I have googled it with issue. But those are not able to solve my problem.I have an issue with the SSL certificate in my code while calling a rest control.
My control method is:
@CrossOrigin(origins = "")
@RequestMapping(value = "/token", method = RequestMethod.POST, produces = "application/json")
public @ResponseBody TokenModel GetToken(@RequestBody RequestBodyJson requestBodyJson) {
TokenModel response = null;
RestTemplate restTemplate = new RestTemplate();
try {
response = new GenericRestClient<RequestBodyJson, TokenModel>().execute(
new RequestDetails(url, HttpMethod.POST), requestBodyJson, responseHandler,TokenModel.class);
restTemplate.getForEntity(url , TokenModel.class);
} catch (Exception e) {
System.out.println(e.getMessage());
}
return response;
}
Error is:-I/O error on POST request for "": sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target; nested exception is javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
can anyone can help me here?

Thanks guys for your help.
I have solved the problem by
In my POM.XML i have added one dependency
<!-- -->
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
<version>4.5</version>
</dependency>
Then my JAVA code is
@RequestMapping(value = "/gettokens", method = RequestMethod.POST, produces = "application/json")
public @ResponseBody ResponseEntity<TokenModel> GetTokens(@RequestBody RequestBodyJson requestBodyJson)
throws KeyManagementException, NoSuchAlgorithmException, KeyStoreException {
ResponseEntity<TokenModel> response = null;
TrustStrategy acceptingTrustStrategy = (X509Certificate[] chain, String authType) -> true;
SSLContext sslContext = org.apache.http.ssl.SSLContexts.custom()
.loadTrustMaterial(null, acceptingTrustStrategy).build();
SSLConnectionSocketFactory csf = new SSLConnectionSocketFactory(sslContext);
CloseableHttpClient httpClient = HttpClients.custom()
.setSSLSocketFactory(csf).build();
HttpComponentsClientHttpRequestFactory requestFactory = new HttpComponentsClientHttpRequestFactory();
requestFactory.setHttpClient(httpClient);
RestTemplate restTemplate = new RestTemplate(requestFactory);
try {
MultiValueMap<String, String> headers = new LinkedMultiValueMap<String, String>();
Map map = new HashMap<String, String>();
map.put("Content-Type", "application/json");
headers.setAll(map);
HttpEntity<?> _HttpEntityRequestBodyJson = new HttpEntity<>(requestBodyJson, headers);
response= restTemplate.exchange(url, HttpMethod.POST,_HttpEntityRequestBodyJson, new ParameterizedTypeReference<TokenModel>() {});
System.out.println(response.getBody());
} catch (Exception e) {
System.out.println(e.getMessage());
}
return response;
}
