我正在关注https://blogs.sap.com/2017/05/21/step-4-with-sap-s4hana-cloud-sdk-calling-an-odata-service/comment-page-上的 OData 教程1/当我尝试使用DefaultBusinessPartnerService.
相关的代码是：
DefaultBusinessPartnerService businessPartnerService = new DefaultBusinessPartnerService();
System.err.println("criated default business partner");
List<BusinessPartner> partners = businessPartnerService
.getAllBusinessPartner()
.select(BusinessPartner.BUSINESS_PARTNER,
BusinessPartner.LAST_NAME,
BusinessPartner.FIRST_NAME)
//.filter(BusinessPartner.BUSINESS_PARTNER_CATEGORY.eq(CATEGORY_VENDOR))
.orderBy(BusinessPartner.LAST_NAME, Order.ASC)
.execute(new ErpEndpoint(new ErpConfigContext()));
response.setContentType("application/json");
response.getWriter().write(new Gson().toJson(partners));
我的ErpQueryEndpoint配置如下：
#Mon May 14 15:27:09 BRT 2018
URL=https\://host\:port
Name=ErpQueryEndpoint
TrustAll=TRUE
Type=HTTP
Password=Password
Authentication=BasicAuthentication
User=Username
其中host、port和已替换为正确的值Username。Password
当我查询时，http://localhost:8080/s4integration-application/businesspartners我收到以下错误：
The endpoint responded with HTTP error code 403.
No service found for namespace , name API_BUSINESS_PARTNER, version 0001

}
SAP 系统上似乎没有配置端点（它是 S/4 Hana 系统）。我不确定是否必须URL在主机和端口之外添加其他内容，或者是否必须在 SAP 系统上完成一些其他配置。
