我需要在IBM Java 1.6 [SR16 FP60]中启用TLS 1.2连接。我尝试通过建立连接
public static void TLS() throws NoSuchAlgorithmException, KeyManagementException, IOException{
System.setProperty("https.protocols", "TLSv1.2");
URL url = new URL("https://jsonplaceholder.typicode.com/posts");
String XML = "<Test></test>"
SSLContext ssl = SSLContext.getInstance("TLSv1.2");
// ctx.init(null, null, null);
ssl.init(null, null, null);
SSLContext.setDefault(ssl);
HttpsURLConnection connection = (HttpsURLConnection) url.openConnection();
connection.setSSLSocketFactory(ssl.getSocketFactory());
connection.setRequestMethod("POST");
connection.setRequestProperty("Content-Type", "application/xml");
connection.setDoOutput(true);
OutputStream os = connection.getOutputStream();
os.write(XML.getBytes());
os.flush();
os.close();
System.out.println(">>>Connection certificate"+connection.getServerCertificates());
System.out.println(">>>Connection"+connection.getContent());
int responseCode = connection.getResponseCode();
System.out.println("POST Response Code : " + responseCode);
System.out.println("POST Response Message : " + connection.getResponseMessage());
if (responseCode == HttpsURLConnection.HTTP_OK) { //success
BufferedReader in = new BufferedReader(new InputStreamReader(
connection.getInputStream()));
String inputLine;
StringBuffer response = new StringBuffer();
while ((inputLine = in .readLine()) != null) {
response.append(inputLine);
} in .close();
System.out.println(response.toString());}
}
建立连接时会引发错误
收到致命警报:握手失败
请告知我们解决此问题的方法。

我猜您正在使用WebSphere 6?您必须升级到7.0.0.23、8.0.0.3或8.5。
