ETKORP CouchDB渲染附件

如何解决ETKORP CouchDB渲染附件

我的附件记录在沙发上。

要恢复，我使用以下代码。

@RequestMapping(value = "/getDocument",method = RequestMethod.GET)
    public ResponseEntity<String> getDocument(@RequestParam(value = "document_id",defaultValue = "") String document_id,@RequestParam(value = "anexo_id",defaultValue = "") String attch_id) throws IOException {

        document_id = URL.decodeParam(document_id);
        attch_id = URL.decodeParam(attch_id);
        
        MyRepository repo;
        
        try {
            repo = new WebhookRepository(Webhook.class,this.service.getDb());
            AttachmentInputStream attachment = this.service.getAttachment(repo,document_id,attch_id);
            
            
             
            
            return ResponseEntity.ok().body(attachment.toString());
            
        } catch (dbaccessException e) {
            ResponseEntity.ok().body(e.toString());
            
        } catch (MalformedURLException e) {
            // Todo Auto-generated catch block
            e.printstacktrace();
        }
        return null;
        
        
    }

但是邮递员收到的答案是：org.ektorp.AttachmentInputStream@7a32fb41

我需要返回渲染的图像或附件中记录的base64字符串。

如何制作？
