Java DSL: Lambdas for Namespace Factories #117

Closed artembilan closed 10 years ago

artembilan commented 10 years ago

Add Function and Consumer copies from Java 8
Rework some functional interfaces to Function or Consumer
Introduce Channels, MessageHandlers, MessageProducers, MessageSources, MessagingGateways
some convenient wrappers for Namespace Factories to be used from Lambdas
Add Lambda-methods for those new wrappers
Provide some refactoring
Upgrade to Boot 1.1.7

@garyrussell , review is welcome. But if you just say "OK", I'll merge it as is and go ahead with FunctionExpression and SubFlow. Thanks in advance.

Otherwise LGTM; however, I wonder how practical the DSL will be with Java 7 and below so perhaps Java 8 should be the minimum?

so perhaps Java 8 should be the minimum?

From one side there are enough request for DSL samples in Java 7 style. From other side there is an idea to have XD modules (tamplates) based on this DSL. And one more argument is Reactor, which is more Java 8, but still support Java 6. At least 1.1.x. Reactor 2.0 is Java 7 minimal. XD should pay attention to that if we are going to upgrade to Reactor 2.0.

Pushed.

Now all methods in the IntegrationFlows are .from(). Note: IntegrationFlowDefinition now has additional methods - .handleWithAdapter() to rely on the Adapters Lambda.
