官方代碼如下：

// This file is auto-generated, don't edit it. Thanks.
package com.aliyun.sample;import com.aliyun.tea.*;public class Sample {/*** 使用AK&SK初始化賬號Client* @param accessKeyId* @param accessKeySecret* @return Client* @throws Exception*/public static com.aliyun.dysmsapi20170525.Client createClient(String accessKeyId, String accessKeySecret) throws Exception {com.aliyun.teaopenapi.models.Config config = new com.aliyun.teaopenapi.models.Config()// 必填，您的 AccessKey ID.setAccessKeyId(accessKeyId)// 必填，您的 AccessKey Secret.setAccessKeySecret(accessKeySecret);// Endpoint 請參考 https://api.aliyun.com/product/Dysmsapiconfig.endpoint = "dysmsapi.aliyuncs.com";return new com.aliyun.dysmsapi20170525.Client(config);}public static void main(String[] args_) throws Exception {java.util.List<String> args = java.util.Arrays.asList(args_);// 請確保代碼運行環境設置了環境變量 ALIBABA_CLOUD_ACCESS_KEY_ID 和 ALIBABA_CLOUD_ACCESS_KEY_SECRET。// 工程代碼泄露可能會導致 AccessKey 泄露，并威脅賬號下所有資源的安全性。以下代碼示例使用環境變量獲取 AccessKey 的方式進行調用，僅供參考，建議使用更安全的 STS 方式，更多鑒權訪問方式請參見：https://help.aliyun.com/document_detail/378657.htmlcom.aliyun.dysmsapi20170525.Client client = Sample.createClient(System.getenv("ALIBABA_CLOUD_ACCESS_KEY_ID"), System.getenv("ALIBABA_CLOUD_ACCESS_KEY_SECRET"));com.aliyun.dysmsapi20170525.models.SendSmsRequest sendSmsRequest = new com.aliyun.dysmsapi20170525.models.SendSmsRequest().setSignName("阿里云短信測試").setTemplateCode("SMS_154950909").setPhoneNumbers("15138098888").setTemplateParam("{\"code\":\"1234\"}");com.aliyun.teautil.models.RuntimeOptions runtime = new com.aliyun.teautil.models.RuntimeOptions();try {// 復制代碼運行請自行打印 API 的返回值client.sendSmsWithOptions(sendSmsRequest, runtime);} catch (TeaException error) {// 如有需要，請打印 errorcom.aliyun.teautil.Common.assertAsString(error.message);} catch (Exception _error) {TeaException error = new TeaException(_error.getMessage(), _error);// 如有需要，請打印 errorcom.aliyun.teautil.Common.assertAsString(error.message);}        }
}

上述代碼在使用的時候只需要更改這幾個地方即可。
