我试图通过飞碟和thymeleaf生成包含中文UTF-8个字符的pdf。但是生成的pdf忽略了所有的中文字符（拉丁文很好）。这是Thymeleaf配置
@Configuration
public class ThymeleafConfig {
@Bean
public ClassLoaderTemplateResolver fileTemplateResolver(){
ClassLoaderTemplateResolver fileTemplateResolver = new ClassLoaderTemplateResolver();
fileTemplateResolver.setPrefix("templates/");
fileTemplateResolver.setTemplateMode("HTML");
fileTemplateResolver.setSuffix(".html");
fileTemplateResolver.setCharacterEncoding("UTF-8");
fileTemplateResolver.setOrder(1);
return fileTemplateResolver;
}
@Bean
public SpringTemplateEngine templateEngine(){
SpringTemplateEngine springTemplateEngine = new SpringTemplateEngine();
springTemplateEngine.setEnableSpringELCompiler(true);
springTemplateEngine.setTemplateResolver(fileTemplateResolver());
return springTemplateEngine;
}
@Bean
public ThymeleafViewResolver thymeleafViewResolver() {
ThymeleafViewResolver resolver = new ThymeleafViewResolver();
resolver.setTemplateEngine(templateEngine());
resolver.setCharacterEncoding("UTF-8");
return resolver;
}
}
如您所见，我已将模板解析器和视图解析器的字符编码设置为UTF-8。
PDFUtil用于生成pdf
public class PDFUtil {
@Autowired
private TemplateEngine templateEngine;
public String createPdf(String templatename, String fileName, String modelName, Object model) throws IOException, DocumentException {
String fileNameUrl = "";
Context ctx = new Context();
ctx.setVariable(modelName, model);
String processedHtml = templateEngine.process(templatename, ctx);
FileOutputStream outputStream = null;
try {
final File outputFile = File.createTempFile(fileName, ".pdf");
outputStream = new FileOutputStream(outputFile);
ITextRenderer renderer = new ITextRenderer();
ITextFontResolver resolver = renderer.getFontResolver();
final ClassPathResource fonts = new ClassPathResource("fonts/PingFangSCRegular.ttf");
String test = fonts.getFilename();
resolver.addFont(fonts.getPath(), BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
renderer.setDocumentFromString(processedHtml);
renderer.layout();
renderer.createPDF(outputStream, false);
renderer.finishPDF();
FileSystemResource resource = new FileSystemResource(outputFile);
fileNameUrl = resource.getURL().toString();
}
finally {
if (outputStream != null) {
try {
outputStream.close();
} catch (IOException e) { }
}
}
return fileNameUrl;
}
}
在这里，我已经将中文字体添加到解析器中。
这是模板html头
<head th:fragment="html_head">
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>Title</title>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script src="https://cdn.jsdelivr.net/npm/bootstrap@5.1.3/dist/js/bootstrap.bundle.min.js"></script>
<script src="https://unpkg.com/jsbarcode@latest/dist/JsBarcode.all.min.js"></script>

<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/6.1.1/css/fontawesome.min.css" />
<style type="text/css">
@font-face {
font-family: 'PingFang SC Regular';
src: url('/fonts/PingFangSCRegular.ttf');
-fs-pdf-font-embed: embed;
-fs-pdf-font-encoding: Identity-H;
}
</style>
</head>
所以我试着声明字符集是UTF-8，字体系列是平方SC常规。但是毫不奇怪，这不起作用。
这是我添加到springboot项目中的maven依赖项

我要渲染的html主体
<body>
<div th:fragment="header(model)">
<div class="row">
<div class="col-4">
<img id="barcode" alt="111"/>
</div>
<div class="col-4">
<h3>啊啊啊啊啊啊aaa[[${model.title}]]</h3>
<p id="print-time">[[${model.printTime}]]</p>
</div>
</div>
</div>
</body>
有人能弄清楚为什么UTF-8字符没有显示在生成的pdf中吗？任何想法都将不胜感激。
在您的模板中，您声明了font-face，但没有将其应用于页面的内容。
您只需声明应使用字体：
body {font-family: 'PingFang SC Regular';}
此外，您不需要在模板中使用@font-face，因为您已将字体添加到渲染器（使用解析器. addFont）。
以下超文本标记语言应该可以正常工作：
<html>
<head>
<style>
body {font-family: 'PingFang SC Regular';}
</style>
</head>
<body>
<h3>啊啊啊啊啊啊</h3>
</body>
</html>
