一、基于自定义配置的https

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.beans.factory.annotation.Value;import org.springframework.http.HttpEntity;import org.springframework.http.HttpHeaders;import org.springframework.http.ResponseEntity;import org.springframework.http.client.HttpComponentsClientHttpRequestFactory;import org.springframework.stereotype.Component;import org.springframework.util.LinkedMultiValueMap;import org.springframework.web.client.RestTemplate;import javax.net.ssl.SSLContext;import java.security.KeyManagementException;import java.security.KeyStoreException;import java.security.NoSuchAlgorithmException;import java.util.List;/** * 远程请求的工具类 */@Componentpublic class RestTemplateUtil {    private String remoteIp;    @Value("${remote.ip}")    public void setRemoteIp(String remoteIp) {        this.remoteIp = remoteIp;    }    /***     * 配置https的请求     * @return     * @throws NoSuchAlgorithmException     * @throws KeyManagementException     * @throws KeyStoreException     */    public 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;    }    public String executePost(String url,LinkedMultiValueMap paramsMap) throws NoSuchAlgorithmException, KeyStoreException, KeyManagementException {        String URL=remoteIp+url;        RestTemplate restTemplate = new RestTemplate(generateHttpRequestFactory());        HttpHeaders headers = new HttpHeaders();        HttpEntity<LinkedMultiValueMap<String, Object>> request = new HttpEntity<>(paramsMap, headers);        ResponseEntity<String> response = restTemplate.postForEntity(URL, request , String.class );        String data=response.getBody();        return data;    }}

二、使用HttpUtil实现远程请求，使用的hutool依赖下的工具类

导入依赖

<dependency>   <groupId>cn.hutool</groupId>   <artifactId>hutool-all</artifactId>   <version>4.5.18</version></dependency>

import cn.hutool.http.HttpUtil;Map<String,Object> map=new HashMap<>();map.put("xxx","xx");map.put("xxx","xx");map.put("xxx","xx");map.put("xxx","xx");//远程请求的接口String url=";;HttpUtil.createGet(url).form(map).timeout(1*60*1000).execute().body();
