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" +

"</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:UserslaoyoujiDesktopMark.doc";//所需要转为PDF的Word文档
InputStream stream = new FileInputStream(fromPath);
Document convertDoc = new Document(stream);
String toPath = "C:UserslaoyoujiDesktopMark.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.RIGHT
footerpara.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*/
}
效果图
Excel转为PDF
