Spring Integration namespaces in resources.groovy

Spring Integration relies heavily on namespaces usage, so if you need to use it, this can be easily defined in Grails Spring DSL:

beans = {
  xmlns integration:"http://www.springframework.org/schema/integration"
  xmlns mail:"http://www.springframework.org/schema/integration/mail"
  xmlns jms:"http://www.springframework.org/schema/integration/jms"

}

After that you can define your channels like:

  integration.channel(id:'inboundEmailChannel')
