如何创建具有不同SSL客户端身份验证证书的Apache HttpClients池

KeyStore keyStore = KeyStore.getInstance("PKCS12");
keyStore.load(new FileInputStream("client.p12"), "password".toCharArray());

SSLContext sslContext = SSLContexts.custom()
        .loadKeyMaterial(keyStore, "password".toCharArray())
        .build();

SSLConnectionSocketFactory sslSocketFactory = new SSLConnectionSocketFactory(sslContext,
        new String[]{"TLSv1.2"}, null,
        SSLConnectionSocketFactory.getDefaultHostnameVerifier());

Registry<ConnectionSocketFactory> socketFactoryRegistry = RegistryBuilder.<ConnectionSocketFactory>create()
        .register("https", sslSocketFactory)
        .build();

PoolingHttpClientConnectionManager connectionManager = new PoolingHttpClientConnectionManager(socketFactoryRegistry);
connectionManager.setMaxTotal(100);
connectionManager.setDefaultMaxPerRoute(10);

CloseableHttpClient httpClient = HttpClients.custom()
        .setConnectionManager(connectionManager)
        .build();

HttpGet httpGet = new HttpGet("https://api.example.com");
CloseableHttpResponse response = httpClient.execute(httpGet);
