我在这段代码中使用 JasperReport。

import net.sf.jasperreports.engine.JRException;
import net.sf.jasperreports.engine.JasperCompileManager;
import net.sf.jasperreports.engine.JasperFillManager;
import net.sf.jasperreports.engine.JasperPrint;
import net.sf.jasperreports.engine.JasperReport;
import net.sf.jasperreports.engine.design.JRDesignQuery;
import net.sf.jasperreports.engine.design.JasperDesign;
import net.sf.jasperreports.engine.xml.JRXmlLoader;
import net.sf.jasperreports.view.JasperViewer;

    public void printData(String report , String printQuery){
        try{
            jasperDesign = JRXmlLoader.load(report);
            query.setText(printQuery);
            jasperDesign.setQuery(query);
            jr = JasperCompileManager.compileReport(jasperDesign);
            jp = JasperFillManager.fillReport(jr,null, databaseHandler.getConnection());
            JasperViewer.viewReport(jp,false);

        }catch (JRException ex) {
            AlertMaker.showException("Exception Occurred ! " , ex.toString());
        }
    }

谁能帮我告诉java项目中需要包含哪些jar库文件？因为包括JasperReport的所有jar文件降低项目性能(这些jar lib文件超过60个)

Answer 1

基本上，这些是强制性的 jar，其余的您可以根据您的要求添加。
