如何在 CXF 客户端中使用修补程序方法

Question

我试图使用CXF(3 . 1 . 3版)客户端调用带有补丁方法的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

如何在CXF中使用补丁方法

验证CXF HttpAsyncClient对use.async.http的使用。管道上下文属性

以下是代码片段:

    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); 

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

其他端服务是使用 RestEasy 实现的，看起来就像不遵守 X-HTTP 方法-覆盖标头。

你能帮我找到问题吗？

当我们遇到类似的问题时，我们使用了< code > CloseableHttpAsyncClient ,效果很好。以下是示例代码，供您参考:

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;
