Pardon the lack of formatting, there was just too much information to learn plus watch live demos and type lists on an ipad. I will clean it up over the weekend. [cleaned up] Too much content is a good “problem” for a presentation to have.

libraries:

1. Spring Integration
2. Spring AMQP in release candidate mode.  Similar to Spring JMS but doesn’t hide it behind JMS. AMQP is an open wireless protocol.  Also use you set up a routing exchange and set up a routing key for clients to bind to.  For example news.star.us so can subscribe to different levels on broker. works with non Java clients

Events

• Has been in Spring since the very beginning
• interface ApplicationEventPublisherAware allows you to make a callback
• Interface ApplicationListener is called when event occurs, can use generics to say what type of events you care about
• Can do without forcing to extend spring interface as well

Messaging

• JmsTemplate – prefer CachingConnectionFactory to ensure sessions are reused
• Jms:listener-container defined in xml on a pojo
• Or use AmqpTemplate instead of JmsTemplate to use amqp, works the same as jmstemplate, for example you can call receive/send methods
• Amqp namespace released this week to support listeners
• Showed demo with rabbitmq including using web ui to see how many messages on queue
• RestTemplate for http messaging, can use HttpMessageConverters if need to be more specific

Mail

• SimpleMailMessage to create a message and inject MailSender to send it, good for simple messages, there is a mime one for more complex messsages
• Core Spring cannot receive e-mail. Spring Integration can

Polling

• Better to use events/messaging and only poll when you have to
• Lifecycle interface – start(), stop() and isRunning()
• SmartLifecycle does those three plus autostartup, phases and adds a callback on stop

Scheduling

• taskScheduler interface lets you schedule one time tasks, tasks at a fixed rate and tasks at a fixed delay
• Trigger interface lets you control the next execution time along with the Trigger Context that gives information about the last scheduled/actual time
• This means you don’t need quartz for simple operations
• The @Scheduled annotation lets you specify cron or fixed time/delay expressions instead of interfaces
• Can also create your own annotations to externalize the cron expression so using your custom annotation without duplicating the configuration of the cron expression

Pipes and filters

• Message can be any object as the payload with headers in a map, the message is immutable unless your payload itself is mutable
• MessageChannel can do point to point or publish subscribe, set channel, types in xml using  and can also set whether async
• A gateway can be one way or bidirectional
• Can use @publisher to put the result of a method or argument to go on a channel as a side effect of calling the method
• Filters return booleans
• Router directs to proper channel name
• Can route on payload type, header type etc
• Can split/aggregate channels
• Spring Integration 2.0 lets you use el to specify bindings, etc
• Can chain when don’t need explicit channel names
