SpringBoot + JasperReport6.x 集成报表控件，导出PDF汉字无法显示，控制台提示如下错误信息：

WARN  net.sf.jasperreports.engine.export.PdfGlyphRenderer - Unpatched iText found, cannot use glyph rendering

SpringBoot 集成JasperReport6.x 之相关依赖：

指定JasperReport6.x 报表字体：

jasperreports\_extension.properties文件内容如下：

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

fonts.xml配置内容如下：

<?xml version="1.0" encoding="UTF-8"?>
    <fontFamilies>
        <fontFamily name="STS">
            <normal>fonts/STSONG.TTF</normal>
            <bold>fonts/STSONG.TTF</bold>
            <italic>fonts/STSONG.TTF</italic>
            <boldItalic>fonts/STSONG.TTF</boldItalic>
            <pdfEncoding>Identity-H</pdfEncoding>
            <pdfEmbedded>true</pdfEmbedded>
            <exportFonts>
                <export key="net.sf.jasperreports.html">STS, Arial, Helvetica, sans-serif</export>
                <export key="net.sf.jasperreports.xhtml">STS, Arial, Helvetica, sans-serif</export>
            </exportFonts>
        </fontFamily>
    </fontFamilies>

Jaspersoft@Studio 设置相关报表字体：

造成控制台输出相关提示信息：

WARN  net.sf.jasperreports.engine.export.PdfGlyphRenderer - Unpatched iText found, cannot use glyph rendering

原因如下：

![20200730101125710.png][]

在[https://mvnrepository.com/][https_mvnrepository.com] 中没有找到itext2.1.17.js7 版本下载，使用[https://search.maven.org/][https_search.maven.org] 检索到itext2.1.17 版本作为依赖下载本地，执行代码时出现上述错误信息。最后在jasperreport 开源的maven 仓库找到itext2.1.17.js4: [http://jasperreports.sourceforge.net/maven2/com/lowagie/itext/2.1.7.js4/][http_jasperreports.sourceforge.net_maven2_com_lowagie_itext_2.1.7.js4]

核心功能代码：

@RequestMapping("/one")
    	public void getReportByParam(HttpServletResponse response) {
    		ServletOutputStream sosRef = null;
    		// bean 连接获取
    		try {
    			Map<String, Object> map = new HashMap<String, Object>();				
    				map.put("quarter", "第一季度");
    				map.put("personUseCount", "111");
    				map.put("archCount", "99");
    				map.put("personCount", "74");
    				map.put("textNumbs", "59/38");
    				map.put("copyDrawingCount", "99");
     
    			// 获取文件流
    			ClassPathResource resource = new ClassPathResource("jasper" + File.separator + "Blank_A4_1.jasper");
    			InputStream jasperStream = resource.getInputStream();
     
    			sosRef = response.getOutputStream();
    			// 重点代码
    			JasperRunManager.runReportToPdfStream(jasperStream, sosRef, map, new JREmptyDataSource());
    			JasperRunManager.runReportToPdfStream(jasperStream, sosRef, map);
    			response.setContentType("application/pdf");
    		} catch (Exception e) {
    			e.printStackTrace();
    		} finally {
    			try {
    				sosRef.flush();
    				sosRef.close();
    			} catch (IOException e) {
    				// TODO Auto-generated catch block
    				e.printStackTrace();
    			}
    		}
    	}

依赖itext2.1.17.js 代码下载：
