Java 使用SAP Cloud SDK版本3.2.0向OData服务发送POST请求

我正在开发一个使用SAP Cloud SDK的应用程序。我以前使用的是SAP Cloud SDK的版本2.20.1，并向OData服务发送了POST请求。这是我用来发送POST请求的代码：

final ODataCreateRequestImpl createRequest =
            new ODataCreateRequestImpl("/sap/opu/odata/sap/ZAS_BP_CREATION_SRV",
                    "BP_DATASet", bodyAsMap, null, null, null, headersAsMap, null, false, null, null, false);

    JSONObject jsonResponse = null;

    try {

        Map<String, Object> resp = createRequest.execute("ErpQueryEndpoint").asMap();
        jsonResponse = new JSONObject(resp);

    } catch(final ODataException e) {
        logger.error(e.getMessage(), e);
    }
    catch(final JSONException e) {
        logger.error(e.getMessage(), e);
    }

一个记录良好的问题！不幸的是，云SDK（

com.sap.cloud.SDK.

）中附带的Service SDK（

com.sap.cloud.servicesdk.*

）版本似乎存在一些以前未跟踪到的内部依赖兼容性问题

解决方案： 请尝试版本

3.9.0

（或更高版本），而不是云SDK版本

3.2.0

。该问题已在该更新中修复。不要担心版本号的跳跃。我不希望您的应用程序代码出现兼容性问题

---

或者，如果您确实希望继续使用版本

3.2.0

，则可以在POM中手动添加兼容的Service SDK依赖项版本，例如

1.35.2

（或更高版本）

基本上有两种解决问题的方法：

通过我们的Maven插件创建您自己的OData VDM。这样，您就可以获得对服务的类型安全访问，而不必为请求中的字符串操心。对于一个粗略的指南，您可以遵循，但请注意，它是为SDK的版本2编写的。我们正在更新第3版的博客文章，但目前您必须自己迁移它（不应该比更改groupId和artifactId更多）

改用

execute（HttpClient）

方法，例如：

//altenactive在运行时创建目标：
//HttpDestination=DefaultHttpDestination.builder（“https://www.google.debuild（）；
HttpDestination=DestinationAccessor.getDestination（“ErpQueryEndpoint”）.asHttp（）；
HttpClient HttpClient=HttpClientAccessor.getHttpClient（目的地）；
Map resp=createRequest.execute（httpClient.asMap（）；

这应该会顺利通过

非常感谢你的回答，亚历克斯。不幸的是，更改版本也会发生同样的情况，从ODataCreateRequestImpl类调用HttpClientAccessor类的getHttpClient方法时，将destinationName参数作为字符串传递，但是在HttpClientAccessor类中，getHttpClient方法接收的目标参数是HttpDestinationProperties，而不是String。我还尝试将SAP Cloud SDK的版本更改为3.9.0。非常感谢您的回复，舒伯特。我尝试了您指出的第二个选项，但是，出于相同的原因，我得到了相同的错误（NoSuchMethodError）。如果我想访问SAP CRM而不是S/4HANA，是否可以尝试您在回答中指出的第一个选项？嗯，好的。我只是在本地运行了您的pom文件和代码，一经提供（导致报告的NoSuchMethodError）和我建议的更改。由于缺少Neo运行时，这些更改导致了错误，这是意料之中的（因为我在没有任何Neo设置的情况下在本地运行它）。你能再检查一下你的新错误是什么吗？或者更好：找不到什么类/方法？此外，我还更新了我的代码片段，向您展示了如何创建“自己的”目的地，这可能会使测试更容易。非常感谢您的回答。我尝试了您提供的代码片段，代码运行得非常好。我能够将请求发送到OData服务。我非常感谢你和亚历山大花时间帮助我。很高兴听到这个消息！哦，我忘了回答你的第二个问题：我们的目标是与任何OData服务兼容，因此只要你可以检索元数据文件，你就可以使用生成器创建类型化的VDM。
