JRFileVirtualizer를 사용하여 JasperReport를 사용하여 큰 xlsx 파일을 내보내는 방법은 무엇입니까? 나는 몇 가지 예제 코드는JRFileVirtualizer 및 JRXlsxExporter

전에 당신이 다음 행 당신의 코드 : 당신이 the Javadoc of the JRFileVirtualizer constructor을 살펴 경우 버츄얼가 CREA에 어디

  String report = "C://jsreport/Binding/PaymentPremiControlExcel.jasper"; 
... 
      JRFileVirtualizer jRFileVirtualizer = new JRFileVirtualizer(1000, report);

, 당신은 두 번째 인수는 폴더의 경로가 될 것을 볼 수 있습니다 임시 파일. 컴파일 된 보고서는 경로가 아니므로 폴더가 아닙니다 (오류가 발생할 때). "C://temp" 또는 가상화 프로그램이 임시 파일을 만들 수있는 경로를 입력하십시오.

을 사용하는 몇 가지 샘플이 있습니다. 그것이 그 문제의 근원인지 궁금합니다. 나중에 다시 시도하고 즉시 결과를 업데이트하겠습니다. 그것을 지적 주셔서 감사합니다. –
