SAP Cloud SDK (Java) 在 SuccessFactors 元数据加载时抛出命名错误异常

Question

由于 Cloud SDK 抛出异常，我无法继续。云 SDK 的 EdmNamedImpl class 由于 SF 元数据属性名称不正确而引发错误。 SF 实体的属性名称是 "goto-url"，因此由于 PATTER_VALID_NAME 匹配器不接受字段名称中的连字符。我尝试了很多方法，但无法解决此异常。我想 Cloud SDK 要么应该提供一种方法来抑制名称验证，要么提供一种方法来传递本地元数据文件的路径以执行 FluentHelper 的方法。

我构造查询的方式是：

new DefaultAPISuccessFactorsService().withServicePath("<host>/odata/v2").getAllUser().execute(PASSING_SF_DEST_HERE);

执行时，框架在执行实际查询之前从 SF 读取元数据，但元数据读取失败。请参阅下面的代码片段，其中抛出了异常：

Answer 1

不幸的是，我目前看不到解决这个问题的简单方法。 SDK 本身在内部使用另一个库来执行 OData 2.0 请求。图书馆执行元数据请求并在发出实际请求之前对其进行处理。

但是，如 this answer 中所述，连字符在实体标识符中是不合法的。所以这在 SuccessFactors 方面更像是一个问题。

编辑：

有一个测试版 API 不依赖于元数据请求，但需要您手动 assemble 请求：

ODataRequestRead request =
            new ODataRequestRead("<host>/odata/v2", "Users", "", ODataProtocol.V2);
HttpClient client = HttpClientAccessor.getHttpClient(destination);

ODataRequestResult result = request.execute(client);
List<User> users = result.asList(User.class);

但是 API 是完全测试版，需要手动操作并且不支持某些功能。例如。此处未从响应中提取 ETag。所以我建议只有当你真的需要它工作并且可以接受功能差距和不稳定时才使用它 API.
