如何將.jasper文件反編譯爲.jrxml文件

Question

我丟失了我所有的.jrxml文件，但我有.jasper文件。我可以反編譯。jasper文件到.jrxml文件嗎？如果是的話，那對我來說會很有幫助。

Answer 1

* .jasper文件可以直接從ireport打開，Ireport自動反編譯文件。

Answer 2

import net.sf.jasperreports.engine.JRException; 
import net.sf.jasperreports.engine.util.JRLoader; 
import net.sf.jasperreports.engine.xml.JRXmlWriter; 
import net.sf.jasperreports.engine.JasperReport; 

class JasperToXml { 

    public static String sourcePath; 
    public static String destinationPath; 

    public static void main(String[] args) { 
     sourcePath = "..File1.jasper"; 
     destinationPath = "...File2.jrxml"; 

     JasperReport report = (JasperReport) JRLoader.loadObject(sourcePath); 
     JRXmlWriter.writeReport(report, destinationPath, "UTF-8"); 
    } 
}
