如何在VDM中获取本地化字段的文本？

Question

我正在尝试使用VDM从我们的S / 4HANA云（公共云）中获取业务合作伙伴数据。

        final List<BusinessPartner> businessPartners =
                new DefaultBusinessPartnerService()
                        .getAllBusinessPartner()
                        .select(BusinessPartner.BUSINESS_PARTNER,
                                BusinessPartner.BUSINESS_PARTNER_NAME)
                        .filter(BusinessPartner.BUSINESS_PARTNER_CATEGORY.eq("2"))
                        .orderBy(BusinessPartner.BUSINESS_PARTNER, Order.ASC)
                        .execute();

英文业务伙伴名称显示正确。 但是日语业务伙伴名称显示为?????。

{"BusinessPartner":"80000001","BusinessPartnerName":"Domestic US Customer 1"},
{"BusinessPartner":"80000002","BusinessPartnerName":"?????????????"},
{"BusinessPartner":"90000001","BusinessPartnerName":"Domestic US Supplier 1"},
{"BusinessPartner":"90000002","BusinessPartnerName":"????????"}

您能给我建议如何获取本地化字段的文本吗？

谢谢。

（补充笔记）

我用邮递员手动执行了OData。 在这种情况下，本地化字段以日语显示。

https://myXXXXXX.s4hana.ondemand.com/sap/opu/odata/sap/API_BUSINESS_PARTNER/A_BusinessPartner?$select=BusinessPartner,BusinessPartnerName&$orderby=BusinessPartner&$filter=BusinessPartnerCategory%20eq%20'2'&$format=json&saml2=disabled

输出

    "d": {
        "results": [
            {
                "__metadata": {
                    "id": "https://myXXXXXX.s4hana.ondemand.com:443/sap/opu/odata/sap/API_BUSINESS_PARTNER/A_BusinessPartner('80000001')",

如果您使用的是HttpServlet ，请确保在编写响应之前将HttpServletResponse对象的字符编码设置为UTF-8 ，并将内容类型设置为application/json 。

response.setContentType("application/json");
response.setCharacterEncoding("UTF-8");
