What is the difference between Inbound Channel Adaptor and Outbound Channel Adaptor in Spring Integration FTP. Which one I should I use and when?
I read from documentation that outbound can send any type of file(like byte[], String, java.io.File) but Inbound is restricted for File type only. Is that only difference or anything else?
回答1:
I suggest you to read a theory first of all.
Any Inbound adapter is intended to get data from external system. Outbound - to put data. E.g. simple case: JDBC Inbound performs a SELECT from DB, Outbound - INSERT.
In case of FTP: the first one to read files from FTP, the last - to write them.
