Java代码替换Word文件中指定字符的流程

  1. 打开Word文件
  2. 读取Word文件的内容
  3. 替换指定字符
  4. 保存修改后的Word文件

    A[打开Word文件] --> B[读取文件内容]
    B --> C[替换指定字符]
    C --> D[保存修改后的Word文件]

代码示例

  1. 打开Word文件使用Apache POI库的方法:
import org.apache.poi.xwpf.usermodel.XWPFDocument;
import org.apache.poi.xwpf.usermodel.XWPFParagraph;
import org.apache.poi.xwpf.usermodel.XWPFRun;

public void openWordFile(String filePath) {
    try {
        FileInputStream fis = new FileInputStream(filePath);
        XWPFDocument document = new XWPFDocument(fis);
        // 其他操作
        fis.close();
    } catch (IOException e) {
        e.printStackTrace();
    }
}
  1. 读取Word文件的内容:
public String readWordFile(XWPFDocument document) {
    StringBuilder content = new StringBuilder();
    List<XWPFParagraph> paragraphs = document.getParagraphs();
    for (XWPFParagraph paragraph : paragraphs) {
        content.append(paragraph.getText());
    }
    return content.toString();
}
  1. 替换指定字符:
public String replaceText(String content, String target, String replacement) {
    return content.replace(target, replacement);
}
  1. 保存修改后的Word文件:
public void saveWordFile(XWPFDocument document, String filePath) {
    try {
        FileOutputStream fos = new FileOutputStream(filePath);
        document.write(fos);
        fos.close();
    } catch (IOException e) {
        e.printStackTrace();
    }
}

完整代码示例

import org.apache.poi.xwpf.usermodel.XWPFDocument;
import org.apache.poi.xwpf.usermodel.XWPFParagraph;

import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.List;

public class WordUtils {

    public static void main(String[] args) {
        String filePath = "path/to/word/file.docx";
        String target = "oldText";
        String replacement = "newText";
        
        XWPFDocument document = openWordFile(filePath);
        String content = readWordFile(document);
        String modifiedContent = replaceText(content, target, replacement);
        saveWordFile(document, filePath);
    }

    public static XWPFDocument openWordFile(String filePath) {
        try {
            FileInputStream fis = new FileInputStream(filePath);
            XWPFDocument document = new XWPFDocument(fis);
            // 其他操作
            fis.close();
            return document;
        } catch (IOException e) {
            e.printStackTrace();
        }
        return null;
    }

    public static String readWordFile(XWPFDocument document) {
        StringBuilder content = new StringBuilder();
        List<XWPFParagraph> paragraphs = document.getParagraphs();
        for (XWPFParagraph paragraph : paragraphs) {
            content.append(paragraph.getText());
        }
        return content.toString();
    }

    public static String replaceText(String content, String target, String replacement) {
        return content.replace(target, replacement);
    }

    public static void saveWordFile(XWPFDocument document, String filePath) {
        try {
            FileOutputStream fos = new FileOutputStream(filePath);
            document.write(fos);
            fos.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

以上代码使用Apache POI库来操作Word文件,其中openWordFile方法用于打开Word文件,readWordFile方法用于读取文件内容,replaceText方法用于替换指定字符,saveWordFile方法用于保存修改后的Word文件。
