2、将word转换为pdf文件

2.1、在pom.xml文件中添加依赖包
<dependency>
<groupId>com.lowagie</groupId>
<artifactId>itext</artifactId>
<version>2.1.7</version>
<type>jar</type>
</dependency>
<dependency>
<groupId>fr.opensagres.xdocreport</groupId>
<artifactId>org.apache.poi.xwpf.converter.pdf</artifactId>
<version>1.0.4</version>
</dependency>
2.2、
```
public static void convertPdf(String docxFilePath,String pdfFilePath) throws Exception{
File docxFile=new File(docxFilePath);
File pdfFile=new File(pdfFilePath);
//转换pdf文件
if(docxFile.exists()){
if(!pdfFile.exists()){
InputStream inStream=new FileInputStream(docxFilePath);
XWPFDocument document = new XWPFDocument(inStream);
//HWPFDocument document = new HWPFDocument(inStream);
OutputStream out = new FileOutputStream(pdfFilePath);
PdfOptions options = PdfOptions.create();
//ExtITextFontRegistry fontProvider=ExtITextFontRegistry.getRegistry();
//options.fontProvider(fontProvider);
PdfConverter.getInstance().convert(document, out, options);
}else{
System.out.println("PDF文件已存在，无需再次转换");
}
}else{
}
}
```
2.3、主方法调用
```
String filepath = "C:/01_workplace/02_upload_workplace/LOI_01.docx";
String outpath = "C:/01_workplace/02_upload_workplace/LOI_01.pdf";
convertPdf(filepath,outpath);
```
