目录文件结构

在配置文件下创建下面两个文件

 文件内容

HttpsClientHttpRequestFactory.java

package org.fri.config;

import org.apache.http.ssl.SSLContexts;
import org.apache.http.ssl.TrustStrategy;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.client.SimpleClientHttpRequestFactory;

import javax.net.ssl.HttpsURLConnection;
import javax.net.ssl.SSLContext;
import java.io.IOException;
import java.net.HttpURLConnection;
import java.security.KeyStore;

/**
 * 处理无法发送https 请求问题
 * 忽略 https 校验
 */
@Configuration
public class HttpsClientHttpRequestFactory extends SimpleClientHttpRequestFactory {
    @Override
    protected void prepareConnection(HttpURLConnection connection, String httpMethod) throws IOException {
        try {
            if (connection instanceof HttpsURLConnection) {
                KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType());
                //信任任何链接，忽略对证书的校验
                TrustStrategy trustStrategy = (x509Certificates, s) -> true;
                //自定义sslcontext
                SSLContext ctx = SSLContexts.custom().loadTrustMaterial(trustStore, trustStrategy).build();
                //解决问题
                ((HttpsURLConnection) connection).setSSLSocketFactory(ctx.getSocketFactory());
                //解决No subject alternative names matching IP address xxx.xxx.xxx.xxxx found问题
                ((HttpsURLConnection) connection).setHostnameVerifier((s, sslSession) -> true);
                HttpsURLConnection httpsURLConnection = (HttpsURLConnection) connection;
                super.prepareConnection(httpsURLConnection, httpMethod);
            } else {
                super.prepareConnection(connection, httpMethod);
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

 ResTemplateConfig.java

package org.fri.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.client.RestTemplate;

@Configuration
public class ResTemplateConfig {
    @Bean
    RestTemplate restTemplate() {
        return new RestTemplate(new HttpsClientHttpRequestFactory());
    }
}

配置完成

请求示例

HttpHeaders headers = new HttpHeaders();       
HttpEntity<String> requestEntity = new HttpEntity<>(headers);
ResponseEntity<JSONObject> responseEntity = restTemplate.exchange(reqUri, HttpMethod.GET, requestEntity, JSONObject.class);
if (responseEntity.getStatusCode().equals(HttpStatus.OK)) {
    log.info(responseEntity.getBody().toJSONString());
}

 完结撒花！！！
