一、代码

package com.citydo.checkandbigdataquery.mq;
    
    import com.itextpdf.text.Document;
    import com.itextpdf.text.DocumentException;
    import com.itextpdf.text.Paragraph;
    import com.itextpdf.text.pdf.BaseFont;
    import com.itextpdf.text.pdf.PdfWriter;
    import lombok.extern.slf4j.Slf4j;
    import org.xhtmlrenderer.pdf.ITextFontResolver;
    import org.xhtmlrenderer.pdf.ITextRenderer;
    
    import java.io.File;
    import java.io.FileNotFoundException;
    import java.io.FileOutputStream;
    import java.io.OutputStream;
    
    
    @Slf4j
    public class htmlToPdf { 
    
    
        /** * 将HTML转成PD格式的文件。html文件的格式比较严格 * @param htmlFile * @param pdfFile * @throws Exception */
        public static void html2pdf(String htmlFile, String pdfFile) throws Exception { 
            // step 1
            String url = new File(htmlFile).toURI().toURL().toString();
            // step 2
            OutputStream os = new FileOutputStream(pdfFile);
            ITextRenderer renderer = new ITextRenderer();
            renderer.setDocument(url);
            // step 3 解决中文支持
            ITextFontResolver fontResolver = renderer.getFontResolver();
            if("linux".equals(getCurrentOperatingSystem())){ 
                fontResolver.addFont("/usr/share/fonts/chiness/simsun.ttc", BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
            }else{ 
                fontResolver.addFont("c:/Windows/Fonts/simsun.ttc", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);
            }
            renderer.getSharedContext().setBaseURL("file:/E:/test/m/");//本地文件
            //renderer.getSharedContext().setBaseURL("http://www.jiajiajia.club:8089/img/photo/");//网络文件
            renderer.layout();
            renderer.createPDF(os);
            os.close();
            System.out.println("create pdf done!!");
    
        }
    
        public static String getCurrentOperatingSystem(){ 
            String os = System.getProperty("os.name").toLowerCase();
            return os;
        }
    
    // public static void main(String[] args) { 
    // String htmlFile = "E:\\test\\m\\a.html";
    // String pdfFile = "E:\\test\\m\\a.pdf";
    // String htmlFile = "c:/sign.jsp";
    // String pdfFile = "c:/sign.pdf";
    // try { 
    // htmlToPdf.html2pdf(htmlFile, pdfFile);
    // } catch (FileNotFoundException e) { 
    // e.printStackTrace();
    // } catch (Exception e) { 
    // e.printStackTrace();
    // }
    // }
    
        /** * @param args */
        public static void main(String[] args) { 
            Document document = new Document();
            try { 
                PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream("D:\\lean\\test.pdf"));
                document.open();
                document.add(new Paragraph("A Hello World PDF document."));
                document.close();
                writer.close();
            } catch (DocumentException e) { 
                e.printStackTrace();
            } catch (FileNotFoundException e) { 
                e.printStackTrace();
            }
        }
    }

二、相关依赖

<dependency>
                <groupId>com.itextpdf</groupId>
                <artifactId>itextpdf</artifactId>
                <version>5.5.9</version>
            </dependency>
    
            <dependency>
                <groupId>com.itextpdf.tool</groupId>
                <artifactId>xmlworker</artifactId>
                <version>5.5.9</version>
            </dependency>
    
            <dependency>
                <groupId>com.itextpdf</groupId>
                <artifactId>itext-asian</artifactId>
                <version>5.2.0</version>
            </dependency>
    
            <dependency>
                <groupId>org.xhtmlrenderer</groupId>
                <artifactId>flying-saucer-pdf-itext5</artifactId>
                <version>9.1.20</version>
            </dependency>

三、解决 `Command line is too long. Shorten command line for htmlToPdf or also for Application default configu` 报错
