springboot restTemplate https請求 忽略ssl證書

配置文件RestTemplateConfig

import org.apache.http.conn.ssl.NoopHostnameVerifier; import org.apache.http.conn.ssl.SSLConnectionSocketFactory; import org.apache.http.impl.client.CloseableHttpClient; import org.apache.http.impl.client.HttpClientBuilder; import org.apache.http.impl.client.HttpClients; import org.apache.http.ssl.SSLContexts; import org.apache.http.ssl.TrustStrategy; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.http.client.ClientHttpRequestFactory; import org.springframework.http.client.HttpComponentsClientHttpRequestFactory; import org.springframework.web.client.RestTemplate; import javax.net.ssl.SSLContext; import java.security.KeyManagementException; import java.security.KeyStoreException; import java.security.NoSuchAlgorithmException; @Configuration public class RestTemplateConfig { @Bean public RestTemplate restTemplate(ClientHttpRequestFactory factory){ return new RestTemplate(factory); } @Bean public ClientHttpRequestFactory simpleClientHttpRequestFactory(){ HttpComponentsClientHttpRequestFactory factory = new HttpComponentsClientHttpRequestFactory(); factory.setConnectTimeout(15000); factory.setReadTimeout(5000); return factory; } public static HttpComponentsClientHttpRequestFactory generateHttpRequestFactory() throws NoSuchAlgorithmException, KeyManagementException, KeyStoreException { TrustStrategy acceptingTrustStrategy = (x509Certificates, authType) -> true; SSLContext sslContext = SSLContexts.custom().loadTrustMaterial(null, acceptingTrustStrategy).build(); SSLConnectionSocketFactory connectionSocketFactory = new SSLConnectionSocketFactory(sslContext, new NoopHostnameVerifier()); HttpClientBuilder httpClientBuilder = HttpClients.custom(); httpClientBuilder.setSSLSocketFactory(connectionSocketFactory); CloseableHttpClient httpClient = httpClientBuilder.build(); HttpComponentsClientHttpRequestFactory factory = new HttpComponentsClientHttpRequestFactory(); factory.setHttpClient(httpClient); return factory; } } 

發起請求

與http請求不同的是，https使用restTemplate的時候需要手動創建對象，並傳入參數。而http直接用Autowired注入restTemplate對象就可以直接使用。

String url = "https://xxxx"; RestTemplate restTemplateHttps = new RestTemplate(RestTemplateConfig.generateHttpRequestFactory()); ResponseEntity<String> results = restTemplateHttps.exchange(url, HttpMethod.GET, entity(), String.class); JSONObject json = JSON.parseObject(results.getBody()); System.out.println(json);
