我正在按照下面的教程使用 CAP Java 项目中的 SAP Cloud SDK 来调用 S/4HANA 本地系统的 OData API。与 Cloud SDK Spring 原型项目相比，在 CAP Java 项目中使用 VDM 没有太大区别。
https://developers.sap.com/tutorials/cloudsdk-integrate-cap.html
这是 CAP Java 项目中的一些代码片段。
HttpDestination httpDestination = DestinationAccessor.getDestination("s4x011").asHttp();
List<BusinessPartner> businesspartners = null;
try {
businesspartners = new DefaultBusinessPartnerService().getAllBusinessPartner().execute(httpDestination);
} catch (ODataException e) {
e.printStackTrace();
}
我遇到的问题是在 Business Application Studio 中提供目标“s4x011”来进行本地测试。由于它将通过云连接器连接本地 OData API，我需要提供在 SAP Cloud Foundry 环境中定义的目标名称。
以下博客中描述了一个解决方案。我需要在 .env1 文件中提供“目的地”。例如，
destinations=[{"name":"s4x011", "proxyHost":"http://127.0.0.1", "proxyPort":"8887", "url":"http://s4x011.dest"}]
https://blogs.sap.com/2020/06/02/how-to-reach-on-premise-odata-from-the-business-application-studio/
目的地“s4x011”在 sap 云平台中定义。这是在 SAP Cloud Platform 中定义目标的博客。 https://help.sap.com/viewer/9d1db9835307451daa8c930fbd9ab264/Cloud/en-US/e72930c96b664e3ea4ce5288eb84075f.html
这是我在子账户级别的目标“s4x011”配置。
一切准备就绪后，我使用 mvn 命令启动了我的应用程序。它仍然找不到目的地“s4x011”。
mvn sping-boot:run
这是错误堆栈。

=============更新===============
我在default-env.jsonCAP Java 项目的根文件夹中创建了一个带有目的地的文件夹。然后我无法启动我的应用程序。
{
"destinations": [
{
"name": "s4x011",
"proxyHost": "http://127.0.0.1",
"proxyPort": "8887",
"url": "http://s4x011.dest"
}
]
}
然后我在 default-env.json 中添加了“VCAP_SERVICES”。可以启动应用程序，但仍未找到目的地。
{
"destinations": [
{
"name": "s4x011",
"proxyHost": "http://127.0.0.1",
"proxyPort": "8887",
"url": "http://s4x011.dest"
}
],
"VCAP_SERVICES": {
}
}
