springboot restTemplate https请求 忽略ssl证书

配置文件RestTemplateConfig

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.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 javax.net.ssl.SSLContext;
import java.security.KeyManagementException;
import java.security.KeyStoreException;
import java.security.NoSuchAlgorithmException;

@Configuration
public class RestTemplateConfig {

    @Bean
    public RestTemplate restTemplate(ClientHttpRequestFactory factory){
        return new RestTemplate(factory);
    }

    @Bean
    public ClientHttpRequestFactory simpleClientHttpRequestFactory(){
        HttpComponentsClientHttpRequestFactory factory = new HttpComponentsClientHttpRequestFactory();
        factory.setConnectTimeout(15000);
        factory.setReadTimeout(5000);
        return factory;
    }

    public 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;
    }
}

发起请求

与http请求不同的是，https使用restTemplate的时候需要手动创建对象，并传入参数。而http直接用Autowired注入restTemplate对象就可以直接使用。

String url = "https://xxxx";
RestTemplate restTemplateHttps = new RestTemplate(RestTemplateConfig.generateHttpRequestFactory());
ResponseEntity<String> results = restTemplateHttps.exchange(url, HttpMethod.GET, entity(), String.class);
JSONObject json = JSON.parseObject(results.getBody());
System.out.println(json);
