使用 Amazon SES 时出现“java.lang.ClassNotFoundException: io.awspring.cloud.jdbc.config.annotation.AmazonRdsInstanceConfiguration”

Question

我正在尝试让我的 spring 应用程序与 Amazon SES 一起运行，但在构建过程中不断出现异常，说“java.lang.ClassNotFoundException：io.awspring.cloud.jdbc.config.annotation.AmazonRdsInstanceConfiguration”我正在关注一个例子在线 https://stackabuse.com/guide-to-simple-email-service-aws-ses-with-spring-boot-and-spring-cloud/

这是我的配置文件

import com.amazonaws.auth.AWSStaticCredentialsProvider;
import com.amazonaws.auth.BasicAWSCredentials;
import com.amazonaws.services.simpleemail.AmazonSimpleEmailService;
import com.amazonaws.services.simpleemail.AmazonSimpleEmailServiceClientBuilder;
import io.awspring.cloud.ses.SimpleEmailServiceMailSender;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.mail.MailSender;

@Configuration
public class AmazonSESConfig {

    @Value("${amazon.aws.accessKey}")
    private String accessKey;
    @Value("${amazon.aws.secretKey}")
    private String secretKey;

    @Value("${amazon.aws.region}")
    private String region;

    @Bean
    public AmazonSimpleEmailService amazonSimpleEmailService() {
        BasicAWSCredentials credentials = new BasicAWSCredentials(accessKey, secretKey);
        return AmazonSimpleEmailServiceClientBuilder
                .standard()
                .withCredentials(new AWSStaticCredentialsProvider(credentials))
                .withRegion(region)
                .build();

    }

    @Bean
    public MailSender mailSender(AmazonSimpleEmailService amazonSimpleEmailService) {
        return new SimpleEmailServiceMailSender(amazonSimpleEmailService);
    }
}

这是我的属性文件

amazon.aws.accessKey=ACCESS_KEY
amazon.aws.secretKey=SECRET_KEY
amazon.aws.region=ca-central-1

这是我的服务档案

@Service
public class CorrespondenceService {

    @Autowired
    private MailSender mailSender;

    public void sendMail(){
    
        SimpleMailMessage simpleMailMessage = new SimpleMailMessage();
        simpleMailMessage.setFrom("[email protected]");
        simpleMailMessage.setTo("[email protected]");
        simpleMailMessage.setSubject("Test");
        simpleMailMessage.setText("This email is a test");

        mailSender.send(simpleMailMessage);


    }

}

最后是来自控制台的错误。
