Grails: Fetch domain object from service init method - grails

Question

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

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.

Answer 1

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 = {
}
}
