FTP/FTPS Adapters

Spring Integration provides support for file transfer operations with FTP and FTPS.

The File Transfer Protocol (FTP) is a simple network protocol that lets you transfer files between two computers on the Internet. FTPS stands for “FTP over SSL”.

You need to include this dependency into your project:

Maven
Gradle

<dependency>
    <groupId>org.springframework.integration</groupId>
    <artifactId>spring-integration-ftp</artifactId>
    <version>6.2.4</version>
</dependency>

compile "org.springframework.integration:spring-integration-ftp:6.2.4"

There are two actors when it comes to FTP communication: client and server. To transfer files with FTP or FTPS, you use a client that initiates a connection to a remote computer that is running an FTP server. After the connection is established, the client can choose to send or receive copies of files.

Spring Integration supports sending and receiving files over FTP or FTPS by providing three client-side endpoints: inbound channel adapter, outbound channel adapter, and outbound gateway. It also provides convenient namespace-based configuration options for defining these client components.

To use the FTP namespace, add the following to the header of your XML file:

xmlns:int-ftp="http://www.springframework.org/schema/integration/ftp"
xsi:schemaLocation="http://www.springframework.org/schema/integration/ftp
    https://www.springframework.org/schema/integration/ftp/spring-integration-ftp.xsd"
