PDF-使用中文注意事项

      jasper在使用中文时,需要选择对应的字体,并在java的项目中做对应的配置;使用的文字是根据[ 系统盘:windows/fount目录下的字体,并且是ttf格式的字体 ]

• 项目的resources目录下

  • fonts.xml [配置文件]

    <?xml version="1.0" encoding="UTF-8"?>
    
    <fontFamilies>
        <fontFamily name="华文宋体">
            <normal>stsong/stsong.TTF</normal>
            <bold>stsong/stsong.TTF</bold>
            <italic>stsong/stsong.TTF</italic>
            <boldItalic>stsong/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>
    

  • 使用的字体 [模板要用到的字体,可以在网上下载或从字体文件拷贝到项目中]

  • jasper配置文件

    jasperreports_extension.properties

    net.sf.jasperreports.extension.registry.factory.simple.font.families=net.sf.jasperreports.engine.fonts.SimpleFontExtensionsRegistryFactory
    net.sf.jasperreports.extension.simple.font.families.lobstertwo=fonts.xml

Java整合Jasper

• 需要的jar包

<dependency>
	<groupId>net.sf.jasperreports</groupId>
	<artifactId>jasperreports</artifactId>
	<version>6.5.0</version>
</dependency>
<dependency>
	<groupId>org.olap4j</groupId>
	<artifactId>olap4j</artifactId>
	<version>1.2.0</version>
</dependency>
<dependency>
	<groupId>com.lowagie</groupId>
	<artifactId>itext</artifactId>
	<version>2.1.7</version>
</dependency>

• 核心代码

 public void exportPdf() throws Exception {
        //1.读取.jasper模板文件
        InputStream inputStream = session.getServletContext().getResourceAsStream("/jasper/test04_javabean.jasper");

        //2.填充数据
        List<User> list = new ArrayList<>();
     	Map map = new HashMap();
        JRBeanCollectionDataSource dataSource = new JRBeanCollectionDataSource(list);
        JasperPrint print = JasperFillManager.fillReport(inputStream , map , dataSource);

        //3.导出PDF
        /**
         * 参数一：JasperPrint对象
         * 参数二：输出流（硬盘或浏览器）
         */
        JasperExportManager.exportReportToPdfStream(print,response.getOutputStream());
    }
