Skip SSL certificate verification in Spring Rest Template

How to skip SSL certificate verification while using Spring Rest Template? Configure Rest Template so it uses Http Client to create requests.

Note: If you are familiar with sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target the below should help you.

Http Client

Firstly, import HttpClient (>4.4), to your project


Configure RestTemplate

Configure SSLContext using Http Client’s SSLContexts factory methods:

TrustStrategy acceptingTrustStrategy = (X509Certificate[] chain, String authType) -> true;

SSLContext sslContext = org.apache.http.ssl.SSLContexts.custom()
        .loadTrustMaterial(null, acceptingTrustStrategy)

SSLConnectionSocketFactory csf = new SSLConnectionSocketFactory(sslContext);

CloseableHttpClient httpClient = HttpClients.custom()

HttpComponentsClientHttpRequestFactory requestFactory =
        new HttpComponentsClientHttpRequestFactory();


RestTemplate restTemplate = new RestTemplate(requestFactory);

org.apache.http.ssl.TrustStrategy is used to override standard certificate verification process. In the above example – it always returns true, so the certificate can be trusted without further verification.

The Test

public void opensSSLPage() throws Exception {
    String uri = "https://some-secured-page.com";
    ResponseEntity<String> entity = restTemplate.getForEntity(uri, String.class);

Final Word

The above code helps in certain situations (e.g. testing against servers with self-signed certificates), but it should not be used in production – unless you are 100% sure what you are doing.

I have a question. Why spring restTemplate gives the facility to Bypass SSL certificate validation. If we can by pass then any body can access our rest service.
