Question

我正在尝试生成一个简单的密码保护的Excel报告。

Java代码：

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import java.util.HashMap;

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.export.JExcelApiExporter;
import net.sf.jasperreports.engine.export.JExcelApiExporterParameter;

public class Report {

    public static void main(String[] args) {
        try {
            JasperReport jasperReport;
            JasperPrint jasperPrint;

            Connection connection = establishConnection();
            HashMap jasperParameter = new HashMap();

            jasperReport = JasperCompileManager.compileReport("D:\\Jasper\\report1.jrxml");
            jasperPrint = JasperFillManager.fillReport(jasperReport, jasperParameter, connection);

            JExcelApiExporter exporter = new JExcelApiExporter();
            exporter.setParameter(JExcelApiExporterParameter.JASPER_PRINT, jasperPrint);
            exporter.setParameter(JExcelApiExporterParameter.OUTPUT_FILE_NAME, "D:\\Jasper\\simple_report.xls");
            exporter.setParameter(JExcelApiExporterParameter.PASSWORD, "sam");

            exporter.exportReport();
        } catch (JRException e) {
            e.printStackTrace();
        }
    }

    public static Connection establishConnection() {
        Connection connection = null;
        try {
            Class.forName("com.mysql.jdbc.Driver");
            String mySQL = "jdbc:mysql://localhost:3306/test";
            connection = DriverManager.getConnection(mySQL, "root", "Infy123+");
            connection.setAutoCommit(false);
        } catch (SQLException | ClassNotFoundException exception) {
            exception.printStackTrace();
        }
        return connection;
    }
}

report1.jrxml：

    </pageFooter>
    <summary>

    </summary>
</jasperReport>

文件已生成但未受密码保护。

我正在使用 JasperReports-5.5.0 和 iReport 5.5.0 。

如何解决此问题？

Answer 1

您可以使用JasperReport中提供的内置POI API禁用Excel报告的编辑。但是，excel仍然可以打开。

受密码保护仅适用于Excel编辑选项。

我也有兴趣知道是否有办法密码保护excel文档本身..在Apache POI中找不到任何东西。

如何使用JasperReports生成受密码保护的Excel报告？
