SSLv3协议、TLSv1.2协议配置不对导致javax.ws.rs.ProcessingException: java.net.SocketException: Connection reset

SSl：Secure Sockets Layer 安全套接层

TLS:Transport Layer Security传输层安全

是为网络通信提供安全及数据完整性的一种安全协议。TLS与SSL在传输层对网络连接进行加密。(见百度)

场景描述：将公司请求第三方公司的接口协议由http改成https后，出现了请求套接字异常的情况，第三方公司也收不到具体的请求，具体异常如下,

实现http协议的代码为：

 import java.security.SecureRandom;

 import java.security.cert.X509Certificate;

 import javax.net.ssl.HostnameVerifier;

 import javax.net.ssl.SSLContext;

 import javax.net.ssl.SSLSession;

 import javax.net.ssl.TrustManager;

 import javax.net.ssl.X509TrustManager;

 import javax.ws.rs.client.Client;

 import javax.ws.rs.client.ClientBuilder;

 import org.apache.commons.logging.Log;

 import org.apache.commons.logging.LogFactory;

 public class ClientUtil {

     private static Log log = LogFactory.getLog(ClientUtil.class);

     private static SSLContext sslContext = null;

     private static HostnameVerifier hv = null;

     public static Client sslClient = null;

     public static Client client = null;

     static{

         client = ClientBuilder.newClient();

         try {

             sslContext = SSLContext.getInstance("SSLv3");

             sslContext.init(null, new TrustManager[] { new X509TrustManager() {

                 public X509Certificate[] getAcceptedIssuers() {

                     return new X509Certificate[0];

                 }

                 public void checkClientTrusted(X509Certificate[] certs, String authType) {

                 }

                 public void checkServerTrusted(X509Certificate[] certs, String authType) {

                 }

             } }, new SecureRandom());

         } catch (Exception e) {

             log.error("SSL失败", e);

         }

         hv = new HostnameVerifier() {

             public boolean verify( String arg0, SSLSession arg1 ) { return true; }

         };

         sslClient = ClientBuilder.newBuilder().hostnameVerifier(hv).sslContext(sslContext).build();

     }

 }

调用ClientUtil类的代码

         url = url + "?data=" + URLEncoder.encode(jsonObject.toJSONString(), "UTF-8");

         log.info("银联请求: type: " + transType + ", URL:" + url);

         Response response = ClientUtil.client.
                 .target(url)

                 .request()

                 .get();

这里的代码写死了只能用SSLv3安全协议，一运行的时候就报连接错误。可是，同样的请求放到google浏览器上请求就可以通过。

把请求复制到google浏览器请求栏，按F12,点击enter键，查看Security菜单栏输出的网页内容，发现这个请求接受TLS1.2安全协议

为了不影响其它类使用SSL协议，对这个类进行重写。重写后类，新增了获取制定安全协议的方法，支持指定安全协议的请求。

 import java.security.SecureRandom;

 import java.security.cert.X509Certificate;

 import javax.net.ssl.HostnameVerifier;

 import javax.net.ssl.SSLContext;

 import javax.net.ssl.SSLSession;

 import javax.net.ssl.TrustManager;

 import javax.net.ssl.X509TrustManager;

 import javax.ws.rs.client.Client;

 import javax.ws.rs.client.ClientBuilder;

 import org.apache.commons.logging.Log;

 import org.apache.commons.logging.LogFactory;

 public class ClientUtil {

     private static Log log = LogFactory.getLog(ClientUtil.class);

     private static SSLContext sslContext = null;

     private static HostnameVerifier hv = null;

     public static Client sslClient = null;

     public static Client client = null;

     private static TrustManager simpleTrust=null;

     static{

         client = ClientBuilder.newClient();

         try {

             sslContext = SSLContext.getInstance("SSLv3");

             simpleTrust=new X509TrustManager() {

                 public X509Certificate[] getAcceptedIssuers() {

                     return new X509Certificate[0];

                 }

                 public void checkClientTrusted(X509Certificate[] certs, String authType) {

                 }

                 public void checkServerTrusted(X509Certificate[] certs, String authType) {

                 }

             };

             sslContext.init(null, new TrustManager[] { simpleTrust}, new SecureRandom());

         } catch (Exception e) {

             log.error("SSL失败", e);

         }

         hv = new HostnameVerifier() {

             public boolean verify( String arg0, SSLSession arg1 ) { return true; }

         };

         sslClient = ClientBuilder.newBuilder().hostnameVerifier(hv).sslContext(sslContext).build();

     }

     public static Client getSslClient(String protocol)

     {

         try {

             SSLContext sslContextTmp= SSLContext.getInstance(protocol);

             sslContextTmp.init(null, new TrustManager[] { simpleTrust}, new SecureRandom());

             return ClientBuilder.newBuilder().hostnameVerifier(hv).sslContext(sslContextTmp).build();

         }

         catch (Exception ex)

         {

             return ClientBuilder.newBuilder().hostnameVerifier(hv).sslContext(sslContext).build();

         }

     }

 }

改正后的调用方法

         url = url + "?data=" + URLEncoder.encode(jsonObject.toJSONString(), "UTF-8");

         Response response = ClientUtil.getSslClient("TLSv1.2")

                 .target(url)

                 .request()

                 .get();

说明：不同第三方公司支持https协议的时候可以用不同安全协议，对于不同的情况要予以考虑。
