可以使用Apache POI和iText库来实现将doc或docx文件转换成pdf。具体步骤如下:
1. 引入相关依赖
在pom.xml文件中添加以下依赖:
```xml
org.apache.poi
poi
4.1.2
org.apache.poi
poi-ooxml
4.1.2
com.itextpdf
itextpdf
5.5.13.2
```
2. 编写转换代码
```java
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import org.apache.poi.xwpf.usermodel.XWPFDocument;
import org.apache.poi.xwpf.converter.pdf.PdfConverter;
import org.apache.poi.xwpf.converter.pdf.PdfOptions;
import com.itextpdf.text.Document;
import com.itextpdf.text.PageSize;
import com.itextpdf.text.pdf.PdfWriter;
public class DocToPdfConverter {
public static void main(String[] args) throws IOException {
String docFilePath = "path/to/doc/file";
String pdfFilePath = "path/to/pdf/file";
// 读取doc文件
FileInputStream inputStream = new FileInputStream(new File(docFilePath));
XWPFDocument document = new XWPFDocument(inputStream);
// 设置pdf选项
PdfOptions options = PdfOptions.create();
options.fontEncoding("UTF-8");
// 转换成pdf文件
FileOutputStream outputStream = new FileOutputStream(new File(pdfFilePath));
PdfConverter.getInstance().convert(document, outputStream, options);
// 关闭流
inputStream.close();
outputStream.close();
// 如果需要将docx文件转换成pdf,可以使用以下代码
// FileInputStream inputStream = new FileInputStream(new File(docxFilePath));
// XWPFDocument document = new XWPFDocument(inputStream);
// PdfOptions options = PdfOptions.create();
// options.fontEncoding("UTF-8");
// PdfWriter writer = Pdf
