本文介绍了一种配置HttpClient以支持TLSv1.2的方法，通过创建SSLContext和SSLConnectionSocketFactory，注册到连接管理器中，确保HTTPS请求的安全性。

这个错误可以使用以下方法配置HttpClient来解决：

SSLContext sslContext = SSLContext.getDefault();
SSLConnectionSocketFactory sslConnectionFactory = new SSLConnectionSocketFactory(
		    		sslContext,
		    		new String[]{"TLSv1.2"},
		    		null,
		    		NoopHostnameVerifier.INSTANCE);
Registry<ConnectionSocketFactory> registry = RegistryBuilder.<ConnectionSocketFactory>create()
					.register("https", sslConnectionFactory)
					.register("http", PlainConnectionSocketFactory.INSTANCE)
					.build();
HttpClientConnectionManager ccm = new BasicHttpClientConnectionManager(registry);
CloseableHttpClient httpClient = HttpClientBuilder.create()
			          .setSSLSocketFactory(sslConnectionFactory)
			          .setConnectionManager(ccm).build();
