二、编写java工具类

package com.walkby.utils;

import com.aliyuncs.DefaultAcsClient;
import com.aliyuncs.IAcsClient;
import com.aliyuncs.dysmsapi.model.v20170525.SendSmsRequest;
import com.aliyuncs.dysmsapi.model.v20170525.SendSmsResponse;
import com.aliyuncs.exceptions.ClientException;
import com.aliyuncs.http.MethodType;
import com.aliyuncs.profile.DefaultProfile;
import com.aliyuncs.profile.IClientProfile;
import com.walkby.config.SMSConfig;
import lombok.extern.slf4j.Slf4j;
import org.springframework.stereotype.Component;

/**
 * @author 
 * 发送短信工具类
 */
@Component
@Slf4j
public class SendSms {

    //产品名称:云通信短信API产品,开发者无需替换
    static final String product = "Dysmsapi";
    //产品域名,开发者无需替换
    static final String domain = "dysmsapi.aliyuncs.com";

    /**
     * 短信验证
     * @param phone 手机号
     * @param code 验证码
     * @param templateCode 短信模版
     * @return
     * @throws ClientException
     */
    public static SendSmsResponse sendSms(String phone, String code,String templateCode) throws ClientException {
        //可自助调整超时时间
        System.setProperty("sun.net.client.defaultConnectTimeout", "10000");
        System.setProperty("sun.net.client.defaultReadTimeout", "10000");
        //初始化acsClient,暂不支持region化
        IClientProfile profile = DefaultProfile.getProfile("cn-hangzhou",
                SMSConfig.KEY_ID,SMSConfig.KEY);
        DefaultProfile.addEndpoint("cn-hangzhou", "cn-hangzhou", product, domain);
        IAcsClient acsClient = new DefaultAcsClient(profile);
        //组装请求对象-具体描述见控制台-文档部分内容
        SendSmsRequest request = new SendSmsRequest();
        request.setMethod(MethodType.POST);
        request.setPhoneNumbers(phone);
        request.setSignName(SMSConfig.SIGN_NAME);
        request.setTemplateCode(templateCode);
        request.setTemplateParam("{\"code\":\"" + code + "\"}");
        //选填-上行短信扩展码(无特殊需求用户请忽略此字段)
        //request.setSmsUpExtendCode("90997");
        //hint 此处可能会抛出异常，注意catch
        SendSmsResponse sendSmsResponse = acsClient.getAcsResponse(request);
//
        log.info("发送短信状态：{}", sendSmsResponse.getCode());
        log.info("发送短信消息：{}", sendSmsResponse.getMessage());
        return sendSmsResponse;
    }
}
