##### 设置RestTemplate支持https请求 #####

**不多说,直接上代码**

@Configuration
    public class RestTemplateConfig {
    
        @Bean
        public RestTemplate restTemplate()
        {
            ClientHttpRequestFactory requestFactory = new HttpComponentsClientHttpRequestFactory(httpClient());
            return new RestTemplate(requestFactory);
        }
    
        /**
         * Apache HttpClient
         *
         * @return
         * @see [类、类#方法、类#成员]
         */
        private HttpClient httpClient()
        {
            // 支持HTTP、HTTPS
            Registry<ConnectionSocketFactory> registry = RegistryBuilder.<ConnectionSocketFactory> create()
                    .register("http", PlainConnectionSocketFactory.getSocketFactory())
                    .register("https", SSLConnectionSocketFactory.getSocketFactory())
                    .build();
            PoolingHttpClientConnectionManager connectionManager = new PoolingHttpClientConnectionManager(registry);
            connectionManager.setMaxTotal(200);
            connectionManager.setDefaultMaxPerRoute(100);
            connectionManager.setValidateAfterInactivity(2000);
            RequestConfig requestConfig = RequestConfig.custom()
                    // 服务器返回数据(response)的时间，超时抛出read timeout
                    .setSocketTimeout(65000)
                    // 连接上服务器(握手成功)的时间，超时抛出connect timeout
                    .setConnectTimeout(5000)
                    // 从连接池中获取连接的超时时间，超时抛出ConnectionPoolTimeoutException
                    .setConnectionRequestTimeout(1000)
                    .build();
            return HttpClientBuilder.create().setDefaultRequestConfig(requestConfig).setConnectionManager(connectionManager).build();
        }
    }
