FTP Session Factory
Spring Integration provides factories you can use to create FTP (or FTPS) sessions.
Default Factories
Starting with version 3.0, sessions are no longer cached by default. See FTP Session Caching. |
Before configuring FTP adapters, you must configure an FTP session factory.
You can configure the FTP Session Factory with a regular bean definition where the implementation class is o.s.i.ftp.session.DefaultFtpSessionFactory
.
The following example shows a basic configuration:
<bean id="ftpClientFactory"
class="org.springframework.integration.ftp.session.DefaultFtpSessionFactory">
<property name="host" value="localhost"/>
<property name="port" value="22"/>
<property name="username" value="kermit"/>
<property name="password" value="frog"/>
<property name="clientMode" value="0"/>
<property name="fileType" value="2"/>
<property name="bufferSize" value="100000"/>
</bean>
For FTPS connections, you can use o.s.i.ftp.session.DefaultFtpsSessionFactory
instead.
The following example shows a complete configuration:
<bean id="ftpClientFactory"
class="org.springframework.integration.ftp.session.DefaultFtpsSessionFactory">
<property name="host" value="localhost"/>
<property name="port" value="22"/>
<property name="username" value="oleg"/>
<property name="password" value="password"/>
<property name="clientMode" value="1"/>
<property name="fileType" value="2"/>
<property name="useClientMode" value="true"/>
<property name="cipherSuites" value="a,b.c"/>
<property name="keyManager" ref="keyManager"/>
<property name="protocol" value="SSL"/>
<property name="trustManager" ref="trustManager"/>
<property name="prot" value="P"/>
<property name="needClientAuth" value="true"/>
<property name="authValue" value="oleg"/>
<property name="sessionCreation" value="true"/>
<property name="protocols" value="SSL, TLS"/>
<property name="implicit" value="true"/>
</bean>
If you experience connectivity problems and would like to trace session creation as well as see which sessions are polled, you can enable session tracing by setting the logger to the TRACE level (for example, log4j.category.org.springframework.integration.file=TRACE ).

Now you need only inject these session factories into your adapters. The protocol (FTP or FTPS) that an adapter uses depends on the type of session factory that has been injected into the adapter.
A more practical way to provide values for FTP or FTPS session factories is to use Spring’s property placeholder support (See docs.spring.io/spring/docs/current/spring-framework-reference/core.html#beans-factory-placeholderconfigurer). |
