Grails: Fetch domain object from service init method

I have created a service where in its init method it tries to load an object from the database, but this error is thrown:

Caused by IllegalStateException: Method on class [pruebainitservice.Conf] was used outside of a Grails application. If running in the context of a test using the mocking API or bootstrap Grails correctly.
->>   15 | init      in pruebainitservice.ConfService

|    615 | run       in java.util.concurrent.ThreadPoolExecutor$Worker
^    745 | run . . . in java.lang.Thread
| Error Forked Grails VM exited with error

I have created an example project, that basically does this; it just contains a domain class, a service, a controller with an action and its view. You can download from here https://github.com/okelet/grails-test-service-init.

Does anyone know why this happens?

Grails version: 2.3.8 Groovy Version: 2.1.8 JVM: 1.7.0_55 Vendor: Oracle Corporation OS: Linux

Regards and thanks in advance.

looks like @PostConstruct annotation is using it's own ClassLoader, hence the exception.

I'd use InitializingBean interface to do the init you need:

class SomeService implements InitializingBean {

  @Override
  void afterPropertiesSet() throws Exception {
    doStuffHere()
  }
}

UPDATE:

the only solution I could find was to call the init-method from BootStrap:

class SomeService {

  void init(){
    log.debug("Cargando configuración...")
    def confs = Conf.findAll()
     // the rest
  }
}

and 

class BootStrap {

  def confService

    def init = { servletContext ->
      confService.init()
    }
    def destroy = {
    }
}
