jasperreport生成简单的报表

来源：互联网发布：mac版本的office 编辑：程序博客网时间：2024/05/16 15:01

1、建立jrxml文件。

.jrxml是XML文件类型。可以用Ireport自动生成。也可以自己写一个。

2、对 .jrxml文件转成.jasper文件。

JasperCompileManager.compileReportToFile("d:/reports/"+fileName+".jrxml");

3、把.jasper文件转成PDF文件

JasperRunManager.runReportToPdfFile("d:/reports/"+fileName+".jasper","d:/reports/"+fileName+".pdf",new HashMap(), new JREmptyDataSource());

这只是一个简单的报表，想要更复杂的还可以在里面加入元素。

这样完成任务：）

程序：

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.JasperFillManager;
import net.sf.jasperreports.engine.JasperRunManager;

public class Pdf
{

public static void main(String []arg)
{
     try
     {
     String fileName="FirstReport";
     System.out.println("Starting...");
     JasperCompileManager.compileReportToFile("d:/reports/"+fileName+".jrxml");
      JasperRunManager.runReportToPdfFile("d:/reports/"+fileName+".jasper","d:/reports/"+fileName+".pdf",new HashMap(), new JREmptyDataSource());
     System.out.println("Done...");
     }
     catch (JRException e)
     {
       e.printStackTrace();
     }
}
}

jrxml:
