请建议

使用的罐子：

您缺少一些库

我可以通过添加以下库来运行您的代码：

Apache POI 3.15 org.apache.poi.xwpf.converter.core-1.0.6.jar org.apache.poi.xwpf.converter.pdf-1.0.6.jar fr.opensagres.xdocreport.itext.extension-2.0.0.jar itext-2.1.7.jar ooxml-schemas-1.3.jar ApachePOI3.15 org.apache.poi.xwpf.converter.core-1.0.6.jar org.apache.poi.xwpf.converter.pdf-1.0.6.jar fr.opensagres.xdocreport.itext.extension-2.0.0.jar itext-2.1.7.jar ooxml-schemas-1.3.jar

我已经成功地转换了一个6页长的Word文档（.docx），其中包含表格、图像和各种格式。

除了VivekRatanSinha之外，我还想为将来需要它的人发布完整的代码和所需的JAR

代码：

import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

import org.apache.poi.xwpf.converter.pdf.PdfConverter;
import org.apache.poi.xwpf.converter.pdf.PdfOptions;
import org.apache.poi.xwpf.usermodel.XWPFDocument;

public class WordConvertPDF {
    public static void main(String[] args) {
        WordConvertPDF cwoWord = new WordConvertPDF();
        cwoWord.ConvertToPDF("D:/Test.docx", "D:/Test.pdf");
    }

    public void ConvertToPDF(String docPath, String pdfPath) {
        try {
            InputStream doc = new FileInputStream(new File(docPath));
            XWPFDocument document = new XWPFDocument(doc);
            PdfOptions options = PdfOptions.create();
            OutputStream out = new FileOutputStream(new File(pdfPath));
            PdfConverter.getInstance().convert(document, out, options);
        } catch (IOException ex) {
            System.out.println(ex.getMessage());
        }
    }
}

和罐子：

import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

import org.apache.poi.xwpf.converter.pdf.PdfConverter;

public class WordConvertPDF {
    public static void main(String[] args) {
        WordConvertPDF cwoWord = new WordConvertPDF();
        cwoWord.ConvertToPDF("D:/Test.docx", "D:/Test.pdf");
    }

    public void ConvertToPDF(String docPath, String pdfPath) {
        try {
            InputStream doc = new FileInputStream(new File(docPath));
            XWPFDocument document = new XWPFDocument(doc);
            PdfOptions options = PdfOptions.create();
            OutputStream out = new FileOutputStream(new File(pdfPath));
            PdfConverter.getInstance().convert(document, out, options);
        } catch (IOException ex) {
            System.out.println(ex.getMessage());
        }
    }
}

享受：）

我使用这个代码

private byte[] toPdf(ByteArrayOutputStream docx) {
    InputStream isFromFirstData = new ByteArrayInputStream(docx.toByteArray());

    XWPFDocument document = new XWPFDocument(isFromFirstData);
    PdfOptions options = PdfOptions.create();

    //make new file in c:\temp\
    OutputStream out = new FileOutputStream(new File("c:\\tmp\\HelloWord.pdf"));
    PdfConverter.getInstance().convert(document, out, options);

    //return byte array for return in http request.
    ByteArrayOutputStream pdf = new ByteArrayOutputStream();
    PdfConverter.getInstance().convert(document, pdf, options);

    document.write(pdf);
    document.close();
    return pdf.toByteArray();
}

我做了大量研究，发现Documents4j是将docx转换为pdf的最佳免费API对齐，字体所有文档4J都做得很好

Maven依赖项：

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

只需手动添加一个依赖项（其他依赖项应自动拉入）。到目前为止，最新版本是2.0.2

格拉德尔：

依赖项{
//你应该已经拥有的
实现“org.apache.poi:poi ooxml:latest.release”
//将以下行添加到build.gradle中的DEPENDENCIES块
实现“fr.opensagres.xdocreport:fr.opensagres.poi.xwpf.converter.pdf:2.0.2”
}

仅限Maven：

<dependency>
    <groupId>fr.opensagres.xdocreport</groupId>
    <artifactId>fr.opensagres.poi.xwpf.converter.pdf</artifactId>
    <version>2.0.2</version>
</dependency>


fr.opensagres.xdocreport
fr.opensagres.poi.xwpf.converter.pdf
2.0.2

我将提供3种将docx转换为pdf的方法：

使用itext、opensagres和apache poi

代码：

依赖项：使用Maven解析依赖项

fr.opensagres.poi.xwpf.converter.core的新版本2.0.2使用apache poi 4.0.1和itext 2.17运行。您只需要在Maven中添加以下依赖项，然后Maven将自动下载所有依赖项。（更新了Maven项目，因此它下载了所有这些库及其所有依赖项）

如果您的文档非常丰富，并且选择在Linux/Unix上进行转换，那么实现起来可能会“有点”痛苦

我建议的解决方案是：使用Docker支持的无状态API将HTML、Markdown和Office文档转换为PDF

启动容器

$docker run--rm-p 3000:3000编码机/gotenberg:6

向容器发出请求。下面是如何使用
```
curl
```
：

$curl——请求发布\
--网址http://localhost:3000/convert/office \
--标题“内容类型：多部分/表单数据”\
--表单文件=@document.docx\
--表单文件=@document2.docx\
-o result.pdf

将其部署到您的基础架构（例如，作为单独的微服务），并通过Java服务发出简单的HTTP请求。在响应中获取您的PDF文件，并对其执行所需操作

经过测试，效果很好

Docx4j是开源的，是将Docx转换为pdf的最佳API，没有任何对齐或字体问题
