and on model

class authuser {      transient springsecurityservice      string username     string password     string email     boolean enabled = true     boolean accountexpired     boolean accountlocked     boolean passwordexpired      static transients = ['springsecurityservice']      static hasmany = [madebillings:billing, goodsbillings:goodsbill, approvedrequest:tenantrequest, journals:journal]      static constraints = {         username blank: false, unique: true         password blank: false         email blank: false, unique: true, email: true     }      static mapping = {         password column: '`password`'         tableperhierarchy false     }      set<authrole> getauthorities() {         authuserauthrole.findallbyauthuser(this).collect { it.authrole }     }      def beforeinsert() {         encodepassword()     }      def beforeupdate() {         if (isdirty('password')) {             encodepassword()         }     }      protected void encodepassword() {         password = springsecurityservice?.passwordencoder ? springsecurityservice.encodepassword(password) : password     }      string tostring() {         username     } } 

i try use http://localhost:8080/myapp/authuser/list?format=csv&extension=csv

i have found solution documentation on official plugin page

def list = {     if(!params.max) params.max = 10      if(params?.exportformat && params.exportformat != "html"){ //must change exportformat cause format reserved default grails format         response.contenttype = grailsapplication.config.grails.mime.types[params.exportformat]         response.setheader("content-disposition", "attachment; filename=authuser.${params.extension}")          exportservice.export(params.exportformat, response.outputstream,authuser.list(params), [:], [:])     }      //   [ authuserinstancelist: authuser.list( params ) ] have comment or give else clause since  response called before } 

you use grails export plugin export data excel, csv, pdf, etc. it's easy configure , use.
