2019-05-09 EasyWeb下使用JasperReport制作主从表
作者：互联网
【制作思路】
一个报表模板只能放置一个数据源，当有两个及以上时候，需要使用主报表嵌套子报表；主报表使用数据源方式传入数据，子报表使用参数方式传入数据
【开发注意】
1.报表中使用了二维码，所以需要引入依赖，所有与报表相关的依赖如下
1 <dependency> 2 <groupId>net.sf.jasperreports</groupId> 3 <artifactId>jasperreports</artifactId> 4 <version>6.8.0</version> 5 </dependency> 6 7 <!-- jasperreport用到的二维码生成 --> 8 <dependency> 9 <groupId>net.sf.barcode4j</groupId> 10 <artifactId>barcode4j</artifactId> 11 <version>2.1</version> 12 </dependency> 13 <!-- jasperreport 宋体字符库 解决中文不显示 --> 14 <dependency> 15 <groupId>cn.lesper</groupId> 16 <artifactId>iTextAsian</artifactId> 17 <version>3.0</version> 18 </dependency>
2.需要在报表模板编辑器Parameters中定义存放从表数据的参数detailData
3.在报表模板编辑器中增加Subreport指向子报表模板
4.在Subreport属性中设置Data Source Expression（数据源表达式），通过java类转换成数据源传给子报表
1 new net.sf.jasperreports.engine.data.JRBeanCollectionDataSource($P{detailData})
【关键代码】
1.主报表模板

3.后端Java 代码
1 @RequestMapping("/report")
2 public void getReport(String orderID,HttpServletRequest request, HttpServletResponse response) throws Exception {
3 // 主表数据放入主报表模板渲染数据源
4 List<Object> list = new ArrayList<Object>();
5 ProductOrderExample example1 = new ProductOrderExample();
6 example1.createCriteria().andIdEqualTo(orderID);
7 list.add(productOrderService.list(example1, 1, 1).getData().get(0));
8
9
10 HashMap<String, Object> parameters = new HashMap<String, Object>();
11
12 // 从表数据放入主报表模板参数detailData
13 ProductOrderDetailExample example2 = new ProductOrderDetailExample();
14 example2.createCriteria().andOrderIDEqualTo(orderID);
15 parameters.put("detailData",productOrderDetailService.list(example2, 0, 0).getData());
16 // 设置报表标题参数
17 parameters.put("title","生产派工单");
18
19
20 JasperReportUtils.printPdf2HtmlByJavaBean(request, response, "classpath:jasper/demo1/order.jasper",parameters ,list );
21
22
23 }
4.上面涉及的printPdf2HtmlByJavaBean封装代码
1 /**
2 * 使用JavaBean填充打印PDF到Html中
3 * @param request
4 * @param response
5 * @param jasperPath 例如：classpath:jasper/report2.jasper
6 * @param list JavaBean数据
7 * @param parameters
8 * @throws Exception
9 */
10 public static void printPdf2HtmlByJavaBean(HttpServletRequest request, HttpServletResponse response,String jasperPath,Map<String, Object> parameters,List<?> list) throws Exception {
11
12 ServletOutputStream outputStream = response.getOutputStream();
13
14 //获取报表的编译文件，后面要将对其进行填充数据
15 String path = URLDecoder.decode(ResourceUtils.getURL(jasperPath).getPath(),"UTF-8");
16
17 FileInputStream inputStream =new FileInputStream(new File(path));
18
19 //由于没有数据，故这里使用空参数和空数据源，该方法需要抛出JRException异常
20 JasperRunManager.runReportToPdfStream(inputStream, outputStream, parameters , new JRBeanCollectionDataSource(list));
21
22 // 输出PDF
23 response.setContentType("application/pdf");
24
25 // 关闭资源
26 outputStream.flush();
27 outputStream.close();
28 inputStream.close();
29
30 }
