java – 通过代理绕过请求不支持jaxws rs api

我正在向外部流服务器发出http请求;因为我正在使用jaxws-rs-api.

我能够成功地提出请求并做出回应.但是当我尝试通过代理发出请求时,它不会通过代理(即使没有验证代理主机,如果我给了一些错误的IP也会拨打电话).

这是我试过的.

public class ClientCall {
private static final String BOUNDARY = "\r\n";

    public void makeCall() {

        //passing by passing apache connectors as an input to client config 
        // It is giving runtime error; versioning error, it is supportable for jdk8 it seems
        //In my case, I am using JDK7

        /*
         *  ClientConfig clientConfig = new ClientConfig();
         *  clientConfig.connectorProvider(new ApacheConnectorProvider());
         *  client.property(ClientProperties.PROXY_URI, "https://123.123.123.123"); 
         */


        ClientConfig clientConfig = new ClientConfig();
        clientConfig.connectorProvider(new HttpUrlConnectorProvider());
        clientConfig.property(ClientProperties.PROXY_URI, "https://123.123.123.123:8080"); 
        Client client = ClientBuilder.newClient().register(BasicAuthentication.class);

        //passing as inline command line params

        /*
         * System.setProperty ("http.proxyHost", "10.1.224.60");
         * System.setProperty ("http.proxyPort", "8080");
        */

        WebTarget target = client.target("https://external/stream/v1/");
        Builder request = target.request();
        Response response = request.get();
        System.out.println("Result " +response.getStatus());

        final ChunkedInput<String> chunkedInput = response.readEntity(new GenericType<ChunkedInput<String>>() {
        });
        chunkedInput.setParser(ChunkedInput.createParser(BOUNDARY));
        String chunk =null;
        while ((chunk = chunkedInput.read()) != null) {
            System.out.println(chunk);
        }
    }



    public static void main(String[] args) {
        ClientCall client = new ClientCall();
        client.makeCall();
    }
}

就我而言,我没有选择Java8的选项.如果任何库支持JDK7,请建议我.

我为此包含的依赖关系：

commons-collections-4-1,javax-servlet-api-2-5,log4j,slf4j-api-1-7-5,slf4j-log4j12-1-7-5,spring-framework-4-3-0,commons-logging-1-1,commons-configuration,commons-lang,jackson-core-asl-1-9-10,jackson-mapper-asl-1-9-10,spring-context-support-4-3-0,gson-2-8-2,httpcore-4-4-1,httpasyncclient-4-0-1,httpcore-nio-4-4-6,jackson-core-2-8-4,jackson-annotations-2-8-4,jackson-databind-2-8-4,httpclient-4-4-1,httpcore-4-4-1

解决方法:

ClientBuilder不使用变量clientConfig.
我建议你使用以下方法实例化你的JAXRS客户端：

Client client = ClientBuilder.newBuilder()
       .withConfig(clientConfig)
       .register(...)
       .build();
