1.新建工具类
import java.security.KeyManagementException; import java.security.KeyStoreException; import java.security.NoSuchAlgorithmException; import javax.net.ssl.SSLContext; 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; @Configuration public class RestTemplateConfig { @Bean public RestTemplate restTemplate(ClientHttpRequestFactory factory) { return new RestTemplate(factory); } @Bean public ClientHttpRequestFactory simpleClientHttpRequestFactory() { HttpComponentsClientHttpRequestFactory factory = new HttpComponentsClientHttpRequestFactory(); factory.setConnectTimeout(3000); 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; } }2. 实例化并使用
log.info("--------------开始请求"); HttpHeaders headers = new HttpHeaders(); // headers.set("token", tokenStr); headers.setContentType(MediaType.APPLICATION_JSON_UTF8); HttpEntity<String> entity = new HttpEntity<String>(jsonDataStr, headers); RestTemplate restTemplateHttps = new RestTemplate(RestTemplateConfig.generateHttpRequestFactory()); ResponseEntity<String> stringResponseEntity = restTemplateHttps.exchange(url, HttpMethod.POST, entity, String.class); log.info("--------------请求结束"); // 响应状态 String body = stringResponseEntity.getBody(); log.info("获取返回信息:" + body);
