您好！关于您的问题，我可以为您提供如下回答：
要通过邮箱发送
Java OSS 存储的图片，您可以先将图片从
OSS 中下载到本地，然后再将图片作为附件添加到您的邮件中发送。以下是示例代码：
```
java
import
java.io.File;
import
java.util.Properties;
import
javax.activation.DataHandler;
import
javax.activation.FileDataSource;
import
javax.mail.Message;
import
javax.mail.Session;
import
javax.mail.Transport;
import
javax.mail.internet.AddressException;
import
javax.mail.internet.InternetAddress;
import
javax.mail.internet.MimeMessage;
import
javax.mail.internet.MimeMultipart;
import
javax.mail.internet.MimeBodyPart;
import
javax.mail.internet.MimeUtility;
import com.aliyun.
oss.
OSS;
import com.aliyun.
oss.
OSSClientBuilder;
import com.aliyun.
oss.model.
OSSObject;
public class SendMailWithImage {
public static void main(String[] args) throws Exception {
// 配置
OSS信息
String endpoint = "<yourEndpoint>";
String accessKeyId = "<yourAccessKeyId>";
String accessKeySecret = "<yourAccessKeySecret>";
String bucketName = "<yourBucketName>";
String objectKey = "<yourObjectKey>";
String
ossFileName = "<your
OSSFileName>";
// 下载
OSS中的图片到本地
OSS ossClient = new
OSSClientBuilder().build(endpoint, accessKeyId, accessKeySecret);
OSSObject
ossObject =
ossClient.getObject(bucketName, objectKey);
ossClient.getObject(new GetObjectRequest(bucketName, objectKey), new File(
ossFileName));
ossClient.shutdown();
// 发送邮件
Properties props = new Properties();
props.put("mail.smtp.auth", "true");
props.put("mail.transport.protocol", "smtp");
props.put("mail.smtp.host", "<yourSmtpServer>");
Session session = Session.getInstance(props);
Message message = new MimeMessage(session);
message.setFrom(new InternetAddress("<yourEmail>"));
message.setRecipient(Message.RecipientType.TO, new InternetAddress("<recipientEmail>"));
message.setSubject("图片邮件");
message.setText("这是一封带有图片的邮件。");
MimeMultipart multipart = new MimeMultipart("related");
MimeBodyPart imagePart = new MimeBodyPart();
FileDataSource fds = new FileDataSource(
ossFileName);
imagePart.setDataHandler(new DataHandler(fds));
imagePart.setContentID("myImage");
imagePart.setFileName(MimeUtility.encodeText(fds.getName()));
multipart.addBodyPart(imagePart);
MimeBodyPart contentPart = new MimeBodyPart();
contentPart.setContent("<html><body><h1>这是一封带有图片的邮件。</h1><img src=\"cid:myImage\"></body></html>", "text/html;charset=utf-8");
multipart.addBodyPart(contentPart);
message.setContent(multipart);
Transport transport = session.getTransport();
transport.connect("<yourEmail>", "<yourPassword>");
transport.sendMessage(message, message.getAllRecipients());
transport.close();
System.out.println("邮件发送成功！");
}
}
```
需要注意的是，以上代码并未完整展示如何配置邮件发送方信息和接收方信息，以及如何配置
OSS的信息。您需要根据实际情况进行相应的修改。另外，您需要将以上代码中的 `"<yourEndpoint>"`、`"<yourAccessKeyId>"`、`"<yourAccessKeySecret>"`、`"<yourBucketName>"`、`"<yourObjectKey>"` 和 `"<your
OSSFileName>"` 替换为您实际使用的
OSS信息。
希望这个回答能够帮助到您，如果您还有其他问题，欢迎随时提问！
