我最后调试出的问题是secret错误，没有更新。

调试步骤

一、用官方Api调试测试签名、模板是否可用

二、把代码复制到本地，测试 accessKeyId、secret是否可用

package com.zyark.beautiful.shop.modules.generator.common;
import com.aliyuncs.CommonRequest;
import com.aliyuncs.CommonResponse;
import com.aliyuncs.DefaultAcsClient;
import com.aliyuncs.IAcsClient;
import com.aliyuncs.exceptions.ClientException;
import com.aliyuncs.exceptions.ServerException;
import com.aliyuncs.http.MethodType;
import com.aliyuncs.profile.DefaultProfile;


public static void main(String[] args) {
        DefaultProfile profile = DefaultProfile.getProfile("cn-hangzhou", "************************", "***************************");
        IAcsClient client = new DefaultAcsClient(profile);

        CommonRequest request = new CommonRequest();
        request.setMethod(MethodType.POST);
        request.setDomain("dysmsapi.aliyuncs.com");
        request.setVersion("2017-05-25");
        request.setAction("SendSms");
        request.putQueryParameter("RegionId", "cn-hangzhou");
        request.putQueryParameter("PhoneNumbers", "*******************");
        request.putQueryParameter("SignName", "********");
        request.putQueryParameter("TemplateCode", "*****************");
        request.putQueryParameter("TemplateParam", "{\"code\":\"123456\"}");
        try {
            CommonResponse response = client.getCommonResponse(request);
            System.out.println(response.getData());
        } catch (ServerException e) {
            e.printStackTrace();
        } catch (ClientException e) {
            e.printStackTrace();
        }
    }
