JasperReports-보고서 내보내기
이전 장에서 JasperReport 생성 문서를 인쇄하고 보는 방법을 살펴 보았습니다. 여기서는 이러한 보고서를 PDF, HTML 및 XLS와 같은 다른 형식으로 변환하거나 내보내는 방법을 살펴 보겠습니다. 이 기능을 구현하기 위해 Facade 클래스 net.sf.jasperreports.engine.JasperExportManager 가 제공됩니다. 변화시키는 수단 내보내기 JasperPrint의 다른 포맷으로 객체 (.jrprint 파일).
다음 코드 (JasperReportExport.java)는 JasperReport 문서의 내보내기 프로세스를 보여줍니다. JasperExportManager는 보고서를 PDF, HTML 및 XML로만 내보내는 방법을 제공합니다. XLS 형식으로 내보내기 위해 net.sf.jasperreports.engine.export.JRXlsExporter 클래스를 사용했습니다 . 이 코드는 다음 세 파일을 생성합니다.
- sample_report.pdf
- sample_report.html
- sample_report.xls
다른 형식으로 내보내기
보고서 템플릿을 작성해 보겠습니다. JRXML 파일 (C : \ tools \ jasperreports-5.0.1 \ test \ jasper_report_template.jrxml)의 내용은 다음과 같습니다.

메인 클래스 파일 작성 JasperReportFill.java, 클래스 (DataBeanList)에서 Java Bean 컬렉션을 가져 와서이를 JasperReports 엔진에 전달하여 보고서 템플릿을 채 웁니다. 디렉토리에 저장C:\tools\jasperreports-5.0.1\test\src\com\tutorialspoint.

일반적인 ANT 빌드 프로세스를 사용하여 위의 파일을 컴파일하고 실행 해 보겠습니다. build.xml 파일은 다음과 같습니다.
<?xml version = "1.0" encoding = "UTF-8"?>
<project name = "JasperReportTest" default = "executereport" basedir = ".">
<import file = "baseBuild.xml"/>
<target name = "executereport" depends = "compile,compilereportdesing,run">
