spring boot http client ssl 체크 패스하기

내부 테스트서버나 로컬에서 ssl 통신을 할때 유용하다.

httpClientConfig.java

@Configuration
public class HttpClientConfig {

    @Bean
    public RestTemplate restTemplate()
            throws KeyStoreException, NoSuchAlgorithmException, KeyManagementException {
        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);
        return restTemplate;
    }
}

생성후 본문에

@Autowire
HttpClientConfig httpClientConfig<
URI uri = URI.create(Url+ "/api/articles");
String responseString = httpClientConfig.getForObject(uri, String.class);
