最近在工作中需要用到cxf为印度某家公司提供的api去创建一个client，这样我们公司内部可以直接依赖client去调用那些api。做的过程中遭遇了好多坑，主要问题是自己能力不够... 网上有很多关于这方面的文章，但是因为我区分不到他们用的是SOAP，还是用的REST，所以导致了一些问题。

我们要调用的api是REST的，所以实现的时候需要用到JAXRSClientFactory去创建client，我在网上看到的很多代码都是用JaxWsProxyFactoryBean来创建client的，经测试，JaxWsProxyFactoryBean是用来为SOAP协议的，而非REST。

JAXRSClientFactory 和 JaxWsProxyFactoryBean 这两个类的差别就在这里。

已为REST api 创建client为例：还需设置网络代理去访问 fyi~

OrderApi.java 是一个接口，里面设置了patch delete post 方法：

@POST
@Path("/orders")
@Consumes({ MediaType.APPLICATION_JSON })
@Produces({ MediaType.APPLICATION_JSON })
public PostResponse postOrders(PostOrdersRequest postOrdersRequest);
@PATCH
@Path("/orders")
@Consumes({ MediaType.APPLICATION_JSON })
@Produces({ MediaType.APPLICATION_JSON })
public PatchResponse placeOrders(@NotEmpty @RequestBody PatchOrderRequest patchOrderRequest);
@DELETE
@Path("/orders/{OrderIds}")
@Consumes({ MediaType.APPLICATION_JSON })
@Produces({ MediaType.APPLICATION_JSON })
public GetOrderResponse deleteOrders(@QueryParam(value = "AccountKey") String accountKey, @PathParam(value = "OrderIds") String orderIds)

configure 类：
List<Object> providers = new ArrayList<Object>();
providers.add(new JacksonJaxbJsonProvider(objectMapper, DEFAULT_ANNOTATIONS));

// 用JAXRSClientFactory去为OrderApi设置代理类

OrderApi orderApiProxy = JAXRSClientFactory.create(saxoOrderApi, OrderApi.class, providers);
Client client = WebClient.client(orderApiProxy);
ClientConfiguration config = WebClient.getConfig(client);
HTTPConduit httpConduit = config.getHttpConduit();
HTTPClientPolicy httpClientPolicy = new HTTPClientPolicy();
httpClientPolicy.setProxyServer(proxyServer);
httpClientPolicy.setProxyServerPort(proxyPort);
httpConduit.setClient(httpClientPolicy);
ProxyAuthorizationPolicy proxyAuthorizationPolicy = new ProxyAuthorizationPolicy();
proxyAuthorizationPolicy.setUserName(username);
proxyAuthorizationPolicy.setPassword(password);
httpConduit.setProxyAuthorization(proxyAuthorizationPolicy);
TLSClientParameters tlsClientParameters = new TLSClientParameters();
tlsClientParameters.setDisableCNCheck(true);
//创建DumbX509TrustManager去忽略证书：DumbX509TrustManager类继承自 X509TrustManager

tlsClientParameters.setTrustManagers(new TrustManager[] { new

      DumbX509TrustManager() });
httpConduit.setTlsClientParameters(tlsClientParameters);
AuthorizationPolicy authorizationPolicy = new AuthorizationPolicy();
authorizationPolicy.setAuthorizationType("Bearer");
authorizationPolicy.setAuthorization(bearerToken);
httpConduit.setAuthorization(authorizationPolicy);
config.getInInterceptors().add(new LoggingInInterceptor());
config.getOutInterceptors().add(new LoggingOutInterceptor());
