【Java】 如何使用RestTemplate发送HTTPS请求（忽略证书）

1.RestTemplate默认是不支持HTTPS请求的，那么如果想使用RestTemplate发送一个HTTPS的请求 ，就需要对证书进行处理，这里记录一下一个可行的方法。

 

2.导包

import org.apache.http.conn.ssl.NoopHostnameVerifier;
import org.apache.http.conn.ssl.SSLConnectionSocketFactory;
import org.apache.http.conn.ssl.TrustStrategy;
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;

 

3.Maven

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

 

4.代码实现

        try {
            TrustStrategy acceptingTrustStrategy = (chain, authType) -> true;
            SSLContext sslContext = SSLContexts.custom().loadTrustMaterial(null, acceptingTrustStrategy).build();
            SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(sslContext, NoopHostnameVerifier.INSTANCE);

            HttpClientBuilder clientBuilder = HttpClients.custom();

            CloseableHttpClient httpClient = clientBuilder.setSSLSocketFactory(sslsf).build();

            HttpComponentsClientHttpRequestFactory requestFactory = new HttpComponentsClientHttpRequestFactory();
            requestFactory.setHttpClient(httpClient);

            this.restTemplate = new RestTemplate(requestFactory);
        } catch (Exception e) {
            e.printStackTrace();
        }
