我正在使用充气城堡罐来获取TLS1.2实例，但出现以下异常： >
java.security.NoSuchAlgorithmException: no such algorithm: TLS1.2 for provider BCJSSE
at sun.security.jca.GetInstance.getService(GetInstance.java:157)

下面是代码：
`
Security.addProvider(new BouncyCastleJsseProvider());
SSLContext context = SSLContext.getInstance("TLS1.2", Security.getProvider("BCJSSE"));
context.init(null, null, null);
CloseableHttpClient httpClient = HttpClientBuilder.create().setSSLContext(context).build();
HttpComponentsClientHttpRequestFactory factory = new HttpComponentsClientHttpRequestFactory(httpClient);
restTemplate = new RestTemplate(factory);
`
我们需要调用具有TLSv1.2的Web服务，并且我们的服务器具有较低的TLS版本，因此握手失败。 （JDK：v1.6，JARS：bcprov-jdk15on-160，bctls-jdk15on-160）。 如果我做错了什么，请有人帮我或举个例子。
