1.准备工作,需要购买短信以及新增短信模板

2.maven导入springboot sdk

    <!--阿里云短信-->
        <dependency>
            <groupId>com.aliyun</groupId>
            <artifactId>aliyun-java-sdk-core</artifactId>
            <version>4.0.3</version>
        </dependency>

3.java代码

    @GetMapping("/sentMsgCode")
    public RestResult sentMsgCode(@RequestParam(name = "phone") String phone) {
        String vailCode = "123456";
        JsonObject jsonObject = new JsonObject();
        jsonObject.addProperty("code",vailCode);
    //开通短信时的accessKeyId，secret
        DefaultProfile profile = DefaultProfile.getProfile("cn-hangzhou", "accessKeyId", "secret");
        IAcsClient client = new DefaultAcsClient(profile);
        CommonRequest request = new CommonRequest();
            request.setMethod(MethodType.POST);
            request.setDomain("dysmsapi.aliyuncs.com");
            request.setVersion("2017-05-25");
            request.setAction("SendSms");
            request.putQueryParameter("RegionId", "cn-hangzhou");
            request.putQueryParameter("PhoneNumbers", phone);
            request.putQueryParameter("SignName", "代码网");
        //这里填写审核通过后短信模板的code
            request.putQueryParameter("TemplateCode", "SMS_189033695");
            request.putQueryParameter("TemplateParam", jsonObject.toString());
        try {
            CommonResponse response = client.getCommonResponse(request);
        } catch (ServerException e) {
            e.printStackTrace();
        } catch (ClientException e) {
            e.printStackTrace();
        }
        return RestResult.success();
    }
