     public String Data(ModelMap model) throws KeyStoreException, NoSuchAlgorithmException, CertificateException, FileNotFoundException, IOException, KeyManagementException, UnrecoverableKeyException{

        KeyStore keyStore = KeyStore.getInstance(KeyStore.getDefaultType());
        keyStore.load(new FileInputStream("/users/crohitk/Documents/workspace/frr/publicKey1.store"),
                "password".toCharArray());
        SSLConnectionSocketFactory socketFactory = new SSLConnectionSocketFactory(
                new SSLContextBuilder()
                        .loadTrustMaterial(null, new TrustSelfSignedStrategy())
                        .loadKeyMaterial(keyStore, "password".toCharArray()).build());
        HttpClient httpClient = HttpClients.custom().setSSLSocketFactory(socketFactory).build();
        ClientHttpRequestFactory requestFactory = new HttpComponentsClientHttpRequestFactory(
                httpClient);
        RestTemplate restTemplate = new RestTemplate(requestFactory);


        ResponseEntity<String> result = restTemplate.exchange("https://jira.example.com/",  HttpMethod.GET, new HttpEntity<String>(createHeaders("user", "password")), String.class);

        model.addAttribute("message", result);


        return "helloworld";

      }


     HttpHeaders createHeaders( String username, String password ){
        HttpHeaders header =  new HttpHeaders();
        String auth = username + ":" + password;
        byte[] encodedAuth = Base64.encodeBase64(auth.getBytes(Charset.forName("US-ASCII")) );
        String base64Creds = "Basic " + new String( encodedAuth );
        header.add("Authorization", "Basic " + base64Creds);
        return header;

Change encoding credentials of above code to below code in java file there is some error in encoding of above code

HttpHeaders createHeaders(){
    String plainCreds = "user:password";
    byte[] plainCredsBytes = plainCreds.getBytes();
    byte[] base64CredsBytes = Base64.encodeBase64(plainCredsBytes);
    String base64Creds = new String(base64CredsBytes);


    HttpHeaders headers = new HttpHeaders();
    headers.add("Authorization", "Basic " + base64Creds);
    return headers;
}
