我们正在使用Hana Cloud Platform Java应用程序外部的RESTful服务。我们能够通过作为应用程序JEE6配置文件和其他HCP库的一部分提供的Apache HttpClient（v4.1.3）与HCP中的这些目标设置进行交互，应用程序配置为使用JRE 7.
我们正在连接的集成基础架构供应商，最近禁用了TLSv1.0，从那时起我们在尝试连接到REST服务时遇到错误。
这是堆栈跟踪：

我们尝试将JVM参数添加到Java应用程序以强制它使用TLSv1.1或TLSv1.2而不使用TLSv1.0：
-Dhttps.protocols=TLSv1.1,TLSv1.2
设置JVM参数什么也不做，似乎Apache HttpClient库忽略了这个设置。是否有另一种方法可以强制Apache HttpClient（v4.1.3）更新版本的TLS？
答案 0 :(得分：0)
事实证明，可以扩展类org.apache.http.conn.ssl.SSLSocketFactory并使用HttpClient注册它以强制客户端使用特定协议。实际上，您可以使用相同的机制来更改密码，超时等。
添加此附加代码以从HttpDestination创建HttpClient：
private static final String CA_CERTS_PATH = System.getProperties().getProperty("java.home") + File.separator +
"lib" + File.separator + "security" + File.separator + "cacerts";
private HttpClient createHttpClient(HttpDestination httpDestination)
throws DestinationException, KeyStoreException, IOException, CertificateException, NoSuchAlgorithmException, KeyManagementException {
HttpClient httpClient = httpDestination.createHttpClient();
try (FileInputStream fis = new FileInputStream(CA_CERTS_PATH)) {
KeyStore keyStore = KeyStore.getInstance("JKS");
keyStore.load(fis, "changeit".toCharArray());
TrustManagerFactory tmf = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
tmf.init(keyStore);
SSLContext ctx = SSLContext.getInstance("TLS");
ctx.init(null, tmf.getTrustManagers(), new SecureRandom());
// Instantiate the custom SSLSocketFactory
SSLSocketFactory sslSocketFactory = new CustomSSLSocketFactory(
ctx,
SSLSocketFactory.BROWSER_COMPATIBLE_HOSTNAME_VERIFIER,
new String[]{"TLSv1.1", "TLSv1.2"}
);
// Register the https scheme with the custom SSLSocketFactory
Scheme httpsScheme = new Scheme("https", 443, sslSocketFactory);
httpClient.getConnectionManager().getSchemeRegistry().register(httpsScheme);
}
return httpClient;
}
并扩展SSLSocketFactory类：

import org.apache.http.conn.ssl.X509HostnameVerifier;
import org.apache.http.params.HttpParams;
import javax.net.ssl.SSLContext;
