[[${user.getName()}]]
[[${user.name}]]111
<p>Email: <span th:text="${user.email}"></span></p>

</html>

依赖

        <!-- thymeleaf for html to pdf --><dependency><groupId>org.thymeleaf</groupId><artifactId>thymeleaf</artifactId><version>${org.thymeleaf.version}</version><scope>compile</scope></dependency>

PDFGenerator

import org.springframework.stereotype.Component;

import org.thymeleaf.templateresolver.ClassLoaderTemplateResolver;
import org.xhtmlrenderer.pdf.ITextRenderer;import java.io.FileOutputStream;
import java.io.OutputStream;@Component
public class PdfGenerator {public PdfGenerator() {}public void generatePdfFromTemplate(User user, String templatePath, String outputPath) {try (OutputStream outputStream = new FileOutputStream(outputPath)) {Context context = new Context();context.setVariable("user", user);TemplateEngine templateEngine = new TemplateEngine();// 创建并配置模板解析器ClassLoaderTemplateResolver templateResolver = new ClassLoaderTemplateResolver();templateResolver.setPrefix("templates/");templateResolver.setSuffix(".html");templateResolver.setTemplateMode("HTML");// 将模板解析器设置到TemplateEngine中templateEngine.setTemplateResolver(templateResolver);String htmlContent = templateEngine.process(templatePath, context);ITextRenderer renderer = new ITextRenderer();renderer.setDocumentFromString(htmlContent);renderer.layout();renderer.createPDF(outputStream);} catch (Exception e) {e.printStackTrace();}}
}

使用

        String templatePath = "template.html";String outputPath = "C:\\Temp\\aaa\\2024\\3\\12\\output.pdf";PdfGenerator pdfGenerator = new PdfGenerator();pdfGenerator.generatePdfFromTemplate(User.builder().name("ss").email("22").build(), templatePath, outputPath);

导出成功
