java中word快速转pdf

网上其他方法转pdf要不转的太慢,要不就是损失格式,故而留下此方法留作备用。



一、依赖

<dependency>
    <groupId>com.aspose</groupId>
    <artifactId>aspose-words</artifactId>
    <version>21.6</version>
    <classifier>jdk16</classifier>
</dependency>

二、依赖包

请将aspose.7z文件解压,将解压后文件放到maven的com目录下。

三、代码

    public static InputStream wordConvertPdf(InputStream inputStream) {
        Document doc = null;
        ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
        try {
            // 加载输入流中的Word文档
            removeWaterMark(); // 移除水印(如果需要)
            doc = new Document(inputStream);
            // 将Word文档保存为PDF格式到ByteArrayOutputStream
            doc.save(outputStream, SaveFormat.PDF);
            // 返回生成的PDF文档流
            return new ByteArrayInputStream(outputStream.toByteArray());
        } catch (Exception e) {
            throw new RuntimeException("Failed to convert Word to PDF", e);
        } finally {

            }
        }
    }
