本文详细介绍了一个使用Java生成PDF格式报表的具体实例，通过操作jrxml文件并填充数据，最终利用JasperReports库完成报表的生成与导出。

话不多说，直接上代码：

    @RequestMapping("/demo01")
    public void test(HttpServletRequest request, HttpServletResponse response) {

        try{
            Map<String, Object> paramsMap = new HashMap<>();
            File logoFile = ResourceUtils.getFile("classpath:static/img/logo.jpg");
            paramsMap.put("logUrl",logoFile.getAbsolutePath());
            List<ApplyForEvaluation> listObj = new ArrayList<>();
            ApplyForEvaluation obj = new ApplyForEvaluation();
            obj.setEvaluateCode("1112845857174");
            obj.setHouseOwner("张三");
            obj.setPropertyNo("1234567890");
            obj.setHouseAddress("1号楼2单元602室");
            obj.setSystemAddress("1号楼2单元602室");
            obj.setBuildingStructure("混凝土");
            obj.setCurrentFloor(12);
            obj.setTotalFloor(33);
            obj.setBuildingArea(189.43);
            obj.setHouseUse("住房");
            obj.setBuildingYear(2001);
            obj.setEvaluateDate("2018年9月3日");
            obj.setUnitPrice(170000);
            obj.setTotalPrice(604.38);
            listObj.add(obj);
            String fileName = "E:\\iReportDemo\\applyForEvaluate.jrxml";//直接操作生成的jrxml文件
            JasperReport jasperReport = JasperCompileManager.compileReport(fileName);//编译jrxml文件
            JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, paramsMap, new JRBeanCollectionDataSource(listObj));
            //设定输出格式
            OutputStream ouputStream = response.getOutputStream();
            response.setContentType("application/pdf");
            response.setCharacterEncoding("UTF-8");
            response.setHeader("Content-Disposition", "attachment; filename=" + URLEncoder.encode(obj.getEvaluateCode(), "UTF-8") + ".pdf");
            // 使用JRPdfExproter导出器导出pdf
            JRPdfExporter exporter = new JRPdfExporter();
            exporter.setExporterInput(new SimpleExporterInput(jasperPrint));
            exporter.setExporterOutput(new SimpleOutputStreamExporterOutput(ouputStream));
            SimplePdfExporterConfiguration configuration = new SimplePdfExporterConfiguration();
            exporter.setConfiguration(configuration);
            exporter.exportReport();
        }catch (Exception e){
            e.printStackTrace();
        }
