Jasper Report使用Hibernate註釋導出PDF

我試圖從jasperReport庫中生成PDF。Jasper Report使用Hibernate註釋導出PDF

我嘗試了一些代碼，但它只生成了一些垃圾數值或測試字符串，我已經設置了測試的PDF。我的PDF這個樣子

空空（ID：空）空

這是共1頁演示

這裏是我的採購類代碼

您使用的是哪個版本的jasper報告？ – user1791574

JasperReports的-5.5.1 –

試試這個代碼：

package org.chillies.reports; 
import java.io.File; 
import java.util.HashMap; 
import net.sf.jasperreports.engine.JREmptyDataSource; 
import net.sf.jasperreports.engine.JRException; 
import net.sf.jasperreports.engine.JasperCompileManager; 
import net.sf.jasperreports.engine.JasperExportManager; 
import net.sf.jasperreports.engine.JasperFillManager; 
import net.sf.jasperreports.engine.JasperPrint; 
import net.sf.jasperreports.engine.JasperReport; 
public class JasperReportsIntro { 
public static void main(String[] args) { 
Purchase purchase = new Purchase(); 
    purchase.setName("Vivek"); 
    purchase.setRemark("This is remark"); 
    purchase.setDiscount(10.0); 
    purchase.setId(20); 
ArrayList<Purchase> list = new ArrayList<Purchase>(); 
     list.add(purchase); 
     JRDataSource beanCollectionDataSource = new JRBeanCollectionDataSource(list); 
JasperReport jasperReport; 
JasperPrint jasperPrint; 
try { 
    jasperReport = JasperCompileManager.compileReport("jrxmls" 
      + File.separator + "PurchaseReport.jrxml"); 
    jasperPrint = JasperFillManager.fillReport(jasperReport, new HashMap(), beanCollectionDataSource); 
    JasperExportManager.exportReportToPdfFile(jasperPrint, 
      "Genratedreports/simple_report.pdf"); 
    System.out.println("Completed"); 
} catch (JRException e) { 
    e.printStackTrace(); 
    } 
} 
}

享受。 :)

非常感謝你的回答，我也發現了這一切，我需要做的一個解決方案是隻是傳遞一個Hibernate會話像這樣---> \t \t \t會話= HibernateUtil.getSessionFactory（） .openSession（）; \t \t \t Map model = new HashMap （）; \t \t \t model.put（JRHibernateQueryExecuterFactory.PARAMETER_HIBERNATE_SESSION，session）; jasperFillManager.fillReport（jasperReport，model）; jsperPrint = JasperFillManager.fillReport（jasperReport，model）; \t \t \t JasperExportManager.exportReportToPdfFile（jasperPrint，「Genratedreports/simple_report1.pdf」）; –

這很好，你已經解決了它在你自己的一端。如果我的答案工作正常，你能接受並贊成嗎？ – user1791574

是的，謝謝你的朋友，你的代碼也在工作:)）但是你必須改變這樣的一行列表 list = new ArrayList （）; –
