客户端想通过http就访问https的接口，可以配置restample跳过证书校验。注意，这种方式不安全，只能用在测试环境。

1.maven依赖

       <dependency><groupId>org.apache.httpcomponents</groupId><artifactId>httpclient</artifactId><version>4.5.14</version></dependency>

2. resTemplate 配置

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 org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.ssl.SSLContextBuilder;
import org.apache.http.conn.ssl.NoopHostnameVerifier;/*** RestTemplate配置*/
@Configuration
public class RestConfig {@Beanpublic RestTemplate restTemplate(ClientHttpRequestFactory factory) {return new RestTemplate(factory);}@Beanpublic ClientHttpRequestFactory simpleClientHttpRequestFactory() {try {// 创建SSLContextSSLContextBuilder builder = new SSLContextBuilder();builder.loadTrustMaterial(null, (certificate, authType) -> true);// 设置HttpClientBuilder以使用SSLHttpClientBuilder httpClientBuilder = HttpClientBuilder.create();httpClientBuilder.setSslcontext(builder.build());httpClientBuilder.setSSLHostnameVerifier(NoopHostnameVerifier.INSTANCE);// 创建HttpComponentsClientHttpRequestFactoryHttpComponentsClientHttpRequestFactory requestFactory = new HttpComponentsClientHttpRequestFactory();requestFactory.setHttpClient(httpClientBuilder.build());return requestFactory;} catch (Exception e) {e.printStackTrace();}return null;}
}
