关于springboot:springboot调用https接口

1.springboot我的项目调用https接口

import org.springframework.http.client.SimpleClientHttpRequestFactory;
import org.springframework.stereotype.Component;
import org.springframework.web.client.RestTemplate;

        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    private static class MyCustomSSLSocketFactory extends SSLSocketFactory {

            return socket;
        }
    }
}

2.应用demo

SSLRestTemplate sslRestTemplate = new SSLRestTemplate();
ResponseEntity<JsonObject> exchange = sslRestTemplate.exchange(url, HttpMethod.POST, requestEntity, JsonObject.class);
