java - 如何在CXF Client中使用PATCH方法

Question

我尝试使用 CXF(版本 3.1.3)客户端通过 PATCH 方法调用 API。

尝试按照以下线程中指定的步骤进行操作，但无法解决。只获取 URLConnectionHttpConduit 而不是 AsyncHttpConduit

http://cxf.apache.org/docs/asynchronous-client-http-transport.html

How to use PATCH method in CXF

Verifying CXF HttpAsyncClient use of use.async.http.conduit contextual property

这是代码片段:

    Bus bus = BusFactory.getDefaultBus();
    // insist on the async connector to use PATCH.
    bus.setProperty(AsyncHTTPConduit.USE_ASYNC,  
AsyncHTTPConduitFactory.UseAsyncPolicy.ALWAYS);
    WebClient webClient = WebClient.create(request.getRestURL());
   WebClient.getConfig(webClient).getBus().setProperty
     (AsyncHTTPConduit.USE_ASYNC, AsyncHTTPConduitFactory.UseAsyncPolicy.ALWAYS);
   WebClient.getConfig(webClient).getRequestContext()
       .put(AsyncHTTPConduit.USE_ASYNC, AsyncHTTPConduitFactory.
       UseAsyncPolicy.ALWAYS);
    HTTPConduit conduit = (HTTPConduit)WebClient.getConfig(webClient)
                           .getConduit();
    System.out.println(conduit.getClass().getName());

    Response response = webClient.invoke(request.getMethod(), null);
    System.out.println("service response = "+ response); 

我什至尝试在 POST 请求中使用 X-HTTP-Method-Override=PATCH header ，

其他端服务是使用 RestEasy 实现的，看起来好像不遵守 X-HTTP-Method-Override header 。

你能帮我找出问题所在吗？

当我们遇到类似问题时，我们使用了 CloseableHttpAsyncClient 并且它工作正常。以下是供您引用的示例代码:

IOReactorConfig ioReactorConfig = IOReactorConfig.custom().setIoThreadCount(10).build();
ConnectingIOReactor ioReactor = new DefaultConnectingIOReactor(ioReactorConfig);
PoolingNHttpClientConnectionManager cm = new PoolingNHttpClientConnectionManager(ioReactor);
cm.setMaxTotal(100);
cm.setDefaultMaxPerRoute(10);

RequestConfig requestConfig = RequestConfig.custom()
                .setConnectTimeout(30000)
                .setSocketTimeout(30000).build();

CloseableHttpAsyncClient httpclient = HttpAsyncClients.custom()
                .setConnectionManager(cm)
                .setConnectionManagerShared(false)
                .setDefaultRequestConfig(requestConfig)
                .build();
httpclient.start();

HttpPatch httpReq = new HttpPatch(url);
StringEntity entity = new StringEntity(json);
httpReq.setEntity(entity);

Future<HttpResponse> future = httpclient.execute(httpReq, context, null);
HttpResponse httpResponse = future.get();
HttpEntity responseEntity = httpResponse.getEntity();
String responseText = responseEntity != null ? EntityUtils.toString(responseEntity) : null;
