调用阿里云短信接口，实现验证码功能

@Component
@Data
public class MessgeUtils {

public static ExpiringMap map = null;

//产品名称:云通信短信API产品,开发者无需替换

public static SendSmsResponse sendSms(String phone , String code, String TemplateCode)  {
    //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

    if(null != sendSmsResponse && sendSmsResponse.getCode().equals("OK")){
        log.info(">>>验证码发送成功+" + code);
        //发送成功，把验证码与手机号绑定，用于验证
        map.put(phone,code,120000, TimeUnit.MILLISECONDS);
    }
    return sendSmsResponse;
}

public MessgeUtils(){
    map = ExpiringMap.builder().variableExpiration().expirationPolicy(ExpirationPolicy.CREATED).build();
}


/**

 * @return

    log.info(">>>发送验证码" + content);
    map.put(mobile,content,60000, TimeUnit.MILLISECONDS);
    return content;
}

}
