springboot调用阿里云发送国际短信代码实现

首先，你需要在阿里云短信控制台中创建签名和模板，并获取到 AccessKeyId 和 AccessKeySecret。

接下来，在Spring Boot项目中添加阿里云 Java SDK的依赖：

<dependency>
    <groupId>com.aliyun</groupId>
    <artifactId>aliyun-java-sdk-core</artifactId>
    <version>4.5.3</version>
</dependency>
<dependency>
    <groupId>com.aliyun</groupId>
    <artifactId>aliyun-java-sdk-dysmsapi</artifactId>
    <version>1.0.0</version>
</dependency>

然后，在项目的 application.properties 文件中添加阿里云短信服务的相关配置：

aliyun.sms.accessKeyId=yourAccessKeyId
aliyun.sms.accessKeySecret=yourAccessKeySecret
aliyun.sms.signName=yourSignName
aliyun.sms.templateCode=yourTemplateCode

在代码中，你可以使用以下示例代码发送国际短信：

import com.aliyuncs.DefaultAcsClient;
import com.aliyuncs.IAcsClient;
import com.aliyuncs.exceptions.ClientException;
import com.aliyuncs.exceptions.ServerException;
import com.aliyuncs.profile.DefaultProfile;
import com.aliyuncs.profile.IClientProfile;
import com.aliyuncs.sms.model.v20170628.SendSmsRequest;
import com.aliyuncs.sms.model.v20170628.SendSmsResponse;

import java.util.Arrays;

public class SmsUtil {

    private String accessKeyId;
    private String accessKeySecret;
    private String signName;
    private String templateCode;

    public SmsUtil(String accessKeyId, String accessKeySecret, String signName, String templateCode) {
        this.accessKeyId = accessKeyId;
        this.accessKeySecret = accessKeySecret;
        this.signName = signName;
        this.templateCode = templateCode;
    }

    public boolean sendSms(String phoneNumber, String message) {
        IClientProfile profile = DefaultProfile.getProfile("default", accessKeyId, accessKeySecret);
        DefaultProfile.addEndpoint("default", "default", "Dysmsapi", "dysmsapi.aliyuncs.com");
        IAcsClient client = new DefaultAcsClient(profile);
        SendSmsRequest request = new SendSmsRequest();
        request.setPhoneNumbers(phoneNumber);
        request.setSignName(signName);
        request.setTemplateCode(templateCode);
        request.setTemplateParam("{\"code\":\"" + message + "\"}");
        try {
            SendSmsResponse response = client.getAcsResponse(request);
            if (response.getCode() != null && response.getCode().equals("OK")) {
                return true;
            }
        } catch (ServerException e) {
            e.printStackTrace();
        } catch (ClientException e) {
            e.printStackTrace();
        }
        return false;
    }

    public static void main(String[] args) {
        // 使用示例
        SmsUtil smsUtil = new SmsUtil(
                "yourAccessKeyId",
                "yourAccessKeySecret",
                "yourSignName",
                "yourTemplateCode"
        );
        boolean result = smsUtil.sendSms("+86xxxxxxxxxxx", "yourMessage");
        System.out.println(result);
    }
}

其中，phoneNumber 是接收短信的手机号码，message 是短信内容，可以根据模板中定义的变量替换。调用 sendSms 方法即可发送短信。
