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 object
        Document doc = new Document();

        //Add a section
        Section section = doc.addSection();

        //Set the page margins
        section.getPageSetup().getMargins().setAll(40f);

        //Add a paragraph as title
        Paragraph titleParagraph = section.addParagraph();
        titleParagraph.appendText("Introduction of Spire.Doc for Java");

        //Add two paragraphs as body
        Paragraph 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 paragraph
        ParagraphStyle 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 paragraphs
        ParagraphStyle 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 paragraphs
        titleParagraph.getFormat().setHorizontalAlignment(HorizontalAlignment.Center);
        bodyParagraph_1.getFormat().setHorizontalAlignment(HorizontalAlignment.Justify);
        bodyParagraph_2.getFormat().setHorizontalAlignment(HorizontalAlignment.Justify);

        //Set the first line indent
        bodyParagraph_1.getFormat().setFirstLineIndent(30) ;
        bodyParagraph_2.getFormat().setFirstLineIndent(30);

        //Set the after spacing
        titleParagraph.getFormat().setAfterSpacing(10);
        bodyParagraph_1.getFormat().setAfterSpacing(10);

        //Save to file
        doc.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 object
        Document document = new Document();

        // Load a sample document from a file
        document.loadFromFile("/Users/liuhaihua/tmp/WordDocument.docx");

        // Get the body of the last section of the document
        Body body = document.getLastSection().getBody();

        // Insert a page break after the last paragraph in the body
        body.getLastParagraph().appendBreak(BreakType.Page_Break);

        // Create a new paragraph style
        ParagraphStyle 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 collection
        document.getStyles().add(paragraphStyle);

        // Create a new paragraph and set the text content
        Paragraph 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 style
        paragraph.applyStyle(paragraphStyle.getName());

        // Add the paragraph to the body's content collection
        body.getChildObjects().add(paragraph);

        // Create another new paragraph and set the text content
        paragraph = 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 sales@e-iceblue.com, and we will send the license to you within one working day.");

        // Apply the paragraph style
        paragraph.applyStyle(paragraphStyle.getName());

        // Add the paragraph to the body's content collection
        body.getChildObjects().add(paragraph);

        // Save the document to a specified path
        document.saveToFile("/Users/liuhaihua/tmp/Add a Page.docx", FileFormat.Docx);

        // Close the document
        document.close();

        // Dispose of the document object's resources
        document.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 object
        Document document = new Document();

        // Load document content from the specified file
        document.loadFromFile("/Users/liuhaihua/tmp/WordDocument.docx");

        // Create a fixed layout document object
        FixedLayoutDocument layoutDoc = new FixedLayoutDocument(document);

        // Get the first page
        FixedLayoutPage page = layoutDoc.getPages().get(0);

        // Get the section where the page is located
        Section section = page.getSection();

        // Get the first paragraph of the page
        Paragraph paragraphStart = page.getColumns().get(0).getLines().getFirst().getParagraph();
        int startIndex = 0;
        if (paragraphStart != null) {
            // Get the index of the paragraph in the section
            startIndex = section.getBody().getChildObjects().indexOf(paragraphStart);
        }

        // Get the last paragraph of the page
        Paragraph paragraphEnd = page.getColumns().get(0).getLines().getLast().getParagraph();

        int endIndex = 0;
        if (paragraphEnd != null) {
            // Get the index of the paragraph in the section
            endIndex = section.getBody().getChildObjects().indexOf(paragraphEnd);
        }

        // Create a new document object
        Document newdoc = new Document();

        // Add a new section
        Section newSection = newdoc.addSection();

        // Clone the properties of the original section to the new section
        section.cloneSectionPropertiesTo(newSection);

        // Copy the content of the original document's page to the new document
        for (int i = startIndex; i <=endIndex; i++)
        {
            newSection.getBody().getChildObjects().add(section.getBody().getChildObjects().get(i).deepClone());
        }

        // Save the new document to the specified file
        newdoc.saveToFile("/Users/liuhaihua/tmp/Content of One Page.docx", FileFormat.Docx);

        // Close and release the new document
        newdoc.close();
        newdoc.dispose();

        // Close and release the original document
        document.close();
        document.dispose();
    }
}
