在这里插入图片描述

        String url = "https://www.baidu.com";
        ResponseEntity<String> res = restTemplate .getForEntity(url, String.class);
        return restTemplate.exchange(url, HttpMethod.GET, null, String.class).getBody();
    }
}

@Configuration
public class RestTemplateConfig {
    @Bean
    public RestTemplate restTemplate() {
        HttpsClientRequestFactory factory = new HttpsClientRequestFactory();
        //单位为ms (部分接口数据量大,读取改为60秒)
        factory.setReadTimeout(60000);
        //单位为ms
        factory.setConnectTimeout(10000);
        return new RestTemplate(factory);
    }
}

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