配置代理Jersey客户端(Configure proxy to Jersey client)

我想一个代理服务器配置为我的球衣客户端。
我不想配置代理整个应用程序（使用JVM参数如http.proxyHost）和Id'e宁可不使用Apache客户端。
我读到这里 ，有是通过HttpUrlConnectionFactory提供HttpURLConnection类做一种选择，但我找不到任何代码示例。
有谁知道我该怎么办呢？
谢谢！

Answer 1:

随着卢卡的帮助下，我得到了它做：

1. 实施HttpURLConnectionFactory ，并重写方法getHttpURLConnection ，我实现（感谢卢卡）：

    Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress("127.0.0.1", 3128)); return new HttpURLConnection(url, proxy); 

2. 实例泽西客户端之前，创建一个新的URLConnectionClientHandler ，并提供您HttpURLConnectionFactory在其构造。 然后创建一个新的Client ，并提供您ClientHandler在Client的构造。 我的代码：

    URLConnectionClientHandler urlConnectionClientHandler = new URLConnectionClientHandler(new MyHttpURLConnectionFactory()); _client = new Client(urlConnectionClientHandler); 

希望的帮助。

Answer 2:

首先，我创建了这个类

    import com.sun.jersey.client.urlconnection.HttpURLConnectionFactory;
    import java.io.IOException;
    import java.net.HttpURLConnection;
    import java.net.InetSocketAddress;
    import java.net.Proxy;
    import java.net.URL;
    import java.security.KeyManagementException;
import java.security.NoSuchAlgorithmException;
import java.security.SecureRandom;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.net.ssl.HostnameVerifier;
import javax.net.ssl.HttpsURLConnection;
import javax.net.ssl.SSLContext;
import javax.net.ssl.TrustManager;

/**

public class ConnectionFactory implements HttpURLConnectionFactory {

    Proxy proxy;

    String proxyHost;

    Integer proxyPort;

    SSLContext sslContext;

    public ConnectionFactory() {
    }

    public ConnectionFactory(String proxyHost, Integer proxyPort) {
        this.proxyHost = proxyHost;
        this.proxyPort = proxyPort;
    }

    private void initializeProxy() {
        proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress(proxyHost, proxyPort));
    }

    @Override
    public HttpURLConnection getHttpURLConnection(URL url) throws IOException {
        initializeProxy();
        HttpURLConnection con = (HttpURLConnection) url.openConnection(proxy);
        if (con instanceof HttpsURLConnection) {
            System.out.println("The valus is....");
            HttpsURLConnection httpsCon = (HttpsURLConnection) url.openConnection(proxy);
            httpsCon.setHostnameVerifier(getHostnameVerifier());
            httpsCon.setSSLSocketFactory(getSslContext().getSocketFactory());
            return httpsCon;
        } else {
            return con;
        }

    }

    public SSLContext getSslContext() {
        try {
            sslContext = SSLContext.getInstance("SSL");
            sslContext.init(null, new TrustManager[]{new SecureTrustManager()}, new SecureRandom());
        } catch (NoSuchAlgorithmException ex) {
            Logger.getLogger(ConnectionFactory.class.getName()).log(Level.SEVERE, null, ex);
        } catch (KeyManagementException ex) {
            Logger.getLogger(ConnectionFactory.class.getName()).log(Level.SEVERE, null, ex);
        }
        return sslContext;
    }

    private HostnameVerifier getHostnameVerifier() {
        return new HostnameVerifier() {
            @Override
            public boolean verify(String hostname,
                    javax.net.ssl.SSLSession sslSession) {
                return true;
            }
        };
    }

}

后来我也创建一个名为SecureTrustManager另一个类

    import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;
import javax.net.ssl.X509TrustManager;

/**
 *
 * @author Aimable
 */
public class SecureTrustManager implements X509TrustManager {

    @Override
    public void checkClientTrusted(X509Certificate[] arg0, String arg1)
            throws CertificateException {
    }

    @Override
    public void checkServerTrusted(X509Certificate[] arg0, String arg1)
            throws CertificateException {
    }

    @Override
    public X509Certificate[] getAcceptedIssuers() {
        return new X509Certificate[0];
    }

    public boolean isClientTrusted(X509Certificate[] arg0) {
        return true;
    }

    public boolean isServerTrusted(X509Certificate[] arg0) {
        return true;
    }

}

然后创建后该类我打电话像这样的客户端

URLConnectionClientHandler cc = new URLConnectionClientHandler(new ConnectionFactory(webProxy.getWebserviceProxyHost(), webProxy.getWebserviceProxyPort()));
    client = new Client(cc);
    client.setConnectTimeout(2000000);

由代理端口替换webProxy.getWeserviceHost你的ProxyHost和webProxy.getWebserviceProxyPort（）。

这个工作对我来说，它也应该为你工作。 请注意，我用1.8新泽西州，但它也应该适用于新泽西州2

Answer 3:

尝试

Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress(host, port));
conn = new URL(url).openConnection(proxy);
