在java中获取SSLHandshakeException

Question

从简单的 java 存根调用 https RESTful Web 服务时，我在 Eclipse 中遇到 SSL Hand Shake 错误，但是，在将客户端数字证书导入服务提供商共享的浏览器后，可以从浏览器访问此 URL。出于安全目的隐藏端点 URL。 请帮助我，我是从 Java 客户端使用 https Web 服务的新手。

JAVA 存根如下：

 try {
          URL url = new URL("https://*********************");
             conn = (HttpURLConnection) url.openConnection();
            conn.setRequestMethod("GET");
            conn.setRequestProperty("enctype","multipart/form-data");
            conn.setRequestProperty("Accept", "text/xml");
            System.out.println("Printing Connetion Object "+conn);
        if (conn.getResponseCode() != 200) {
            throw new RuntimeException("Failed : HTTP error code : "
                    + conn.getResponseCode());
        }

        BufferedReader br = new BufferedReader(new InputStreamReader(
            (conn.getInputStream()))); 
        String output;
        System.out.println("Output from Server .... \n");
        while ((output = br.readLine()) != null) {
            System.out.println(output);
        }
        conn.disconnect();
      } catch (MalformedURLException e) {
          System.out.println("MalformedURLException-->"+conn);
        e.printStackTrace();
      } catch (IOException e) {
          System.out.println("IOException-->"+conn);
        e.printStackTrace();

      }

报错如下：

如果导入密钥库不能解决您的问题.. 因为我无法解决它。 然后添加以下代码行。它对我有用。

System.setProperty( "javax.net.ssl.keyStore", "D:\\G2B.p12" );  // The path to the .p12 file
          System.setProperty( "javax.net.ssl.keyStorePassword", "****" );  // The password of the p12 file
          System.setProperty( "javax.net.ssl.keyStoreType", "pkcs12" );  // Default is JKS, we're using PKCS12
