Odata 查询批量请求 - 过滤器不工作

Question

我们正在使用 SAP SDK 3.25.0 并调用批处理请求读取查询传递一些过滤器。我得到了所有记录的响应，可以看出过滤器没有正常工作。

我已经引用了这个博客 here 但我遇到了同样的解码问题 URL 问题 YY1_QuantityContractTracki?$filter=((CustomerName eq %27Ford%27) and (SalesSchedulingAgreement eq %270030000141%27)) and (PurchaseOrderByCustomer eq %27TEST%27)&$select=SalesSchedulingAgreement,PurchaseOrderByCustomer,Customer,CustomerName,SalesSchedulingAgreementItem,Material,MaterialByCustomer&$format=json

下面是我正在使用的查询程序。

我是不是漏掉了什么。请告诉我们谢谢，阿润派

final BatchRequestBuilder builder = BatchRequestBuilder.withService("/sap/opu/odata/sap/YY1_QUANTITYCONTRACTTRACKI_CDS");
    for (Contract contract : contracts) {
        FilterExpression mainFilter = new FilterExpression("CustomerName", "eq", ODataType.of(contract.getCustomerName()))
                .and(new FilterExpression("SalesSchedulingAgreement", "eq", ODataType.of(contract.getSchAgrmntNo())))
                .and(new FilterExpression("PurchaseOrderByCustomer", "eq", ODataType.of(contract.getCustRefNo())));
        final ODataQuery oDataQuery = ODataQueryBuilder
                .withEntity(sapConfig.getEssentialsContractServiceUrl(),
                        sapConfig.getEssentialsContractListEntity())
                .select("SalesSchedulingAgreement", "PurchaseOrderByCustomer", "Customer", "CustomerName",
                        "SalesSchedulingAgreementItem", "Material", "MaterialByCustomer")
                .filter(mainFilter)
                .build();
        builder.addQueryRequest(oDataQuery);
    }
    final BatchRequest batchRequest = builder.build();
    final BatchResult batchResult = batchRequest.execute(httpClient);

更新

我今天将版本更改为 3.35.0，连接版本为 1.40.11，但它也没有用。下面是在控制台中打印的日志请求

更新 (22.03.2021)

同release of SAP Cloud SDK 3.41.0 this week we'll enable support for read operations in OData batch requests on the type-safe API. Please find the chapter in the respective documentation。示例：

BusinessPartnerService service;
BusinessPartnerAddress addressToCreate1;
BusinessPartnerAddress addressToCreate2;

BusinessPartnerFluentHelper requestTenEntities = service.getAllBusinessPartner().top(10);
BusinessPartnerByKeyFluentHelper requestSingleEntity = service.getBusinessPartnerByKey("bupa9000");

BatchResponse result =
    service
        .batch()
        .addReadOperations(requestTenEntities)
        .addReadOperations(requestSingleEntity)
        .executeRequest(destination);

List<BusinessPartner> entities = result.getReadResult(requestTenEntities);
BusinessPartner entity = result.getReadResult(requestSingleEntity);

我来自SAP Cloud SDK team. Generally we recommend our users to generate classes for their OData service interactions。通过这种方式，您可以轻松确保请求符合规范，同时注意类型安全。

很遗憾，我无法帮助您解决 BatchRequestBuilder、BatchRequest 或 BatchResult 的 API，因为它们不直接属于 SAP Cloud SDK 且不由我们维护。相反，我们建议我们自己的请求构建器。

如果上面链接的类的生成不适合您，那么我建议您试试我们的专家 API，其特点是 Generic OData Client SAP Cloud SDK。这是我们也将在内部用于我们生成的请求构建器的代码：

String servicePath = "/sap/opu/odata/sap/YY1_QUANTITYCONTRACTTRACKI_CDS";
ODataRequestBatch requestBatch = new ODataRequestBatch(servicePath, ODataProtocol.V2);
Map<Contract, ODataRequestRead> batchedRequests = new HashMap<>();

// iterate over contracts, construct OData query objects and add them to the OData batch request builder
for (Contract contract : contracts) {
    String entityName = sapConfig.getEssentialsContractListEntity();
    String serviceUrl = sapConfig.getEssentialsContractServiceUrl();
    StructuredQuery structuredQuery = StructuredQuery.onEntity(entityName, ODataProtocol.V2);

    structuredQuery.select("SalesSchedulingAgreement", "PurchaseOrderByCustomer", "Customer", "CustomerName", "SalesSchedulingAgreementItem", "Material", "MaterialByCustomer");
    structuredQuery.filter(FieldReference.of("SalesSchedulingAgreement").equalTo(contract.getSchAgrmntNo()));
    structuredQuery.filter(FieldReference.of("PurchaseOrderByCustomer").equalTo(contract.getCustRefNo()));

    String encodedQuery = structuredQuery.getEncodedQueryString();
    ODataRequestRead requestRead = new ODataRequestRead(serviceUrl, entityName, encodedQuery, ODataProtocol.V2);
    batchedRequests.put(contract, requestRead);
    requestBatch.addRead(requestRead);
}

// execute the OData batch request
ODataRequestResultMultipartGeneric batchResult = requestBatch.execute(httpClient);

// extract information from batch response, by referring to the individual OData request references
for( Map.Entry<Contract, ODataRequestRead> requestMapping : batchedRequests.entrySet() ) {
    ODataRequestResultGeneric queryResult = batchResult.getResult(requestMapping.getValue());
    List<Map<String, Object>> itemsForQuery = queryResult.asListOfMaps();
}

供参考：同release of SAP Cloud SDK 3.41.0 we enabled support for read operations in OData batch requests on the type-safe API. Please find the chapter in the respective documentation. You would no longer need to use the Generic OData Client of SAP Cloud SDK as suggested in 。示例：

BusinessPartnerService service;
BusinessPartnerAddress addressToCreate1;
BusinessPartnerAddress addressToCreate2;

BusinessPartnerFluentHelper requestTenEntities = service.getAllBusinessPartner().top(10);
BusinessPartnerByKeyFluentHelper requestSingleEntity = service.getBusinessPartnerByKey("bupa9000");

BatchResponse result =
    service
        .batch()
        .addReadOperations(requestTenEntities)
        .addReadOperations(requestSingleEntity)
        .executeRequest(destination);

List<BusinessPartner> entities = result.getReadResult(requestTenEntities);
BusinessPartner entity = result.getReadResult(requestSingleEntity);
