如何在Spring Integration中使用通道但仅使用Java配置

Question

I have been reading the Spring Documentation and forums on Internet. I did something very similar to this: sftp with java config in spring

The point is I would like to use the channel to send a message, So I've created a method like this one

 private void MethodToSendMessageUsingSftp(MessageChannel channel, File file){ final Message<File> message = MessageBuilder.withPayload(file).build(); channel.send(message); } 

But I don't know how to get the channel in order to set it into the MethodToSendMessageUsingSftp method, and send the message.

By the way, I'm doing all these things just because I'm changing some stuff from xml to java config in my projects:

So, my old project looks like this:

<bean id="uploadToSftpTasklet" class="someClass" scope="step">
    <property name="sftpChannel" ref="sftpChannel"/>
</bean>

<int:channel id="sftpChannel"/>

<int-sftp:outbound-channel-adapter id="sftpOutboundAdapter"
                                   channel="sftpChannel"
                                   session-factory="sftpSessionFactory"
                                   remote-directory-expression="whatever"
                                   charset="UTF-8"
                                   auto-create-directory="true"
                                   use-temporary-file-name="false"
</int-sftp:outbound-channel-adapter>

If you see, in my uploadToSftpTasklet I'm referencing to the sftpChannel , and that is what I want to do using java config.

Let me guess: that method is a part of some service in your application, managed bean. So, you can just @Autowired that channel into this service and go with the logic.

Although, to be honest, your question isn't clear. Everything in Spring Integration is a bean and fully based on the Spring Framework. So, dependency injection rules and all the configuration tricks are applied here as well.
