JasperReports：如何在JSP页面中显示报表？
如何在JSP页面中显示jasper报告？ 我正在使用iReport 1.3.3工具来创build报告。
我能够创build报告，但我正努力在JSP页面中显示该报告。
注意：我需要以PDF和Excel格式显示报告。
也许我可以给你一个select你的问题。 我给你这个例子。
package reports; /** * * @author felix */ @javax.servlet.annotation.WebServlet(name="Reports", urlPatterns={"/reports"}) public class HtmlReportServlet extends javax.servlet.http.HttpServlet { //public static final String REPORT_DIRECTORY = "/reports"; @Override protected void doGet(javax.servlet.http.HttpServletRequest request, javax.servlet.http.HttpServletResponse response) throws javax.servlet.ServletException, java.io.IOException { //javax.servlet.ServletContext context = this.getServletConfig().getServletContext(); java.io.InputStream reportSource = getClass().getResourceAsStream("/jrmain/test.jasper"); java.util.Map<String, Object> params = new java.util.HashMap<String, Object>(); org.apache.log4j.Logger logger = org.apache.log4j.Logger.getRootLogger(); logger.setLevel((org.apache.log4j.Level)org.apache.log4j.Level.WARN); java.io.PrintWriter printWriter = response.getWriter(); try { net.sf.jasperreports.engine.JasperPrint jasperPrint = net.sf.jasperreports.engine.JasperFillManager.fillReport(reportSource, params, new apps.dbase.DBaseLink().OpenLink()); net.sf.jasperreports.engine.export.JRHtmlExporter htmlExporter = new net.sf.jasperreports.engine.export.JRHtmlExporter(); response.setContentType("text/html"); request.getSession().setAttribute(net.sf.jasperreports.j2ee.servlets.ImageServlet.DEFAULT_JASPER_PRINT_SESSION_ATTRIBUTE, jasperPrint); htmlExporter.setParameter(net.sf.jasperreports.engine.JRExporterParameter.JASPER_PRINT, jasperPrint); htmlExporter.setParameter(net.sf.jasperreports.engine.JRExporterParameter.OUTPUT_WRITER, printWriter); htmlExporter.setParameter(net.sf.jasperreports.engine.export.JRHtmlExporterParameter.IMAGES_URI, "image?image="); htmlExporter.exportReport(); printWriter.close(); } catch (Exception e) { // display stack trace in the browser e.printStackTrace(printWriter); } } }
