我使用下面链接中描述的 S4SDK 开发了一个 Java 应用程序，并将其部署到 SAP Cloud 平台云代工环境。
然后我使用 POSTMAN 工具访问了该应用程序。首先，我发出了 GET 请求application URL/businesspartners并获取了x-csrf-token. 如博客（上面的链接）中所述，我将其x-csrf-token用于with body 的POST操作。application URL/businesspartners
所以，当我发出一个帖子请求时，它给出了一个错误：405 METHOD NOT ALLOWED
下面是servlet：
@WebServlet("/businesspartners")
public class BusinessPartnerServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
private static final Logger logger = CloudLoggerFactory.getLogger(BusinessPartnerServlet.class);
private static final String CATEGORY_PERSON = "1";
@Override
protected void doGet(final HttpServletRequest request, final HttpServletResponse response)
throws ServletException, IOException {
try {
final List<BusinessPartner> businessPartners =
new DefaultBusinessPartnerService()
.getAllBusinessPartner()
.select(BusinessPartner.BUSINESS_PARTNER,
BusinessPartner.LAST_NAME,
BusinessPartner.FIRST_NAME,
BusinessPartner.IS_MALE,
BusinessPartner.IS_FEMALE,
BusinessPartner.CREATION_DATE)
.filter(BusinessPartner.BUSINESS_PARTNER_CATEGORY.eq(CATEGORY_PERSON))
.orderBy(BusinessPartner.LAST_NAME, Order.ASC)
.execute();
response.setContentType("application/json");
response.getWriter().write(new Gson().toJson(businessPartners));
} catch (final ODataException e) {
logger.error(e.getMessage(), e);
response.setStatus(HttpServletResponse.SC_INTERNAL_SERVER_ERROR);
response.getWriter().write(e.getMessage());
}
}
