2、@Configuration

public class RestTemplateConfig {

@Bean

public RestTemplate restTemplate() throws KeyStoreException, NoSuchAlgorithmException, KeyManagementException {

TrustStrategy acceptingTrustStrategy = (X509Certificate[] chain, String authType) -> true;

SSLContext sslContext = org.apache.http.ssl.SSLContexts.custom()

.loadTrustMaterial(null, acceptingTrustStrategy)

.build();

SSLConnectionSocketFactory csf = new SSLConnectionSocketFactory(sslContext);

CloseableHttpClient httpClient = HttpClients.custom()

.setSSLSocketFactory(csf)

.build();

HttpComponentsClientHttpRequestFactory requestFactory =

new HttpComponentsClientHttpRequestFactory();

requestFactory.setHttpClient(httpClient);

RestTemplate restTemplate = new RestTemplate(requestFactory);

return restTemplate;

}

}

测试：

public String getData()     {
   //接口地址         String url = "https://free-api.heweather.com/v5/forecast?city=CN101080101&key=5c043b56de9f4371b0c7f8bee8f5b75e";         Map
    
      params = new HashMap<>(); params.put("start_time", "20180824"); params.put("end_time", "20180827"); // RestTemplate restTemplate = new RestTemplate();//此处直接autowire即可，不用new HttpEntity httpEntity = new HttpEntity(params, null); ResponseEntity
     
       request = restTemplate.postForEntity(url, httpEntity, String.class); return request.getBody().toString(); }
