I am interested to know, is there is a manner to configure the logger os spring integration package in debug mode but without messages (quite large content).
My problem now resides more on understand my configuration than what i have done with the data.
Kind Regards.
See Wire-Tap pattern and Logging Channel Adapter.
The first one will let to to track a message journey through you flow and the second one will let you to configure whatever you want to log with its logExpression option.
See docs for more info:

Im using EmbeddedActiveMQBroker and wonder, how to create queue for Spring test?
Tried this, but failed :
getBrokerService().setDestinations(new ActiveMQQueue[] {new ActiveMQQueue("reply-queue")});
Queues and Topics are auto-created by default. Simply start the broker and client connections will create the destinations for you.
If you really must have the destination to exist before the client connection, you can use brokerService.getAdminView().addQueue(String queueName)

When i scan the Whatsapp code on my phone, the website switches IMMEDIATELY to the actual whatsapp page with the chats and all. I was wondering, how does the whole process look like? When i scan, my mobile probably recognized the code that's stored on the server and sends an Ajax request, but then how does the browser realize that the server received the request? is there some kind of "reverse Ajax" request from server to client? It happens so fast it's astonishing, and i really want to know what's up (heyoo sorry for the pun).
Thanks for responses in advance!
I did not check their code but it must be WebSockets.

I'm writing an web application where I'm using python-eve + mongodb for rest api and angular2 for front end.
Now I'm not sure how to manage user session in python-eve after authentication.
Do I need to write custom middle-ware like Django provide by default?
Any help would be appreciated.
Thanks,
Shashank
Well you are using a REST API and one of the core principles of REST is, precisely, the lack of state/session. Each request carries an authorisation token (or equivalent info depending on the type of authentication) since the server does not maintain state between sessions.
With this being said I know that people have been doing exactly what you are asking for, but really, I would not do that in a REST context.

Is it a good idea to use a message queue as websocket server in production (instead of Java EE #ServerEndpoint)?
It would establish a loose coupling towards the JS client and perhaps reduce the load from the application, but are there major disadvantages? Should one really expose a MQ over the web?
One can send messages to websocket clients from within a java web application without the help of a message queue. And this is a good enough solution as long as you do not need the additional features that message queues have to offer (QoS 1/2, Retained messages, Last Will and Testament, ... for some more benefits of using a mq see for example: http://www.hivemq.com/mqtt-over-websockets-with-hivemq/)

I would like to use "Spring Session" in my current project, but it seems that currently only Redis is a supported backend database. The official documentation is not talking about any other support yet.
Are there alternative implementations for other databases? For example, what about Memcached or Couchbase Support, which are fast Key-/Value Stores as well?
AFAIK only redis and hazelcast is supported but maybe you can find some 3rd party. Or you might want to implement it by yourself (and make it open source). It does not seems to be that complicated - see
https://github.com/spring-projects/spring-session/blob/1.0.1.RELEASE/samples/hazelcast/src/main/java/sample/Initializer.java
It looks like you just need to implement your SessionRepository and use proper HTTP filter.
