使用RestTemplate发送https请求-忽略ssl证书_resttemplate忽略证书

RestTemplate调用https服务的时候，由于服务方的ssl证书并非正式证书，不被jdk接受，故会报类似：“No subject alternative names matching IP address xxxxxx found”的错误。网上找了一下，处理也比较简单，基本上是配置下：HttpRequestFactory。但找到的内容很多都是需要注入bean，通过@Config等方式配置，这样的话，不是很便利。

以下代码，通过直接调用main函数，处理了RestTemplate，使其忽略SSL证书。

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.http.HttpHeaders;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;public class TestNoSSLRest { static String URL = \"https://192.168.88.70:8443/oauth/oauth2/token?grant_type=authorization_code&code=iDCQAU\"; public static void main(String[] args) throws NoSuchAlgorithmException, KeyStoreException, KeyManagementException { RestTemplate restTemplate = new RestTemplate(generateHttpRequestFactory()); String responseStr = restTemplate.postForObject(URL, initHttpHeaders(), String.class); System.out.println(responseStr); } private static HttpHeaders initHttpHeaders() { HttpHeaders headers = new HttpHeaders(); headers.add(\"Authorization\", \"Basic Soiuawe12asildfSEjasdfewe22\"); return headers; } private 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; }}
