grails async bootstrap

问题

Is it possible to use a service asynchronously in the grails bootstrap class? I am trying to do the following in grails-2.0.4 and the grails-executor-plugin, but only the first log message appears:

class BootStrap {

def myService

def init = { servletContext ->

    log.info("Bootstrapping")

    runAsync {
        log.info("Doing myService async ")
        myService.doSomething()
    }

}

There is no error message, just no output from the second log statement. Thanks a lot in advance!

Remove runAsync closure - it is not the right place for it. You can use closures like production and development here for different environments:

class BootStrap {

def myService

def init = { servletContext ->
    log.info("Bootstrapping")
    development {
        log.info("Doing myService async ")
        myService.doSomething()
    }
}

class MyService {
    def doSomething() {
        runAsync {
            // executed asynchronously
        }
    }
}
