Question

我还使用了自己的DefaultMailHeaderMapper实现，并设置了embedded-parts-as-bytes = true。

但是我有一个问题-我无法获得电子邮件附件。

我收到消息，但无法获取附件，因为从日志中可以看到，附件没有边界（例如，我将.gitignore文件附加到邮件中），因此MimeMessage解析器没有没有看到附件：

例如，下面我不使用headerMapper显示代码：

这是Spring Integration的错误，还是我必须添加一些配置？我使用的是Spring Integration 4.3.17，我也在5.0.5版本上尝试过。

Answer 1

有关更多信息，请参见JIRA：https://jira.spring.io/browse/INT-4299。

从版本5.2开始，我们引入了autoCloseFolder，您可以在MailReceiver到false上进行配置。这样一来，与禁用的headerMapper一起，您将在产生的消息MimeMessage中拥有完整的原始payload。因此，您可以根据需要解析下游的附件。

然后，如果需要，您需要从Folder关闭IntegrationMessageHeaderAccessor.CLOSEABLE_RESOURCE。

在Spring Integration中获取带有原始标题和附件的电子邮件
