我有一个文档服务器应用程序。对于从ftp文件夹中拾取并放入本地目录的文件，可以使用单独的流。第二个流程用于拾取文件并将其放入FTP位置。我为自己和自定义模式匹配器添加了一个AcceptOnceFileListFilter，在两种情况下都是相同的（某些东西）。本地目录以及ftp文件夹与此不同。
我需要在拾取后让源文件存在，因此我删除了deletesourcefiles属性。
有了这个，我面临着重复进入过滤器并进行处理的文件问题。如何使用AcceptOnceFileListFilter实现这一点？我无论如何都需要避免重复处理相同的文件。
这是我的整个配置。

编辑：
将配置从固定速率更改为固定延迟。我不记得为什么我上个月把它改成了固定费率！无论如何，到目前为止解决了大文件问题。但是，acceptoncefilter仍然没有完成它的工作。文件入站适配器拾取后，不会从本地目录中删除该文件。
还有另一个问题。有两个ftp通道具有不同的远程文件夹和不同的本地文件夹。我希望每个人都是单向的。意味着一个人应该从远程目录中获取文件并将其放在本地文件中，另一个应该反之亦然。由于上述问题，文件仍然在本地目录中，并被其他流程接收并放回远程目录！也不能使其中一个dir无效。请指导我，因为必须不删除远程目录上的文件。
