开机自检操作失败，错误405不允许使用方法 [英] POST Operation is failing with an error 405 Method not allowed
本文介绍了开机自检操作失败，错误405不允许使用方法的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我按照下面的链接中所述使用S4SDK开发了Java应用程序，并将其部署到SAP Cloud平台云铸造环境.
I developed a Java application using the S4SDK as described in the link below and deployed it to the SAP Cloud platform cloud foundry environment.
Then I accessed the application using POSTMAN tool. First, I made a GET request for application URL/businesspartners and fetched x-csrf-token. I used this x-csrf-token for POST operation for application URL/businesspartners with body as explained in the blog( above link).
因此，当我发出发布请求时，出现了错误:405 METHOD NOT ALLOWED
So, when I make a post request, it gave an error: 405 METHOD NOT ALLOWED
下面是servlet:
Below is the 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());
}
}
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
final String firstname = request.getParameter("firstname");
final String lastname = request.getParameter("lastname");
final String country = request.getParameter("country");
final String city = request.getParameter("city");
final String email = request.getParameter("email");
//do consistency checks here...
final AddressEmailAddress emailAddress = AddressEmailAddress.builder()
.emailAddress(email)
.build();
final BusinessPartnerAddress businessPartnerAddress = BusinessPartnerAddress.builder()
.country(country)
.cityName(city)
.toEmailAddress(Lists.newArrayList(emailAddress))
.build();
final BusinessPartnerRole businessPartnerRole = BusinessPartnerRole.builder()
.businessPartnerRole("FLCU01")
.build();
final BusinessPartner businessPartner = BusinessPartner.builder()
.firstName(firstname)
.lastName(lastname)
.businessPartnerCategory("1")
.correspondenceLanguage("EN")
.toBusinessPartnerAddress(Lists.newArrayList(businessPartnerAddress))
.toBusinessPartnerRole(Lists.newArrayList(businessPartnerRole))
.build();
String responseBody;
try {
final BusinessPartner storedBusinessPartner = new StoreBusinessPartnerCommand(new ErpConfigContext(), new DefaultBusinessPartnerService(), businessPartner).execute();
responseBody = new Gson().toJson(storedBusinessPartner);
response.setStatus(HttpServletResponse.SC_CREATED);
} catch(final HystrixBadRequestException e) {
responseBody = e.getMessage();
response.setStatus(HttpServletResponse.SC_BAD_REQUEST);
logger.error(e.getMessage(), e);
}
response.setContentType("application/json");
response.getOutputStream().print(responseBody);
}
}
这是我的web.xml文件.
And here my web.xml file.
<?xml version="1.0" encoding="UTF-8"?>
<session-config>
<session-timeout>20</session-timeout>
</session-config>

有人可以帮我吗?
推荐答案
您是否检查过servlet正确实现了doPost方法?关于SO的以下问题对此似乎很好:针对POST请求的Java Servlet返回错误405(不允许使用方法).
Have you checked that your servlet implements the doPost method correctly? The following question on SO seems quite good on this: Java Servlet return error 405 (Method Not Allowed) for POST request.
这篇关于开机自检操作失败，错误405不允许使用方法的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
