aspose使用合集java（Word、Excel、PPT转PDF

Aspose.word for Java是一个类库，它使应用程序能够执行大量的文档处理任务。Aspose.word支持DOC、DOCX、RTF、HTML、OpenDocument、PDF、XPS、EPUB等格式。Aspose不使用Microsoft Word就可以生成、修改、转换、渲染和打印文档

文档所需jar包

获取license

private static boolean getLicense() {boolean result = false;try {// 凭证String license ="<License>\n" +"  <Data>\n" +"    <Products>\n" +"      <Product>Aspose.Total for Java</Product>\n" +"      <Product>Aspose.Words for Java</Product>\n" +"    </Products>\n" +"    <EditionType>Enterprise</EditionType>\n" +"    <SubscriptionExpiry>20991231</SubscriptionExpiry>\n" +"    <LicenseExpiry>20991231</LicenseExpiry>\n" +"    <SerialNumber>8bfe198c-7f0c-4ef8-8ff0-acc3237bf0d7</SerialNumber>\n" +"  </Data>\n" +"  <Signature>sNLLKGMUdF0r8O1kKilWAGdgfs2BvJb/2Xp8p5iuDVfZXmhppo+d0Ran1P9TKdjV4ABwAgKXxJ3jcQTqE/2IRfqwnPf8itN8aFZlV3TJPYeD3yWE7IT55Gz6EijUpC7aKeoohTb4w2fpox58wWoF3SNp6sK6jDfiAUGEHYJ9pjU=</Signature>\n" +"</License>";InputStream is = new ByteArrayInputStream(license.getBytes("UTF-8"));License asposeLic = new License();asposeLic.setLicense(is);result = true;} catch (Exception e) {e.printStackTrace();}return result;}

简单的Word转为PDF

 public static void main(String[] args) {//获取文档流String fromPath = "";//所需要转为PDF的Word文档InputStream stream = new FileInputStream(fromPath);Document convertDoc = new Document(stream);String toPath = "";//转为PDF的路径convertDoc.save(toPath , SaveFormat.PDF);//saveFormat此处的saveFormat在一下有解释}

saveFormat ：根据所需选择转换格式

public final class SaveFormat {public static final int UNKNOWN = 0;public static final int DOC = 10;public static final int DOT = 11;public static final int DOCX = 20;public static final int DOCM = 21;public static final int DOTX = 22;public static final int DOTM = 23;public static final int FLAT_OPC = 24;public static final int FLAT_OPC_MACRO_ENABLED = 25;public static final int FLAT_OPC_TEMPLATE = 26;public static final int FLAT_OPC_TEMPLATE_MACRO_ENABLED = 27;public static final int RTF = 30;public static final int WORD_ML = 31;public static final int PDF = 40;public static final int XPS = 41;public static final int XAML_FIXED = 42;public static final int SVG = 44;public static final int HTML_FIXED = 45;public static final int OPEN_XPS = 46;public static final int PS = 47;public static final int PCL = 48;public static final int HTML = 50;public static final int MHTML = 51;public static final int EPUB = 52;public static final int ODT = 60;public static final int OTT = 61;public static final int TEXT = 70;public static final int XAML_FLOW = 71;public static final int XAML_FLOW_PACK = 72;public static final int TIFF = 100;public static final int PNG = 101;public static final int BMP = 102;public static final int EMF = 103;public static final int JPEG = 104;public static final int GIF = 105;public static final int length = 35;
}

Word转为PDF的同时往Word上填充数据

填充数据有两种填充方式

书签填充

2.MergeFile域填充

以下以书签为例

public static void main(String[] args) {if (!getLicense()) {return;}//获取文档流String fromPath = "C:\Users\laoyouji\Desktop\Mark.doc";//所需要转为PDF的Word文档InputStream stream = new FileInputStream(fromPath);Document convertDoc = new Document(stream);String toPath = "C:\Users\laoyouji\Desktop\Mark.pdf";//转为PDF的路径        //get("mark")此处的mark为加入Word的书签//setText("填充的数据")是你需要的赋值convertDoc.getRange().getBookmarks().get("mark").setText("填充的数据");convertDoc.save(toPath , SaveFormat.PDF);}

生成后的PDF文档填充了刚刚的文本字段

往Word中填充图片

public static void main(String[] args) throws Exception {if (!getLicense()) {return;}//获取文档流String fromPath = "C:/Users/17734/Desktop/Mark.doc";//所需要转为PDF的Word文档InputStream stream = new FileInputStream(fromPath);Document convertDoc = new Document(stream);String toPath = "C:/Users/17734/Desktop/Mark.pdf";//转为PDF的路径//get("mark")此处的mark为加入Word的书签//setText("填充的数据")是你需要的赋值try {DocumentBuilder builder = new DocumentBuilder(convertDoc);String picturePath = "C:\\Users\\17734\\Desktop\\阿泽.jpg";//所需插入图片的路径double width = 100;//插入图片的宽度double height = 100;//插入图片的高度Shape shape = builder.insertImage(picturePath, width, height);shape.setWrapType(WrapType.NONE);shape.setLeft(100);//此处的100是离文档左边的距离shape.setTop(100);//此处的100是离文档顶部的距离} catch (Exception e) {System.out.println("------图片不存在------");}convertDoc.save(toPath , SaveFormat.PDF);}

效果图

往Word中加入页码

public static void main(String[] args) throws Exception {if (!getLicense()) {return;}//获取文档流String fromPath = "C:/Users/17734/Desktop/Mark.doc";//所需要转为PDF的Word文档InputStream stream = new FileInputStream(fromPath);Document convertDoc = new Document(stream);String toPath = "C:/Users/17734/Desktop/Mark.pdf";//转为PDF的路径pagination(convertDoc,ParagraphAlignment.RIGHT);convertDoc.save(toPath , SaveFormat.PDF);}

 //添加页码private static void pagination(Document convertDoc, Integer position) throws Exception {/*添加页码*/HeaderFooter footer = new HeaderFooter(convertDoc, HeaderFooterType.FOOTER_PRIMARY);convertDoc.getFirstSection().getHeadersFooters().add(footer);//页脚段落Paragraph footerpara = new Paragraph(convertDoc);//ParagraphAlignment.RIGHTfooterpara.getParagraphFormat().setAlignment(position);Run footerparaRun = new Run(convertDoc, "共 ");footerparaRun.getFont().setName("方正仿宋简体");footerparaRun.getFont().setSize(12.0);footerpara.appendChild(footerparaRun);footerpara.appendField(FieldType.FIELD_NUM_PAGES, false);//总页码footerparaRun = new Run(convertDoc, " 页，第 ");footerparaRun.getFont().setName("方正仿宋简体");footerparaRun.getFont().setSize(12.0);footerpara.appendChild(footerparaRun);footerpara.appendField(FieldType.FIELD_PAGE, false);//当前页码footerparaRun = new Run(convertDoc, " 页");footerparaRun.getFont().setName("方正仿宋简体");footerparaRun.getFont().setSize(12.0);footerpara.appendChild(footerparaRun);footer.appendChild(footerpara);/*添加页码*/}

总结：
aspose 自己项目中使用到的一些功能，如果有错误，望指正！！！
生活很难，请你开心一点~
