自定义附件存储 ​

模块将附件存储抽象出来, 与持久化逻辑进行拆分

默认实现了本地文件存储和Minio对象存储, 如果您需要进行存储方式自定义, 可通过实现AttachmentStorage接口实现:

java
@Component
public class MyAttachmentStorage implements AttachmentStorage {
  @Override
  public Attachment upload(MultipartFile multipartFile) throws Exception {
    // 上传逻辑...
  }
    
  @Override
  public void download(Attachment attachment, HttpServletResponse response) throws Exception {
    // 下载逻辑...
  }
    
  @Override
  public void remove(Attachment attachment) throws Exception {
    // 删除逻辑...
  }
}
@Component
public class MyAttachmentStorage implements AttachmentStorage {
  @Override
  public Attachment upload(MultipartFile multipartFile) throws Exception {
    // 上传逻辑...
  }
    
  @Override
  public void download(Attachment attachment, HttpServletResponse response) throws Exception {
    // 下载逻辑...
  }
    
  @Override
  public void remove(Attachment attachment) throws Exception {
    // 删除逻辑...
  }
}
