java将Word转换成PDF三种方法
原文链接:https://blog.csdn.net/weixin_38409915/article/details/125317664
网上有很多将Word转换成PDF的方式,这里找了三种比较简单的工具:poi、jacob和aspose。
1.POI
依赖
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi-ooxml</artifactId>
<version>3.17</version>
</dependency>
<dependency>
<groupId>fr.opensagres.xdocreport</groupId>
<artifactId>fr.opensagres.poi.xwpf.converter.pdf-gae</artifactId>
<version>2.0.1</version>

工具类
FileInputStream fileInputStream = new FileInputStream("F:\\poi笔记.docx");
XWPFDocument xwpfDocument = new XWPFDocument(fileInputStream);
PdfOptions pdfOptions = PdfOptions.create();
FileOutputStream fileOutputStream = new FileOutputStream("F:\\poi笔记.pdf");
PdfConverter.getInstance().convert(xwpfDocument,fileOutputStream,pdfOptions);
fileInputStream.close();
fileOutputStream.close();

2.jacob
jacob 缺点:需要 window 环境,而且速度是最慢的需要安装 msofficeWord 以及 SaveAsPDFandXPS.exe ( word 的一个插件,用来把 word 转化为 pdf )
开发流程:
SaveAsPDFandXPS 下载地址: http://www.microsoft.com/zh-cn/download/details.aspx?id=7
jacob 包下载地址: http://sourceforge.net/projects/jacob-project/
1、安装SaveAsPDFandXPS
2、下载 jacob 解压后存放路径:
jacob.jar 放在 C:\Program Files\Java\jdk1.8.0_171\jre\lib\ext目录下
jacob.dll 放在 C:\Program Files\Java\jdk1.8.0_171\jre\bin 目录下
工具类
public class Word2PdfJacobUtil {
/* 转PDF格式值 */
private static final int wdFormatPDF = 17;
/**
* Word文档转换
*
* @param inputFile
* @param pdfFile
*/
public static boolean word2PDF(String inputFile, String pdfFile) {
ComThread.InitMTA(true);
long start = System.currentTimeMillis();
ActiveXComponent app = null;
Dispatch doc = null;
try {
app = new ActiveXComponent("Word.Application");// 创建一个word对象
app.setProperty("Visible", new Variant(false)); // 不可见打开word
app.setProperty("AutomationSecurity", new Variant(3)); // 禁用宏
Dispatch docs = app.getProperty("Documents").toDispatch();// 获取文挡属性
System.out.println("打开文档 >>> " + inputFile);
// Object[]第三个参数是表示“是否只读方式打开”
// 调用Documents对象中Open方法打开文档,并返回打开的文档对象Document
doc = Dispatch.call(docs, "Open", inputFile, false, true).toDispatch();
System.out.println("转换文档 [" + inputFile + "] >>> [" + pdfFile + "]");
// 调用Document对象的SaveAs方法,将文档保存为pdf格式
// word保存为pdf格式宏,值为17
Dispatch.call(doc, "SaveAs", pdfFile, wdFormatPDF);// word保存为pdf格式宏,值为17
long end = System.currentTimeMillis();
System.out.println("用时:" + (end - start) + "ms.");
return true;
} catch (Exception e) {
e.printStackTrace();
System.out.println("========Error:文档转换失败:" + e.getMessage());
} finally {
Dispatch.call(doc, "Close", false);
System.out.println("关闭文档");
if (app != null)
app.invoke("Quit", new Variant[] {});
// 如果没有这句话,winword.exe进程将不会关闭
ComThread.Release();
ComThread.quitMainSTA();
}
return false;
}
}

public static void main(String[] arg){
String docPath = "C:\\Users\\Administrator\\Desktop\\test.docx";
String pdfPath = "C:\\Users\\Administrator\\Desktop\\test.pdf";
boolean res = Word2PdfJacobUtil.word2PDF(docPath, pdfPath);
System.out.println(res);
}

结果如下:
3.aspose
当文档中含有中文字符时,该段代码的执行需要调用操作系统的本地字体库支持,否则所有中文字符都将乱码。
该段代码如果想要在Linux服务器上完美运行,需要给Linux服务器安装中文字体库
如何在Linux环境安装Windows字体库,将在本人的另一篇文章里详细讲解
Java使用Spire.Pdf或Aspose-Words实现Word转换Pdf在Linux服务器上的中文乱码问题
建议将jar包下载下来并上传私服里去

使用aspose不需要像jacob那样往jdk里加入ddl文件,但是需要在项目里加入一个license.xml,不然生成的pdf会有水印
license.xml如下:

工具类:
public class Word2PdfAsposeUtil {
public static boolean getLicense() {
boolean result = false;
try {
InputStream is = Test.class.getClassLoader().getResourceAsStream("\\license.xml"); // license.xml应放在..\WebRoot\WEB-INF\classes路径下
License aposeLic = new License();
aposeLic.setLicense(is);
result = true;
} catch (Exception e) {
e.printStackTrace();
}
return result;
}
public static boolean doc2pdf(String inPath, String outPath) {
if (!getLicense()) { // 验证License 若不验证则转化出的pdf文档会有水印产生
return false;
}
FileOutputStream os = null;
try {
long old = System.currentTimeMillis();
File file = new File(outPath); // 新建一个空白pdf文档
os = new FileOutputStream(file);
Document doc = new Document(inPath); // Address是将要被转化的word文档
doc.save(os, SaveFormat.PDF);// 全面支持DOC, DOCX, OOXML, RTF HTML, OpenDocument, PDF,
// EPUB, XPS, SWF 相互转换
long now = System.currentTimeMillis();
System.out.println("pdf转换成功,共耗时:" + ((now - old) / 1000.0) + "秒"); // 转化用时
} catch (Exception e) {
e.printStackTrace();
return false;
}finally {
if (os != null) {
try {
os.flush();
os.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
return true;
}
