RestTemplate SocketException: Connection Reset using Java 7 but not Java 8
10,712
Issue was that the endpoint required TLSv1.2 and by default Java7 runs TLSv1.1
Configuring the restTemplate to use TLS1.2 solves this issue.
if (restTemplate == null) {
try {
SSLContext context = SSLContext.getInstance("TLSv1.2");
context.init(null, null, null);
CloseableHttpClient httpClient = HttpClientBuilder
.create()
.setSSLContext(context)
.build();
HttpComponentsClientHttpRequestFactory factory = new HttpComponentsClientHttpRequestFactory(httpClient);
restTemplate = new RestTemplate(factory);
} catch (Exception e) {
log.error("could not create SSL Context - cause::: {}", e.getMessage(), e);
throw new CustomException(e);
}
}

When executing an HTTP POST using Spring RestTemplate, I get a java.net.socketException: Connection Reset
However, when I execute the identical code on Java 8 the same code works without issue. I've not found any similar issue related to this.
Can someone point me to anything I might be doing wrong? I've tried even using the command line arguments like -Dhttps.protocols=TLSv1.1,TLSv1.2
Nothing has worked so far. Any assistance would be appreciated
Here is my code:
String xmlResponse = null; if (restTemplate == null) { CloseableHttpClient httpClient = HttpClients.custom().setSSLHostnameVerifier(new NoopHostnameVerifier()).build(); HttpComponentsClientHttpRequestFactory requestFactory = new HttpComponentsClientHttpRequestFactory(); requestFactory.setHttpClient(httpClient); restTemplate = new RestTemplate(requestFactory); } HttpHeaders rqHeaders = new HttpHeaders(); rqHeaders.setContentType(MediaType.TEXT_XML); HttpEntity<String> createAppRequest = new HttpEntity<>(xmlRequest, rqHeaders); ResponseEntity<String> responseEntity = restTemplate.exchange(datasafeURL, HttpMethod.POST, createAppRequest, String.class);Results:
