Java 生成发送短信验证码（阿里云）

创建 RandomUtil 工具类

public class RandomUtil {
    
    

    private static final Random random = new Random();

    private static final DecimalFormat fourdf = new DecimalFormat("0000");

    private static final DecimalFormat sixdf = new DecimalFormat("000000");

    public static String getFourBitRandom() {
    
    
        return fourdf.format(random.nextInt(10000));
    }

    public static String getSixBitRandom() {
    
    
        return sixdf.format(random.nextInt(1000000));
    }

    /**
     * 给定数组，抽取n个数据
     * @param list
     * @param n
     * @return
     */
    public static ArrayList getRandom(List list, int n) {
    
    

        Random random = new Random();

        HashMap<Object, Object> hashMap = new HashMap<Object, Object>();

		// 生成随机数字并存入HashMap
        for (int i = 0; i < list.size(); i++) {
    
    

            int number = random.nextInt(100) + 1;

            hashMap.put(number, i);
        }

		// 从HashMap导入数组
        Object[] robjs = hashMap.values().toArray();

        ArrayList r = new ArrayList();

		// 遍历数组并打印数据
        for (int i = 0; i < n; i++) {
    
    
            r.add(list.get((int) robjs[i]));
            System.out.print(list.get((int) robjs[i]) + "\t");
        }
        System.out.print("\n");
        return r;
    }
}

创建 ConstantPropertiesUtils工具类

@Component
public class ConstantPropertiesUtils implements InitializingBean {
    
    

    @Value("${aliyun.sms.regionId}")
    private String regionId;

    @Value("${aliyun.sms.accessKeyId}")
    private String accessKeyId;

    @Value("${aliyun.sms.secret}")
    private String secret;

    public static String REGION_Id;
    public static String ACCESS_KEY_ID;
    public static String SECRECT;

    @Override
    public void afterPropertiesSet() throws Exception {
    
    
        REGION_Id=regionId;
        ACCESS_KEY_ID=accessKeyId;
        SECRECT=secret;
    }
}

使用

@Service
public class MsmServiceImpl implements MsmService {
    
    
    @Override
    public boolean send(String phone, String code) {
    
    
        //判断手机号是否为空
        if(StringUtils.isEmpty(phone)) {
    
    
            return false;
        }
        //整合阿里云短信服务
        //设置相关参数
        DefaultProfile profile = DefaultProfile.
                getProfile(ConstantPropertiesUtils.REGION_Id,
                        ConstantPropertiesUtils.ACCESS_KEY_ID,
                        ConstantPropertiesUtils.SECRECT);
        IAcsClient client = new DefaultAcsClient(profile);
        CommonRequest request = new CommonRequest();
        //request.setProtocol(ProtocolType.HTTPS);
        request.setMethod(MethodType.POST);
        request.setDomain("dysmsapi.aliyuncs.com");
        request.setVersion("2017-05-25");
        request.setAction("SendSms");

        //手机号
        request.putQueryParameter("PhoneNumbers", phone);
        //签名名称
        request.putQueryParameter("SignName", "阿里云手机短信验证");
        //模板code，阿里云短信服务（模板code）
        request.putQueryParameter("TemplateCode", "SMS_180051135");
        //验证码  使用json格式   {"code":"123456"}
        Map<String,Object> param = new HashMap();
        param.put("code",code);
        request.putQueryParameter("TemplateParam", JSONObject.toJSONString(param));

        //调用方法进行短信发送
        try {
    
    
            CommonResponse response = client.getCommonResponse(request);
            System.out.println(response.getData());
            return response.getHttpResponse().isSuccess();
        } catch (ServerException e) {
    
    
            e.printStackTrace();
        } catch (ClientException e) {
    
    
            e.printStackTrace();
        }
        return false;
    }
}
