Как передать список Джаспера в Граалей с помощью JasperService

Question

Вот мой класс домена

class User { 
    String admin 
    String name 
    String phoneNumber 
    String email 
    String questionSet 
} 

Вот мой view.gsp Джаспера сообщить

<g:jasperReport controller="profile" action="jasperdata" format="PDF" 
</g:jasperReport> 

А вот мой контроллер

def jasperService 
def jasperdata(){ 
    List listDetails = [] 
    Map mapDetails =[:] 
    Map result = [:] 
    def number=User.executeQuery('select phoneNumber from User') 
    mapDetails.put('phnno', number) 
    listDetails.add(mapDetails) 
    println listDetails 
    result.data = [] 
    result.data << [phnno:listDetails]  
    JasperReportDef rep = jasperService.buildReportDefinition(params,request.locale,result) 
    ByteArrayOutputStream stream = jasperService.generateReport(rep) 
    response.setHeader("Content-disposition", "attachment; filename=" + 'transaction' + ".pdf") 
    response.contentType = "application/pdf" 
    response.outputStream << stream.toByteArray() 
} 

Я могу отправить один элемент данных в Jasper Но я хочу отправить список данных с контроллера.

домен в порядке, но в вашем контроллере вы можете попробовать:

def jasperService 
     def jasperdata = { User -> user 
      List<User> listPhoneNumber = User.list() as Object[] 
      JasperReportDef rep = jasperService.buildReportDefinition(params,request.locale,[data:listPhoneNumber]) 
      ByteArrayOutputStream stream = jasperService.generateReport(rep) 

      response.setHeader("Content-disposition", "attachment; filename=" + 'transaction' + ".pdf") 
      response.contentType = "application/pdf" 
      response.outputStream << stream.toByteArray() 
      response.outputStream.flush() 
     } 

Посмотреть вы можете попробовать тоже:

<g:jasperReport action="profile" controller="jasperdata" format="PDF" jasper="listPhone"> 
</g:jasperReport> 

И в listPhone.jrxml, только для простого теста.
