Java如何使用Apache POI替换Microsoft Word文档中的文本？

下文笔者将讲述使用Apache POI替换Word文件中文本的方法及示例分享,如下所示

替换word文件中的文本，我们只需使用以下三种方法
   1.openDocument() 打开word文件
   2.replaceText()        替换文件中的内容
   3.saveDocument()   保存文件

例:Apache POI替换word文件中的内容

 
package com.java265.example.poi;

import org.apache.poi.hwpf.HWPFDocument;
import org.apache.poi.hwpf.usermodel.CharacterRun;
import org.apache.poi.hwpf.usermodel.Paragraph;
import org.apache.poi.hwpf.usermodel.Range;
import org.apache.poi.hwpf.usermodel.Section;
import org.apache.poi.poifs.filesystem.POIFSFileSystem;

import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.net.URL;

public class WordReplaceText {
    private static final String SOURCE_FILE = "test.doc";
    private static final String OUTPUT_FILE = "new-test.doc";

    public static void main(String[] args) throws Exception {
        WordReplaceText instance = new WordReplaceText();
        HWPFDocument doc = instance.openDocument(SOURCE_FILE);
        if (doc != null) {
            doc = instance.replaceText(doc, "java265.com", "我是被替换后的文本");
            instance.saveDocument(doc, OUTPUT_FILE);
        }
    }

    private HWPFDocument replaceText(HWPFDocument doc, String findText, String replaceText) {
        Range r = doc.getRange();
        for (int i = 0; i < r.numSections(); ++i) {
            Section s = r.getSection(i);
            for (int j = 0; j < s.numParagraphs(); j++) {
                Paragraph p = s.getParagraph(j);
                for (int k = 0; k < p.numCharacterRuns(); k++) {
                    CharacterRun run = p.getCharacterRun(k);
                    String text = run.text();
                    if (text.contains(findText)) {
                        run.replaceText(findText, replaceText);
                    }
                }
            }
        }
        return doc;
    }

    private HWPFDocument openDocument(String file) throws Exception {
        URL res = getClass().getClassLoader().getResource(file);
        HWPFDocument document = null;
        if (res != null) {
            document = new HWPFDocument(new POIFSFileSystem(
                new File(res.getPath())));
        }
        return document;
    }

    private void saveDocument(HWPFDocument doc, String file) {
        try (FileOutputStream out = new FileOutputStream(file)) {
            doc.write(out);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
