用JasperReport来生成html报表，为什么没反应

Answer 1

您好，很高兴为您解答：

String contextPath=request.getContextPath();
String fileName="C:/Program Files/Apache Software Foundation/Tomcat 5.0/webapps/Jasper/reports/AircraftReport.jasper";
String outFileName="C:/Program Files/Apache Software Foundation/Tomcat 5.0/webapps/Jasper/reports/AircraftReport.html";
//String outFileName="reports/AircraftReport.pdf";
try{

JRDataSource dataSource = createReportDataSource();
JasperPrint print=JasperFillManager.fillReport(fileName,new HashMap(),dataSource);
//JRExporter exporter=new JRPdfExporter();
JRExporter exporter=new JRHtmlExporter();
exporter.setParameter(JRExporterParameter.OUTPUT_FILE_NAME, outFileName);
exporter.setParameter(JRExporterParameter.JASPER_PRINT,print);
exporter.exportReport();

}catch(Exception e){
e.printStackTrace();
}
