Jasper Report 作为老牌的报表导出工具，其客户端 Jaspersoft Studio 支持可视化创建导出模板，让不懂开发的业务人员也能够作出一张漂亮的报表，极大地降低了上手难度。本文将介绍在 Spring boot 中集成 Jasper Report 导出 PDF 的功能。

2 核心 Maven 依赖
./demo-common/pom.xml<!-- jasper report -->

</dependency>其中 ${jasper-report.version} 的版本为 6.16.0
${itext.version} 的版本为 2.1.7
${google.zxing.version} 的版本为 3.4.1
简要说明:
jasperreports 为 jasper report 的核心导出依赖
jasperreports-fonts 为 jasper report 的字体拓展依赖，引入该 jar 可以自定义添加第三方字体
iText 是用于渲染导出 PDF 的依赖，pasperreport 中的 iText 版本为 2.1.7.js8,该版本在 Maven 仓库中不存在，因此需要使用 Maven 仓库中有的版本
google.zxing 为谷歌的二维码生成依赖
3 核心代码
3.1 PDF 导出工具类
./demo-common/src/main/java/com/ljq/demo/springboot/common/util/JasperPdfUtil.javapackage com.ljq.demo.springboot.common.util;
import cn.hutool.core.io.resource.ResourceUtil;
import net.sf.jasperreports.engine.*;
import net.sf.jasperreports.engine.util.JRLoader;
import java.io.FileNotFoundException;
import java.util.Map;
/**
* @Description: jasper 导出工具类
* @Author: junqiang.lu
* @Date: 2021/2/4
*/
public class JasperPdfUtil {
private JasperPdfUtil(){
}
/**
* 导出 PDF
*
* @param templatePath jrxml 模板路径(base classpath)
* @param paramMap 数据对象
* @return
* @throws FileNotFoundException
* @throws JRException
*/
public static byte[] exportPdfFromXml(String templatePath, Map<String, Object> paramMap) throws FileNotFoundException, JRException {
JasperReport jasperReport = getJasperReportFromXml(templatePath);
JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, paramMap, new JREmptyDataSource());
return JasperExportManager.exportReportToPdf(jasperPrint);
}
/**
* 导出 PDF
*
* @param templatePath jasper 模板路径(base classpath)
* @param paramMap 数据对象
* @return
* @throws FileNotFoundException
* @throws JRException
*/
public static byte[] exportPdfFromJasper(String templatePath, Map<String, Object> paramMap) throws FileNotFoundException, JRException {
JasperReport jasperReport = getJasperReportFromJasper(templatePath);
JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, paramMap, new JREmptyDataSource());
return JasperExportManager.exportReportToPdf(jasperPrint);
}
/**
* 获取导出对象,从 xml 中
*
* @param templatePath 模板路径(base classpath)
* @return
* @throws FileNotFoundException
* @throws JRException
*/
private static JasperReport getJasperReportFromXml(String templatePath) throws FileNotFoundException, JRException {
return JasperCompileManager.compileReport(ResourceUtil.getStream(templatePath));
}
/**
* 获取导出对象,从 jasper 中
* (jasper 为 jrxml 编译后生成的文件)
*
* @param templatePath 模板路径(base classpath)
* @return
* @throws FileNotFoundException
* @throws JRException
*/
private static JasperReport getJasperReportFromJasper(String templatePath) throws FileNotFoundException, JRException {
return (JasperReport) JRLoader.loadObject(ResourceUtil.getStream(templatePath));
}
}注意事项:
Jaspert Report 的导出工具类不建议使用数据源，在 SpringBoot 项目中数据源统一由 Spring 管理。但是即使没有数据源也要传一个 new JREmptyDataSource() 来作为参数，否则如果使用 net.sf.jasperreports.engine.JasperFillManager#fillReport(net.sf.jasperreports.engine.JasperReport, java.util.Map<java.lang.String,java.lang.Object>) 方法，会抛异常

字体文件
./demo-web/src/main/resources/static/font/stsong.ttf字体配置文件
./demo-web/src/main/resources/static/font/fonts.xml<?xml version="1.0" encoding="UTF-8"?>
<fontFamilies>
<fontFamily name="华文宋体">
<normal>static/font/stsong.ttf</normal>
<bold>static/font/stsong.ttf</bold>
<italic>static/font/stsong.ttf</italic>
<boldItalic>static/font/stsong.ttf</boldItalic>
<pdfEncoding>Identity-H</pdfEncoding>
<pdfEmbedded>true</pdfEmbedded>
<exportFonts>
<export key="net.sf.jasperreports.html">'华文宋体', Arial, Helvetica, sans-serif</export>
<export key="net.sf.jasperreports.xhtml">'华文宋体', Arial, Helvetica, sans-serif</export>
</exportFonts>
</fontFamily>
</fontFamilies>Jasper 拓展拓展配置，在项目运行时会加载该信息
./demo-web/src/main/resources/jasperreports_extension.propertiesnet.sf.jasperreports.extension.registry.factory.simple.font.families=net.sf.jasperreports.engine.fonts.SimpleFontExtensionsRegistryFactory
net.sf.jasperreports.extension.simple.font.families.lobstertwo=static/font/fonts.xmlJaper jrxml 模板中的字体必须与fonts.xml 中配置的字体名称保持一致才会生效
3.4 二维码设置
在 Jaspersoft Studio 中拖拽一个「Image」标签至布局界面，设置图片的「Expression」表达式属性
表达式为:
com.google.zxing.client.j2se.MatrixToImageWriter.toBufferedImage(
new com.google.zxing.qrcode.QRCodeWriter().encode(
$P{contractCode},
com.google.zxing.BarcodeFormat.QR_CODE, 300, 300))其中 $P{contractCode} 即为所需要生成二维码的参数
