commons-logging-1.0.2.jar;commons-logging-api-1.0.2.jar;itext-1.3.1.jar;
jasperreports-1.3.3.jar;jdt-compiler-3.1.1.jar;jxl-2.6.jar;png-encoder-1.5.jar;poi-2.0-final-20040126.jar
一、导出报表到html
InputStream inputStream = ServletActionContext.getServletContext().getResourceAsStream("/report/xxx.jasper");Collection<xxxo> data=xxxService.getData(params);Map<Object,Object> map=xxxService.getMap(startTime, endTime);JRBeanCollectionDataSource dataSource=new JRBeanCollectionDataSource(data);//填充报表JasperPrint jasperPrint = JasperFillManager.fillReport(inputStream,map, dataSource);//设置输出类型及报表的内置参数response.setContentType("text/html");OutputStream outputStream=response.getOutputStream();ReportXHtmlExporter htmlExporter=new ReportXHtmlExporter(page,jasperPrint);request.getSession().setAttribute(ImageServlet.DEFAULT_JASPER_PRINT_SESSION_ATTRIBUTE,jasperPrint);htmlExporter.setParameter(JRExporterParameter.JASPER_PRINT,jasperPrint);htmlExporter.setParameter(JRExporterParameter.OUTPUT_STREAM, outputStream);if(jasperPrint.getPages().size()>1){htmlExporter.setParameter(JRExporterParameter.PAGE_INDEX, 1);}htmlExporter.setParameter(JRHtmlExporterParameter.IS_USING_IMAGES_TO_ALIGN,Boolean.FALSE);htmlExporter.exportReport();outputStream.flush();outputStream.close(); 二、导出到PDF
OutputStream outputStream=response.getOutputStream();File reportFile = new File(ServletActionContext.getServletContext().getRealPath("/report/xxx.jasper"));if (!reportFile.exists()){throw new JRRuntimeException("File dispatch_report.jasper not found.");}JasperReport jasperReport = (JasperReport)JRLoader.loadObject(reportFile.getPath());//javabean数据源Collection<xxx> data=xxxService.getData(params);Map<Object,Object> map=xxxService.getMap(startTime, endTime);JRBeanCollectionDataSource dataSource=new JRBeanCollectionDataSource(data);JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport,map, dataSource);JRPdfExporter pdfExporter=new JRPdfExporter();pdfExporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);pdfExporter.setParameter(JRExporterParameter.OUTPUT_STREAM, outputStream); response.setContentType("application/pdf");response.setCharacterEncoding("UTF-8");response.setHeader("Content-Disposition", "attachment; filename=\""+ URLEncoder.encode("XXX报表", "UTF-8") + ".pdf\""); pdfExporter.exportReport();outputStream.flush();outputStream.close(); 三、web.xml配置
<!--JasperReport显示图片的,象素图片--><servlet><servlet-name>ImageServlet</servlet-name><servlet-class>net.sf.jasperreports.j2ee.servlets.ImageServlet</servlet-class></servlet><servlet-mapping><servlet-name>ImageServlet</servlet-name><!-- /report/image路径,report表示struts中的表空间(具体就看url请求的路径),image表示Action文件里配置image?image=问号前的image相同--><url-pattern>/report/image</url-pattern></servlet-mapping>
