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();    }}
