How to pass params into Services that I get from the gsp and I have in my Controller in Grails -

i've got params user enter in g:textfield in controller when call method save(), , need use value in services. how can pass params have in controller services or possible pass data directly services gsp??

i'm trying pass params equal gsp-controller when i'm trying access params in services, error: no such property: params

gsp:

<g:textfield name="enteremail" required=""/> 

controller:

save(){     def entermail = params.enteremail    } 

services:

def sendyouremail(emailtemplate emailtemplateinstance){          ....                 def entermail = params.enteremail        log.info "sending email"     string source = 'myemail'     destination destination = new destination([entermail])     content subject = new content('test')     body body = new body().withhtml(new content(output.tostring()))     message message = new message(subject, body)     amazonwebservice.ses.sendemail(new sendemailrequest(source, destination, message))   } 

the params attribute using in controllers dynamic attribute grails added @ runtime. can't use service class.

it's bad idea params service, can using line:

org.springframework.web.context.request.requestcontextholder.currentrequestattributes().params 

a idea use command: plain groovy/java object parameters bound request, , send command service. doing that, remove dependency between service class (business layer) , params map (web layer): easier test , reusable other parts (you can create command whatever want).

command:

class mailcommand {     string enteremail } 

controller:

def mailservice def save(mailcommand mailcommand){     mailservice.sendyouremail(mailcommand, mailtemplate) } 

mailservice class:

def sendyouremail(mailcommand mailcommand, emailtemplate emailtemplateinstance){     def entermail = mailcommand.enteremail        ... }
