Java使用documents4j将word和excel转pdf

1. pom.xml添加documents4j依赖

<!-- documents4j -->
<dependency><groupId>com.documents4j</groupId><artifactId>documents4j-local</artifactId><version>1.0.3</version>
</dependency>
<!-- documents4j 转 word -->
<dependency><groupId>com.documents4j</groupId><artifactId>documents4j-transformer-msoffice-word</artifactId><version>1.0.3</version>
</dependency>
<!-- documents4j 转 pdf -->
<dependency><groupId>com.documents4j</groupId><artifactId>documents4j-transformer-msoffice-excel</artifactId><version>1.0.3</version>
</dependency>

2. 使用

/*** word/excel转pdf* @param inputWordPath 传入转换之前的路径 比如："D:\\printFile\\test.pdf"* @param outPdfPath 传入转换之后的路径 比如："D:\\printFile\\test.pdf"*/
private void wordOrExcelTransition(String inputWordPath, String outPdfPath){File inputWord = new File(inputWordPath);File outputFile = new File(outPdfPath);try  {InputStream docxInputStream = new FileInputStream(inputWord);OutputStream outputStream = new FileOutputStream(outputFile);IConverter converter = LocalConverter.builder().build();String fileTyle = inputWordPath.substring(inputWordPath.lastIndexOf("."), inputWordPath.length());//获取文件类型if(".docx".equals(fileTyle)){converter.convert(docxInputStream).as(DocumentType.DOCX).to(outputStream).as(DocumentType.PDF).execute();}else if(".doc".equals(fileTyle)){converter.convert(docxInputStream).as(DocumentType.DOC).to(outputStream).as(DocumentType.PDF).execute();}else if(".xls".equals(fileTyle)){converter.convert(docxInputStream).as(DocumentType.XLS).to(outputStream).as(DocumentType.PDF).execute();}else if(".xlsx".equals(fileTyle)){converter.convert(docxInputStream).as(DocumentType.XLSX).to(outputStream).as(DocumentType.PDF).execute();}outputStream.close();System.out.println("success");} catch (Exception e) {e.printStackTrace();}}
