创建word

The following are the steps to create a simple Word document containing several paragraphs by using Spire.Doc for Java.

• Create a Document object.
• Add a section using Document.addSection() method.
• Set the page margins using Section.getPageSetup().setMargins() method.
• Add several paragraphs to the section using Section.addParagraph() method.
• Add text to the paragraphs using Paragraph.appendText() method.
• Create ParagraphStyle objects, and apply them to separate paragraphs using Paragraph.applyStyle() method.
• Save the document to a Word file using Document.saveToFile() method.

package com.et.spire.doc;import com.spire.doc.Document;
import com.spire.doc.FileFormat;
import com.spire.doc.Section;
import com.spire.doc.documents.HorizontalAlignment;
import com.spire.doc.documents.Paragraph;
import com.spire.doc.documents.ParagraphStyle;import java.awt.*;public class CreateWordDocument {public static void main(String[] args) {//Create a Document objectDocument doc = new Document();//Add a sectionSection section = doc.addSection();//Set the page marginssection.getPageSetup().getMargins().setAll(40f);//Add a paragraph as titleParagraph titleParagraph = section.addParagraph();titleParagraph.appendText("Introduction of Spire.Doc for Java");//Add two paragraphs as bodyParagraph bodyParagraph_1 = section.addParagraph();bodyParagraph_1.appendText("Spire.Doc for Java is a professional Word API that empowers Java applications to " +"create, convert, manipulate and print Word documents without dependency on Microsoft Word.");Paragraph bodyParagraph_2 = section.addParagraph();bodyParagraph_2.appendText("By using this multifunctional library, developers are able to process copious tasks " +"effortlessly, such as inserting image, hyperlink, digital signature, bookmark and watermark, setting " +"header and footer, creating table, setting background image, and adding footnote and endnote.");//Create and apply a style for title paragraphParagraphStyle style1 = new ParagraphStyle(doc);style1.setName("titleStyle");style1.getCharacterFormat().setBold(true);;style1.getCharacterFormat().setTextColor(Color.BLUE);style1.getCharacterFormat().setFontName("Times New Roman");style1.getCharacterFormat().setFontSize(12f);doc.getStyles().add(style1);titleParagraph.applyStyle("titleStyle");//Create and apply a style for body paragraphsParagraphStyle style2 = new ParagraphStyle(doc);style2.setName("paraStyle");style2.getCharacterFormat().setFontName("Times New Roman");style2.getCharacterFormat().setFontSize(12);doc.getStyles().add(style2);bodyParagraph_1.applyStyle("paraStyle");bodyParagraph_2.applyStyle("paraStyle");//Set the horizontal alignment of paragraphstitleParagraph.getFormat().setHorizontalAlignment(HorizontalAlignment.Center);bodyParagraph_1.getFormat().setHorizontalAlignment(HorizontalAlignment.Justify);bodyParagraph_2.getFormat().setHorizontalAlignment(HorizontalAlignment.Justify);//Set the first line indentbodyParagraph_1.getFormat().setFirstLineIndent(30) ;bodyParagraph_2.getFormat().setFirstLineIndent(30);//Set the after spacingtitleParagraph.getFormat().setAfterSpacing(10);bodyParagraph_1.getFormat().setAfterSpacing(10);//Save to filedoc.saveToFile("/Users/liuhaihua/tmp/WordDocument.docx", FileFormat.Docx_2013);doc.close();}
}

word添加新页

The steps to add a new page at the end of a Word document include locating the last section, and then inserting a page break at the end of that section's last paragraph. This way ensures that any content added subsequently will start displaying on a new page, maintaining the clarity and coherence of the document structure. The detailed steps are as follows:

• Create a Document object.
• Load a Word document using the Document.loadFromFile() method.
• Get the body of the last section of the document using Document.getLastSection().getBody().
• Add a page break by calling Paragraph.appendBreak(BreakType.Page_Break) method.
• Create a new paragraph style ParagraphStyle object.
• Add the new paragraph style to the document's style collection using Document.getStyles().add(paragraphStyle) method.
• Create a new paragraph Paragraph object and set the text content.
• Apply the previously created paragraph style to the new paragraph using Paragraph.applyStyle(paragraphStyle.getName()) method.
• Add the new paragraph to the document using Body.getChildObjects().add(paragraph) method.
• Save the resulting document using the Document.saveToFile() method.

package com.et.spire.doc;import com.spire.doc.*;
import com.spire.doc.documents.*;public class AddOnePage {public static void main(String[] args) {// Create a new document objectDocument document = new Document();// Load a sample document from a filedocument.loadFromFile("/Users/liuhaihua/tmp/WordDocument.docx");// Get the body of the last section of the documentBody body = document.getLastSection().getBody();// Insert a page break after the last paragraph in the bodybody.getLastParagraph().appendBreak(BreakType.Page_Break);// Create a new paragraph styleParagraphStyle paragraphStyle = new ParagraphStyle(document);paragraphStyle.setName("CustomParagraphStyle1");paragraphStyle.getParagraphFormat().setLineSpacing(12);paragraphStyle.getParagraphFormat().setAfterSpacing(8);paragraphStyle.getCharacterFormat().setFontName("Microsoft YaHei");paragraphStyle.getCharacterFormat().setFontSize(12);// Add the paragraph style to the document's style collectiondocument.getStyles().add(paragraphStyle);// Create a new paragraph and set the text contentParagraph paragraph = new Paragraph(document);paragraph.appendText("Thank you for using our Spire.Doc for Java product. The trial version will add a red watermark to the generated result document and only supports converting the first 10 pages to other formats. Upon purchasing and applying a license, these watermarks will be removed, and the functionality restrictions will be lifted.");// Apply the paragraph styleparagraph.applyStyle(paragraphStyle.getName());// Add the paragraph to the body's content collectionbody.getChildObjects().add(paragraph);// Create another new paragraph and set the text contentparagraph = new Paragraph(document);paragraph.appendText("To fully experience our product, we provide a one-month temporary license for each of our customers for free. Please send an email to [e-mail], and we will send the license to you within one working day.");// Apply the paragraph styleparagraph.applyStyle(paragraphStyle.getName());// Add the paragraph to the body's content collectionbody.getChildObjects().add(paragraph);// Save the document to a specified pathdocument.saveToFile("/Users/liuhaihua/tmp/Add a Page.docx", FileFormat.Docx);// Close the documentdocument.close();// Dispose of the document object's resourcesdocument.dispose();}
}

读取word内容

Using the FixedLayoutDocument class and FixedLayoutPage class makes it easy to extract content from a specified page. To facilitate viewing the extracted content, the following example code saves the extracted content to a new Word document. The detailed steps are as follows:

• Create a Document object.
• Load a Word document using the Document.loadFromFile() method.
• Create a FixedLayoutDocument object.
• Obtain a FixedLayoutPage object for a page in the document.
• Use the FixedLayoutPage.getSection() method to get the section where the page is located.
• Get the index position of the first paragraph on the page within the section.
• Get the index position of the last paragraph on the page within the section.
• Create another Document object.
• Add a new section using Document.addSection().
• Clone the properties of the original section to the new section using Section.cloneSectionPropertiesTo(newSection) method.
• Copy the content of the page from the original document to the new document.
• Save the resulting document using the Document.saveToFile() method.

package com.et.spire.doc;import com.spire.doc.*;
import com.spire.doc.pages.*;
import com.spire.doc.documents.*;public class ReadOnePage {public static void main(String[] args) {// Create a new document objectDocument document = new Document();// Load document content from the specified filedocument.loadFromFile("/Users/liuhaihua/tmp/WordDocument.docx");// Create a fixed layout document objectFixedLayoutDocument layoutDoc = new FixedLayoutDocument(document);// Get the first pageFixedLayoutPage page = layoutDoc.getPages().get(0);// Get the section where the page is locatedSection section = page.getSection();// Get the first paragraph of the pageParagraph paragraphStart = page.getColumns().get(0).getLines().getFirst().getParagraph();int startIndex = 0;if (paragraphStart != null) {// Get the index of the paragraph in the sectionstartIndex = section.getBody().getChildObjects().indexOf(paragraphStart);}// Get the last paragraph of the pageParagraph paragraphEnd = page.getColumns().get(0).getLines().getLast().getParagraph();int endIndex = 0;if (paragraphEnd != null) {// Get the index of the paragraph in the sectionendIndex = section.getBody().getChildObjects().indexOf(paragraphEnd);}// Create a new document objectDocument newdoc = new Document();// Add a new sectionSection newSection = newdoc.addSection();// Clone the properties of the original section to the new sectionsection.cloneSectionPropertiesTo(newSection);// Copy the content of the original document's page to the new documentfor (int i = startIndex; i <=endIndex; i++){newSection.getBody().getChildObjects().add(section.getBody().getChildObjects().get(i).deepClone());}// Save the new document to the specified filenewdoc.saveToFile("/Users/liuhaihua/tmp/Content of One Page.docx", FileFormat.Docx);// Close and release the new documentnewdoc.close();newdoc.dispose();// Close and release the original documentdocument.close();document.dispose();}
}
