java - Jasper 报告中的多个文件

Question

我正在使用此代码在 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：

我得到一个包含所有记录的文件 .pdf。如何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？

score 1 · Accepted Answer

这只是 JasperReports 的标准行为。每条 SQL 查询返回的记录，详细信息带将重复一次。

因此，如果您希望将每条记录放在不同的 PDF 文件中，您有两种选择：

更改您的 SQL 查询，使其仅返回一条记录，使用参数，以便您可以控制它。
在 java 中获取 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。这个例子很老，但展示了如何去做。

当然，您需要遍历记录，为这两种方法的每条记录生成一个调用。

希望有帮助
