customized tcp-connection-factory

[olegtikhonov]

Hello,
I'm curious if is it possible to customize a tcp connection factory.
Say, I would like to extend

TcpNetServerConnectionFactory

. How can I do that? I mean by configuration file.

For example,

    <int-ip:tcp-connection-factory id="testServer"
                                   type="server"
                                   port="10011"
                                   task-executor="exec" single-use="true"
                                   interceptor-factory-chain=""
            />

Here is not a mention about type of connection factory. What should I do to nail a problem?

Thanks in advance,
Oleg

Hi!

Here is not a mention about type of connection factory

What do you mean? To tell to <int-ip:tcp-connection-factory> tag to use your TcpNetServerConnectionFactory subclass?
What is a problem to configure it as regular bean:

<bean id="serverConnectionFactory" class="com.my.proj.tcp.MyTcpNetServerConnectionFactory"
         c:port="10011" p:singleUse="true" />

Any Spring custom tags provide in the end some specific beans of some built-in types. And in many cases they provide not only one bean... That's why similar tags don't allow to customize a general contract between tag and provided beans. But you always can configure them all as <bean ...> and you may end up with the same behaviour. E.g. configure Spring Security with regular beans very difficult.
So be carefull to provide some customization of existing stategies.

From other side: is there really a reason to extend TcpNetServerConnectionFactory ?

Take care,
Artem

Thanks Artem!

To be honest, I'm not sure if I have to extend it.
I would like to get notifications about: socket opened/closed, listening on port #... . In addition to be able to disconnect & reconnect by specific criteria. May be there are other ways to do so.

KR,
Oleg

socket opened/closed, listening on port

Yes it is here now: http://static.springsource.org/sprin...3.0-tcp-events
And this upcoming Pull Request: https://github.com/SpringSource/spri...2/files#diff-8

There is no so much changes in the 3.0 yet, so, you won't have a lot problem to upgrade your application to Spring Integration 3.0.M1
