1 配置pom文件
我用的是5.4.3的版本
<dependency><groupId>com.itextpdf</groupId><artifactId>itextpdf</artifactId><version>5.4.3</version></dependency>
2 按页(逐页、单页)拆分PDF代码
/*** @author Reverse_XML* 把PDF 按页(逐页、单页)拆分(一页一页拆分，一页为一个新PDF文件)* @param path 源PDF路径* @param fileName 源PDF文件名* @param outputPath 拆分后输出的PDF路径*/public static void splitPDFOneByOne(String path, String fileName, String outputPath) {String sep = java.io.File.separator;PdfReader reader = null;int numberOfPages = 0;try {reader = new PdfReader(path + sep + fileName);numberOfPages = reader.getNumberOfPages();for (int i = 1; i <= numberOfPages; i++) {Document document = null;PdfCopy copy = null;try {document = new Document(reader.getPageSize(1));String savePath = outPath + sep +fileName.substring(0, fileName.lastIndexOf(".")) + "_" + i + ".pdf";copy = new PdfCopy(document, new FileOutputStream(savePath));document.open();document.newPage();PdfImportedPage page = copy.getImportedPage(reader, i);copy.addPage(page);} finally {if (document != null)document.close();if (copy != null)copy.close();}}} catch (IOException e) {log.error(e.getMessage(), e);} catch (DocumentException e) {log.error(e.getMessage(), e);} finally {if (reader != null)reader.close();}}
3 调用示例
将指定的PDF逐页拆分(一页一页拆分，一页为一个新的PDF)
public static void main(String[] args) {try {PDFUtils.splitPDFOneByOne("D:\\inputPath", "test.pdf", "D:\\outputPath");} catch (Exception e) {log.error(e.getMessage(), e);}}
