 步骤:

一、Controller

 1     @GetMapping(value = {"/printlabel"})
 2 //    @RequiresPermissions("biz:container:print")
 3     public void printlabel(@RequestParam(value = "ids") String ids, HttpServletResponse response) throws Exception {
 4         try {
 5             List list=new ArrayList();
 6             Long[] idArr= Convert.toLongArray(ids);
 7             for(long id:idArr){
 8                 BizContainer container = containerService.selectContainerById(id);
 9                 if (container.getContainerType().equalsIgnoreCase("B")){
10                     if (container.getPrintContent()!=null&&container.getPrintContent().indexOf("/")>0){
11                         String[] strArr=StringUtils.split(container.getPrintContent(),"/");
12                         String strs="";
13                         for(String str:strArr){
14                             strs+=str+"\r\n\r\n";
15                         }
16                         container.setPrintContent(strs);
17                     }
18                     list.add(container);
19                 }
20             }
21 
22             //输出到文件
23 //            File f = new File("d://test.pdf");
24 //            OutputStream out = new FileOutputStream(f);
25 //            preview(columns, list, out);
26 //            out.close();
27 //            logger.info("成功~");
28 
29             //输出到前端
30             response.setContentType("application/pdf");
31             response.setHeader("Content-Disposition", "inline;");
32             final OutputStream outputStream = response.getOutputStream();
33             preview(list, outputStream);
34         } catch (Exception e) {
35             // TODO Auto-generated catch block
36             e.printStackTrace();
37         }
38     }

二、报表代码部分

1、

   /**
     * PDF打印
     *
     * @param list    数据来源
     * @param out     輸出流
     * @throws Exception
     */
    public static void preview(List list,
                               OutputStream out) throws Exception {
        JasperReport jp = getJasperReport();

        Map parameters = new HashMap();
        JasperPrint jasperPrint = JasperFillManager.fillReport(jp, parameters,
                new JRBeanCollectionDataSource(list));

        JasperExportManager.exportReportToPdfStream(jasperPrint, out);
    }

2、

    /**
     * 生成JasperReport对象
     *
     * @return
     * @throws JRException
     */
    @SuppressWarnings("deprecation")

        /**
         * 定义尺寸
         */

        final int pageWidth=595;//页面宽度

        final int textWidth=rectWidth;//文字宽度
