賈斯珀子報告

Question

與此掙扎了一週，是的，我感謝以前的帖子在同一主題上略有進展，但不完全。

兩個報告：

Master Report - Contains company info 
Sub Report - Contains 1..* company orders in detail list 

的數據源是從POJO數組列表內置：

主報告：

化java我使用com的代碼樁和打印報告在運行時：

CompanyMapper cm = new CompanyMapper();   
this.company = cm.getCompanyByID((Long) httpRequest.getSession().getAttribute("userCompanyID")); 
List<ACompany> c = new ArrayList<ACompany>(); 
List<AOrder> companyOrders = getOrders(getParameterInt("orderStatus")); 

c.add(this.company); 

String reportFolder = httpRequest.getServletContext().getRealPath("/").replace('\\', '/') + "reports/";   
String invoice = reportFolder + ReportManager.getProperty("orders");    
String orders = reportFolder + ReportManager.getProperty("orderList"); 
File invoiceFile = new File(invoice); 
File orderFile = new File(orders); 
msgHelper = new MessageHelper();   

JasperReport jasperMasterReport = JasperCompileManager.compileReport(invoiceFile.getAbsolutePath()); 
JasperReport jasperSubReport = JasperCompileManager.compileReport(orderFile.getAbsolutePath()); 

Map<String,Object> parameters = new HashMap<String,Object>();      
parameters.put("SUB_REPORT", jasperSubReport); 
parameters.put("SUB_REPORT_DATA", new JRBeanCollectionDataSource(companyOrders)); 

JasperFillManager.fillReport(jasperSubReport, parameters, new JRBeanCollectionDataSource(companyOrders)); 
JasperPrint print = JasperFillManager.fillReport(jasperMasterReport, parameters, new JRBeanCollectionDataSource(c));    

公司信息顯示精細的主報告然而，在細節沒有訂單從子報表打印。當我打印子報表時，有數據（即訂單明細）按預期顯示。我只想在主人的詳細部分傳遞子報表，並且一切都將完美。

Answer 1

如果你想使用「companyOrders」作爲一個字段在報表中，你必須把它放在你的「ACompany」 POJO，或多或少這樣的：

public class DataBean { 
    private String companyName; 
    private List<AOrder> companyOrders; 
}
