1. 配置


@Configuration

public class PdfConfig {
    @ConfigurationProperties(prefix = "little.pdf")
    @Bean
    public Itext5PdfRenderConfig  littlePdfConfig(){
        Itext5PdfRenderConfig renderConfig = new Itext5PdfRenderConfig();
        return renderConfig;
    }
    @Bean
    @ConditionalOnBean(value = {Itext5PdfRenderConfig.class})
    public LittlePdfTemplateRender littlePdfTemplateRender() {
        ClassLoaderTemplateResolver resolver = new ClassLoaderTemplateResolver();
        resolver.setOrder(1);
        resolver.setCacheable(true);
        resolver.setSuffix(".html");
        resolver.setCharacterEncoding("UTF-8");
        resolver.setTemplateMode(TemplateMode.HTML5);
        resolver.setPrefix("pdftemplate/");
        TemplateEngine templateEngine = new TemplateEngine();
        templateEngine.addTemplateResolver(resolver);
        WordTemplateRender wordTemplateRender = new WordTemplateRender("d://temp/");
        wordTemplateRender.setSuffix("docx");
        ThymeleafHtmlRender thymeleafHtmlRender = new ThymeleafHtmlRender(templateEngine);
        thymeleafHtmlRender.setSuffix("html");
        Itext5PdfRenderConfig renderConfig = littlePdfConfig();
        TemplateRender thymeleafRender = new TemplateRender(renderConfig);
        thymeleafRender.addRender(thymeleafHtmlRender);
        thymeleafRender.addRender(wordTemplateRender);
        return thymeleafRender;
    }
}

little.pdf.fontsDir=G:\github\little-pdf\little-pdf-springboot-sample\src\main\resources\fonts
little.pdf.resourcesDir=classpath:/pdftemplate
little.pdf.charset=UTF-8

2. 模板渲染

  littlePdfTemplateRender.render(template,jsonObject,outputStreamm);
