阿里云短信服务

1.需要到阿里云开通模板管理和签名管理，截图如下：

 

 

 

 2.导入maven依赖

<dependency>
   <groupId>com.alibaba</groupId>
   <artifactId>fastjson</artifactId>
</dependency>
<dependency>
   <groupId>com.aliyun</groupId>
   <artifactId>aliyun-java-sdk-core</artifactId>
</dependency>

3.application.properties

# 服务端口
server.port=8005
# 服务名
spring.application.name=service-msm

spring.redis.host=192.168.10.100
spring.redis.port=6379
spring.redis.database= 0
spring.redis.timeout=1800000

spring.redis.lettuce.pool.max-active=20
spring.redis.lettuce.pool.max-wait=-1
#最大阻塞等待时间(负数表示没限制)
spring.redis.lettuce.pool.max-idle=5
spring.redis.lettuce.pool.min-idle=0
#最小空闲

#返回json的全局时间格式
spring.jackson.date-format=yyyy-MM-dd HH:mm:ss
spring.jackson.time-zone=GMT+8

#mybatis日志
mybatis-plus.configuration.log-impl=org.apache.ibatis.logging.stdout.StdOutImpl

# nacos服务地址
spring.cloud.nacos.discovery.server-addr=127.0.0.1:8848

4.utils

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;
    }
}

5.启动类

@SpringBootApplication(exclude = DataSourceAutoConfiguration.class)
public class ServiceMsmApplication {

    public static void main(String[] args) {
        SpringApplication.run(ServiceMsmApplication.class, args);
    }

}

6.controller

@RestController
@RequestMapping("/edumsm/msm")
@CrossOrigin
public class MsmController {

    @Autowired
    private MsmService msmService;

    @Autowired
    private RedisTemplate<String,String> redisTemplate;

    //发送短信的方法
    @GetMapping("send/{phone}")
    public R sendMsm(@PathVariable String phone) {
        //1 从redis获取验证码，如果获取到直接返回
        String code = redisTemplate.opsForValue().get(phone);
        if(!StringUtils.isEmpty(code)) {
            return R.ok();
        }
        //2 如果redis获取 不到，进行阿里云发送
        //生成随机值，传递阿里云进行发送
        code = RandomUtil.getFourBitRandom();
        Map<String,Object> param = new HashMap<>();
        param.put("code",code);
        //调用service发送短信的方法
        boolean isSend = msmService.send(param,phone);
        if(isSend) {
            //发送成功，把发送成功验证码放到redis里面
            //设置有效时间
            redisTemplate.opsForValue().set(phone,code,5, TimeUnit.MINUTES);
            return R.ok();
        } else {
            return R.error().message("短信发送失败");
        }
    }
}

7.service

@Service
public class MsmServiceImpl implements MsmService {

    //发送短信的方法
    @Override
    public boolean send(Map<String, Object> param, String phone) {
        if(StringUtils.isEmpty(phone)) return false;

        DefaultProfile profile =
                DefaultProfile.getProfile("default", "LTAI4GDTqjJkxrB353q44ejE", "rdy8GeTHEYeKOGrY1EJ8pKGdQodMSv");
        IAcsClient client = new DefaultAcsClient(profile);

        //设置相关固定的参数
        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");

        //设置发送相关的参数
        request.putQueryParameter("PhoneNumbers",phone); //手机号
        request.putQueryParameter("SignName","天下技术教育管理网站"); //申请阿里云 签名名称
        request.putQueryParameter("TemplateCode","SMS_189617902"); //申请阿里云 模板code
        request.putQueryParameter("TemplateParam", JSONObject.toJSONString(param)); //验证码数据，转换json数据传递

        try {
            //最终发送
            CommonResponse response = client.getCommonResponse(request);
            boolean success = response.getHttpResponse().isSuccess();
            return success;
        }catch(Exception e) {
            e.printStackTrace();
            return false;
        }

    }
}
