Spring MVC结合ireport采用javabean作为数据源的实现

这段时间一直在研究ireport如何和springmvc结合来实现报表的显示

网上查了很多资料，从各位前辈们的经验下结合自己的心得总结了SpringMVC结合ireport采用javabean作为数据源的实现方式，并总结代码如下：

Ireport采用javabean作为数据源实现数据的载入，对于java中，使用得到的list集合封装到JRBeanCollectionDataSource中来得到数据。最后通过JRHtmlExporter将结果展现给用户。

输出为html格式的设计方案：

@RequestMapping("/customer/reporthtml.do")  
        public void report(HttpServletRequest request, HttpServletResponse response)  
                throws IOException, JRException {  
            String ctxpath = request.getSession().getServletContext()  
                    .getRealPath("/report/beandata.jasper");          
            List<HKCustomer> listInfo = this.hkCustomerService.listAllCustomers();  
            File reFile = new File(ctxpath);  
            Map parameters = new HashMap();//根据变量来查询      
            JRBeanCollectionDataSource ds = new JRBeanCollectionDataSource(listInfo);  
            JasperPrint jasperPrint = JasperFillManager.fillReport(  
                    reFile.getPath(), parameters, ds);  
              
            JRHtmlExporter exporter = new JRHtmlExporter();       
            //输出为html格式的报表文件  
            exporter.setParameter(JRHtmlExporterParameter.JASPER_PRINT, jasperPrint);  
            exporter.setParameter(JRHtmlExporterParameter.OUTPUT_STREAM,response.getOutputStream());       exporter.setParameter(JRHtmlExporterParameter.IS_USING_IMAGES_TO_ALIGN,Boolean.FALSE);  
          //移除设计报表中的空白行 exporter.setParameter(JRHtmlExporterParameter.IS_REMOVE_EMPTY_SPACE_BETWEEN_ROWS, Boolean.TRUE);  
           exporter.setParameter(JRHtmlExporterParameter.CHARACTER_ENCODING, "utf-8");  
              exporter.exportReport();  
        }

输出为execl表格格式

@RequestMapping("/customer/reportxls.do")  
    public void exportxls(HttpServletRequest request,  
            HttpServletResponse response) throws IOException, JRException {  
        String ctxpath = request.getSession().getServletContext()  
                .getRealPath("/report/beandata.jasper");          
        List<HKCustomer> listInfo = this.hkCustomerService.listAllCustomers();  
        File reFile = new File(ctxpath);  
        Map parameters = new HashMap();       
        JRBeanCollectionDataSource ds = new JRBeanCollectionDataSource(listInfo);  
        JasperPrint jasperPrint = JasperFillManager.fillReport(  
                reFile.getPath(), parameters, ds);    
        JRXlsExporter exporter=new JRXlsExporter();       
        exporter.setParameter(JRXlsExporterParameter.JASPER_PRINT, jasperPrint);  
        exporter.setParameter(JRXlsExporterParameter.OUTPUT_STREAM, response.getOutputStream());  
        exporter.setParameter(JRXlsExporterParameter.IS_ONE_PAGE_PER_SHEET, Boolean.FALSE);
exporter.setParameter(JRXlsExporterParameter.IS_REMOVE_EMPTY_SPACE_BETWEEN_ROWS, Boolean.TRUE);  
/设置输出的格式  
response.setHeader("Content-Disposition", "attachment;filename=customer.xls");  
response.setContentType("application/vnd_ms-excel");  
exporter.exportReport();

设置输出为Pdf格式的文件

@RequestMapping("/customer/reportpdf.do")  
  
         publicvoid exportpdf(HttpServletRequest request,HttpServletResponse response) throwsJRException, IOException{  
  
                   Stringctxpath = request.getSession().getServletContext()  
  
                                     .getRealPath("/report/beandata.jasper");                
  
                   List<HKCustomer>listInfo = this.hkCustomerService.listAllCustomers();  
  
                   FilereFile = new File(ctxpath);  
  
                   Mapparameters = new HashMap();                  
  
                   JRBeanCollectionDataSourceds = new JRBeanCollectionDataSource(listInfo);  
  
                   JasperPrintjasperPrint = JasperFillManager.fillReport(  
  
                                     reFile.getPath(),parameters, ds);             
  
                   JRPdfExporterexporter = new JRPdfExporter();       
  
                   exporter.setParameter(JRPdfExporterParameter.JASPER_PRINT,jasperPrint);  
  
                   exporter.setParameter(JRPdfExporterParameter.OUTPUT_STREAM,response.getOutputStream());  
  
                   response.setHeader("Content-Disposition","attachment;filename=customer.pdf");  
  
                   response.setContentType("application/pdf");  
  
                   response.setCharacterEncoding("utf-8");  
  
                   exporter.exportReport();  
  
         }
