支持 "PATCH" 动词 - WSHttpHandler handleExchange 给出警告:无法处理 HTTP 方法:PATCH

Supporting the "PATCH" verb - WSHttpHandler handleExchange gives WARNING: Cannot handle HTTP method: PATCH

我创建了一个 class,它使用 javax.xml.ws.Endpoint 创建一个 REST 端点:

@WebServiceProvider
@ServiceMode(value = javax.xml.ws.Service.Mode.MESSAGE)
@BindingType(value = HTTPBinding.HTTP_BINDING)
public class SpecificRestAPI implements Provider<Source>
{
    // arg 0: url including port, e.g. "http://localhost:9902/specificrestapi"
    public static void main(String[] args)
    {
        String url = args[0];
        // Start
        Endpoint.publish(url, new SpecificRestAPI());       
    }

    @Resource
    private WebServiceContext wsContext;


    @Override
       public Source invoke(Source request)
       {
          if (wsContext == null)
             throw new RuntimeException("dependency injection failed on wsContext");
          MessageContext msgContext = wsContext.getMessageContext();
          switch (((String) msgContext.get(MessageContext.HTTP_REQUEST_METHOD)).toUpperCase().trim())
          {
             case "DELETE": 
                 return processDelete(msgContext);
             case "PATCH" :
                 return processPatch(msgContext);
'etc...

问题是,当我在 Eclipse 中 运行 这个应用程序并使用 curlPATCH 使用以下命令向它发出请求时:

curl -i -X PATCH http://localhost:9902/specificrestapi?do=action

我在 Eclipse 控制台中收到以下警告:

Jul 30, 2019 3:39:15 PM com.sun.xml.internal.ws.transport.http.server.WSHttpHandler handleExchange WARNING: Cannot handle HTTP method: PATCH

以及对我的 curl 请求的以下响应:

curl: (52) Empty reply from server

查看 here,在 WSHTTPHandler class 中,我可以看出问题出在哪里:

    private void handleExchange(HttpExchange msg) throws IOException {
    WSHTTPConnection con = new ServerConnectionImpl(adapter,msg);
    try {
        if (fineTraceEnabled) {
            LOGGER.log(Level.FINE, "Received HTTP request:{0}", msg.getRequestURI());
        }
        String method = msg.getRequestMethod();
        ' THIS IS THE PROBLEM - IT DOESN'T KNOW ABOUT PATCH!
        if(method.equals(GET_METHOD) || method.equals(POST_METHOD) || method.equals(HEAD_METHOD)
        || method.equals(PUT_METHOD) || method.equals(DELETE_METHOD)) {
            adapter.handle(con);
        } else {
            if (LOGGER.isLoggable(Level.WARNING)) {
                LOGGER.warning(HttpserverMessages.UNEXPECTED_HTTP_METHOD(method));
            }
        }
    } finally {
        msg.close();
    }
}

那么,我有哪些选择? a) 我可以用我自己的自定义 class 替换 WSHTTPHandler 吗?如果是这样,我如何告诉 Endpoint 我想使用它? 或 b) 是否有 WSHttpHandler 的更新版本、更现代的替代方法或创建我可以使用的 web 服务的不同方法?

此处不支持

PATCH - 应改用其他处理程序。
