使用maven引入jar

<dependency>
        <groupId>com.itextpdf</groupId>
        <artifactId>itextpdf</artifactId>
        <version>5.2.0</version>
    </dependency>
    <dependency>
        <groupId>com.itextpdf</groupId>
        <artifactId>itext-asian</artifactId>
        <version>5.2.0</version>
    </dependency>

创建exportToPDF工具类

package com.os.core.util.file.exportPdf;
    
    import com.itextpdf.text.*;
    import com.itextpdf.text.pdf.BaseFont;
    import com.itextpdf.text.pdf.FontSelector;
    import com.itextpdf.text.pdf.PdfWriter;
    
    import java.io.FileNotFoundException;
    import java.io.FileOutputStream;
    
    /**
     * Created by PengSongHe on 2016/10/20 0020.
     */
    public class exportToPDF {
        public static void main(String[] args) {
            try {
    
                Document document = new Document();//默认A4
                PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream("d:/HelloWorld.pdf"));
                writer.setPdfVersion(PdfWriter.PDF_VERSION_1_7);
                document.addCreationDate();
                document.addCreator("飞翔家族");
                document.addTitle("export pdf");
                document.addKeywords("export");
                document.addSubject("飞翔家族 export pdf");
                document.open();
    
    //处理中文，需要itextasian.jar支持
    
                FontSelector selector = new FontSelector();
                selector.addFont(FontFactory.getFont(FontFactory.TIMES_ROMAN, 12));
                selector.addFont(FontFactory.getFont("STSongStd-Light", "UniGB-UCS2-H", BaseFont.NOT_EMBEDDED));
                Phrase phrase = selector.process("HelloWord！你好。\u4fdd\u5b58");
                document.add(new Paragraph(phrase));
                //添加新页
                //document.newPage();
                //writer.setPageEmpty(false);
                //document.add(new Paragraph("New page"));
                document.close();
            } catch (FileNotFoundException e) {
                e.printStackTrace();
            } catch (DocumentException e) {
                e.printStackTrace();
            }
        }
    
    }
