Java Jasper报告中的多个文件

我使用以下代码在Jasper中调用我的jrxml文件：

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

import net.sf.jasperreports.engine.JREmptyDataSource;
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 Jasperreports {

    public static void main(String[] args) {
        Connection conn = null;
        String iphost = "myhostip";
        String dbsid = "DISAD";
        String username = "MYUSERNAME";
        String password = "mypassword";
        try {
            Class.forName("oracle.jdbc.driver.OracleDriver");
            conn = DriverManager.getConnection("jdbc:oracle:thin:@" + iphost + ":1521:" + dbsid, username, password);
            int count = 0;
            JasperReport jasperReport = JasperCompileManager.compileReport("Advice2.jrxml");
            JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, new HashMap(), conn);
            JasperExportManager.exportReportToPdfFile(jasperPrint, "sample" + count + ".pdf");
            count++;
        } catch (Exception e) {
            System.out.println(e);
        }
    }
}

我的jrxml文件是：

我只得到一个包含所有记录的.pdf文件。如何才能为每个记录生成一个文件，以便为每个报告生成不同的文件？

这只是JasperReports的标准行为。每个SQL查询返回的记录都会重复一次细节栏

因此，如果您想将每条记录保存在不同的PDF文件中，您有两个选项：

更改SQL查询，使其仅返回一条记录，并使用参数进行控制

获取java中SQL查询的数据，并将该信息作为参数或使用java对象数据集传递给JasperReport。它很老了，但展示了如何做

当然，对于这两种方法，您需要遍历记录，每个记录生成一个调用

希望有帮助
