Spring Integration DefaultFtpSessionFactory timeout parameters details

Question

I am configuring a ftpClientFactory using org.springframework.integration.ftp.session.DefaultFtpSessionFactory.

I noticed it has 3 timeout related parameters. connectTimeout, defaultTimeout and dataTimeout.

I was reading the documentation but I could not find the exactly details about those properties. I am guessing that the dataTimeout is a timeout for sending the file. connectTimeout is for establishing a connection with the FTP server. And the defaultTimeout is for both???

I could not find a place to check if my understanding is correct. Does anyone knows where to find it or can anyone confirm it to me based on experience?

Answer 1

connectTimeout ends in timeout argument of Socket.connect of both control and data connection.

defaultTimeout ends in Socket.setSoTimeout of the control connection.

dataTimeout ends in Socket.setSoTimeout of the data connection.
