Java使用documents4j将word和excel转pdf

1. pom.xml添加documents4j依赖

<dependency>
    <groupId>com.documents4jgroupId>
    <artifactId>documents4j-localartifactId>
    <version>1.0.3version>
dependency>

<dependency>
    <groupId>com.documents4jgroupId>
    <artifactId>documents4j-transformer-msoffice-wordartifactId>
    <version>1.0.3version>
dependency>

<dependency>
    <groupId>com.documents4jgroupId>
    <artifactId>documents4j-transformer-msoffice-excelartifactId>
    <version>1.0.3version>

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();
	  }
	}
