCustomQueryOption("$filter", filter.toString());
    uriBuilder.addCustomQueryOption("exported", "false");
    uriBuilder.addCustomQueryOption("$count", "true");
    URI absoluteUri = uriBuilder.build();

    ODataEntitySetIteratorRequest<ClientEntitySet, ClientEntity> request = 
            client.getRetrieveRequestFactory().getEntitySetIteratorRequest(absoluteUri);
    request.addCustomHeader(HttpHeader.AUTHORIZATION, "Bearer "+token);
    request.addCustomHeader("exported", "false");
    request.setFormat(ContentType.APPLICATION_JSON);
    request.setAccept("application/json;odata.metadata=minimal");

    ODataRetrieveResponse<ClientEntitySetIterator<ClientEntitySet, ClientEntity>> response = request.execute();

    int res = response.getStatusCode();
    String message = response.getStatusMessage();

    ClientEntitySetIterator<ClientEntitySet, ClientEntity>  iterator = response.getBody();

    while(iterator.hasNext()) {
        ClientEntity ce = iterator.next();
        ClientEntityImpl impl = (ClientEntityImpl) ce;
        String shippingStatus = impl.getProperty(SHIPPINGSTATUS).getValue().toString();
        String checkoutStatus = impl.getProperty(CHECKOUTSTATUS).getValue().toString();
        String paymentStatus = impl.getProperty(PAYMENTSTATUS).getValue().toString();
    }

如果返回的订单在value语句中包含“ {”或“}”，则在while循环开始时在iterator.hasNext（）位置抛出错误。如果发生这种情况，即使剩余实体在value语句中不包含括号，也不会处理。有没有一种方法可以不使用ODataRetrieveResponse迭代器来处理该实体，或者跳过该实体并处理所有剩余实体？
