Executing scripts in a grails Job - grails

Question

I am working on two parts of a program. One that creates small groovy scripts and another that executes them in a Job. Each script is used to convert information from a map to a Domain object. The job will then save the domain object for future use.
Here is a small example.
Domain
class Report {
Date date
Country country
}
Map
Map<String, String> map = new HashMap<String, String>();
map.put("date", "2015-04-21 11:31:11");
map.put("country", "United States");
Date Script
String script = "x.date = Date.parse('y-M-d h:m:s', y['date'])"
The script is currently executed using Eval.
Eval(report, map, script)
There are other more complicated scripts that need to look up information and make decisions based on values.
The date script works fine but when the country script executes I get an error.
Country Script
String script = "import app.Country\nx.country = Country.findByName(y['country'])"
Error
Script1.groovy: 1: unable to resolve class app.Country
It seems like the Country class is not getting loaded in the call to Eval. How can I do an import in Eval? Should I use Eval or GroovyShell?

Answer 1

You need to instantiate a GroovyShell passing as argument the grailsApplication class loader, see the example below:
Bootstrap.groovy
Map bindingValues = new HashMap()
bindingValues.sessionFactory = sessionFactory
bindingValues.propertyInstanceMap = propertyInstanceMap
bindingValues.dataSource = dataSource
bindingValues.ctx = grailsApplication.mainContext
GroovyShell gs = new GroovyShell(grailsApplication.classLoader, new Binding(bindingValues))
gs.evaluate new File("docs/CargaAvaliacoes.groovy")
CargaAvaliacoes.groovy
import avaliacao.Colaborador
import modelo.ModeloAvaliacao
import programa.Programa
def programa = Programa.get(1)
def modelo = ModeloAvaliacao.get(1)
def avaliadores = ["02270789332":"1020016","11388449681":"1010002","02231772331":"1010004","04247774332":"1020002"]
def avaliacaoService = ctx.getBean("avaliacaoService")
avaliadores.each {
def avaliador = Colaborador.findByCpf(it.key)
def avaliados = Colaborador.findAllBySetorAndCpfNotEqual(it.value,it.key)
avaliados.each {
avaliacaoService.cadastrar(programa, modelo, avaliador, it)
}
}
** You need to specify the grailsApplication.classLoader because this class loader is used to load the Grails domain classes.
