RestTemplate支持https請求

設置RestTemplate支持https請求

不多說,直接上代碼

@Configuration
public class RestTemplateConfig {

    @Bean
    public RestTemplate restTemplate()
    {
        ClientHttpRequestFactory requestFactory = new HttpComponentsClientHttpRequestFactory(httpClient());
        return new RestTemplate(requestFactory);
    }

    /**
     * Apache HttpClient
     *
     * @return
     * @see [類、類#方法、類#成員]
     */
    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()
                // 服務器返回數據(response)的時間，超時拋出read timeout
                .setSocketTimeout(65000)
                // 連接上服務器(握手成功)的時間，超時拋出connect timeout
                .setConnectTimeout(5000)
                // 從連接池中獲取連接的超時時間，超時拋出ConnectionPoolTimeoutException
                .setConnectionRequestTimeout(1000)
                .build();
        return HttpClientBuilder.create().setDefaultRequestConfig(requestConfig).setConnectionManager(connectionManager).build();
    }
}
