springboot定时发送短信代码

这里提供一个简单的示例代码，使用Spring Boot的定时任务功能和阿里云短信服务SDK实现定时发送短信：

1. 添加阿里云短信服务SDK依赖

<dependency>
    <groupId>com.aliyun</groupId>
    <artifactId>aliyun-java-sdk-core</artifactId>
    <version>4.5.5</version>
</dependency>
<dependency>
    <groupId>com.aliyun</groupId>
    <artifactId>aliyun-java-sdk-dysmsapi</artifactId>
    <version>1.0.0</version>
</dependency>

2. 在application.yml中添加阿里云短信服务配置

aliyun:
  sms:
    accessKeyId: <your_access_key_id>
    accessKeySecret: <your_access_key_secret>
    signName: <your_sms_sign_name>
    templateCode: <your_sms_template_code>

3. 编写定时任务类

import com.aliyuncs.DefaultAcsClient;
import com.aliyuncs.exceptions.ClientException;
import com.aliyuncs.profile.DefaultProfile;
import com.aliyuncs.profile.IClientProfile;
import com.aliyuncs.sms.model.v20170525.SendSmsRequest;
import com.aliyuncs.sms.model.v20170525.SendSmsResponse;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;

@Component
public class SmsTask {

    @Autowired
    private SmsService smsService;

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

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

    @Scheduled(cron = "0 0 8 * * ?") // 每天早上8点执行
    public void sendSms() {
        String phoneNumbers = "<your_phone_number>";
        String templateParam = "{\"code\":\"123456\"}"; // 短信模板参数，这里假设模板中只有一个占位符code
        try {
            SendSmsResponse response = smsService.sendSms(phoneNumbers, templateCode, templateParam, signName);
            if ("OK".equals(response.getCode())) {
                System.out.println("短信发送成功！");
            } else {
                System.out.println("短信发送失败：" + response.getMessage());
            }
        } catch (ClientException e) {
            e.printStackTrace();
        }
    }
}

4. 编写短信服务类

import com.aliyuncs.DefaultAcsClient;
import com.aliyuncs.exceptions.ClientException;
import com.aliyuncs.http.MethodType;
import com.aliyuncs.profile.DefaultProfile;
import com.aliyuncs.profile.IClientProfile;
import com.aliyuncs.sms.model.v20170525.SendSmsRequest;
import com.aliyuncs.sms.model.v20170525.SendSmsResponse;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

@Service
public class SmsService {

    @Autowired
    private AliyunSmsProperties aliyunSmsProperties;

    public SendSmsResponse sendSms(String phoneNumbers, String templateCode, String templateParam, String signName) throws ClientException {
        IClientProfile profile = DefaultProfile.getProfile("cn-hangzhou", aliyunSmsProperties.getAccessKeyId(), aliyunSmsProperties.getAccessKeySecret());
        DefaultAcsClient client = new DefaultAcsClient(profile);

        SendSmsRequest request = new SendSmsRequest();
        request.setMethod(MethodType.POST);
        request.setPhoneNumbers(phoneNumbers);
        request.setSignName(signName);
        request.setTemplateCode(templateCode);
        request.setTemplateParam(templateParam);

        return client.getAcsResponse(request);
    }
}

注意事项：

- 需要替换代码中的阿里云短信服务配置和手机号码
- 短信模板中的占位符和templateParam参数需要根据实际情况进行修改
- 在使用定时任务时需要开启@EnableScheduling注解
