RestTemplate调用Https接口

Posted 2020-12-22 miaoying

本文简单示例 Java 实例化一个可调用 https 请求的 RestTemplate：

public static RestTemplate getRestTemplate() throws KeyStoreException, NoSuchAlgorithmException, KeyManagementException {
        SSLContext sslContext = new SSLContextBuilder().loadTrustMaterial(null, new TrustStrategy() {
            @Override
            public boolean isTrusted(X509Certificate[] arg0, String arg1) throws CertificateException {
                return true;
            }
        }).build();

        SSLConnectionSocketFactory csf = new SSLConnectionSocketFactory(sslContext,
                new String[]{"TLSv1"},
                null,
                NoopHostnameVerifier.INSTANCE);

        CloseableHttpClient httpClient = HttpClients.custom()
                .setSSLSocketFactory(csf)
                .build();

        HttpComponentsClientHttpRequestFactory requestFactory =
                new HttpComponentsClientHttpRequestFactory();

        requestFactory.setHttpClient(httpClient);
        RestTemplate restTemplate = new RestTemplate(requestFactory);
        return restTemplate;
    }
