html或者jsp转pdf文档

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

       <!-- html转pdf-->
        <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
在

 <component name="PropertiesComponent">

代码下面添加

 <property name="dynamic.classpath" value="true" />
