使用阿里云短信发送验证码

1，目录结构

2，相关依赖

  <!-- https://mvnrepository.com/artifact/com.alibaba/fastjson -->
        
            com.alibaba
            fastjson
            1.2.72
        
        
        
            com.aliyun
            aliyun-java-sdk-core
            4.5.2
        

3，配置类

定义了连接阿里云的key秘钥等信息

@Component
@PropertySource({"classpath:oss.properties"})
public class OSSConfig implements InitializingBean {
    // Endpoint以青岛为例，其它Region请按实际情况填写。
    @Value("${endpoint}")
    private String endpoint;
    @Value("${accessKeyId}")
    private String accessKeyId;
    @Value("${accessKeySecret}")
    private String accessKeySecret;

    public static String ENDPOINT;
    public static String ACCESSKEYID;
    public static String ACCESSKEYSECRET;
    @Override
    public void afterPropertiesSet() throws Exception {
        ENDPOINT=endpoint;
        ACCESSKEYID=accessKeyId;
        ACCESSKEYSECRET=accessKeySecret;
    }
}

4，controller

发送成功后将验证码存在了redis缓存中，设置过期时间，每次发送前先读取，如果不存在就发送，存在就直接返回

@Controller
@CrossOrigin
@RequestMapping("/msm")
public class MsmController {
    @Autowired
    private MsmService msmService;
    @Autowired
    private RedisTemplate<String,String> redisTemplate;

    @GetMapping("/send/{phone}")
    @ResponseBody
    public String sendMsm(@PathVariable("phone") String phone){
        //1，从redis中查询验证码
        String code = redisTemplate.opsForValue().get(phone);
        if (!StringUtils.isEmpty(code)){
            return "已发送";
        }
        //2，没有就生成
        code = RandomUtil.getFourBitRandom();
        Map<String,Object> map = new HashMap<>();
        map.put("code",code);
        Boolean success = msmService.sendMsm(map,phone);
        if (success){
            redisTemplate.opsForValue().set(phone,code,5, TimeUnit.MINUTES);
            return "成功";
        }
        return "失败";
    }
}

5，service发送短信

@Service
public class MsmServiceImpl implements MsmService {

    //发送短信
    @Override
    public Boolean sendMsm(Map<String, Object> map, String phone) {
        if (StringUtils.isEmpty(phone)){
            return false;
        }
        DefaultProfile profile = DefaultProfile.getProfile("default",OSSConfig.ACCESSKEYID,OSSConfig.ACCESSKEYSECRET);
        IAcsClient client = new DefaultAcsClient(profile);

        //设置参数（固定）
        CommonRequest request = new CommonRequest();
        request.setSysMethod(MethodType.POST);
        request.setSysDomain("dysmsapi.aliyuncs.com");
        request.setSysVersion("2017-05-25");
        request.setSysAction("SendSms");

        //设置发送参数
        request.putQueryParameter("PhoneNumbers",phone);
        request.putQueryParameter("SignName","纵横江湖");   //阿里云申请的签名
        request.putQueryParameter("TemplateCode","SMS_195190***");//申请的模板的code
        request.putQueryParameter("TemplateParam", JSONObject.toJSONString(map));

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

        return false;
    }
}
