2019-05-09 EasyWeb下使用JasperReport制作主从表

【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         <dependency>
14             <groupId>com.google.zxing</groupId>
15             <artifactId>core</artifactId>
16             <version>3.3.3</version>
17         </dependency>
18         <dependency>
19             <groupId>com.google.zxing</groupId>
20             <artifactId>javase</artifactId>
21             <version>3.3.3</version>
22         </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

76         </band>

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     }

【最终效果】
