用java替换word文档模板中的变量

Question

我想加载一个模板word文档以添加内容并另存为新文档。我在处理.文件。

经过长时间的研究，我只找到了docx的解决方案：

所以我想用它的值替换以这种格式编写的任何变量:$var。我可以用velocity或Apache-poi来做它，什么是它的最佳解决方案。任何帮助都将不胜感激。

是的，您可以使用Apache-POI来完成。变量名必须唯一。请参阅以下代码

import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
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;

public class HWPFTest {
    public static void main(String[] args){
        String filePath = "F:\\Sample.doc";
        POIFSFileSystem fs = null;        
        try {            
            fs = new POIFSFileSystem(new FileInputStream(filePath));            
            HWPFDocument doc = new HWPFDocument(fs);
            doc = replaceText(doc, "$VAR", "MyValue1");
            saveWord(filePath, doc);
        }
        catch(FileNotFoundException e){
            e.printStackTrace();
        }
        catch(IOException e){
            e.printStackTrace();
        }
    }

    private static HWPFDocument replaceText(HWPFDocument doc, String findText, String replaceText){
        Range r1 = doc.getRange(); 

        for (int i = 0; i < r1.numSections(); ++i ) { 
            Section s = r1.getSection(i); 
            for (int x = 0; x < s.numParagraphs(); x++) { 
                Paragraph p = s.getParagraph(x); 
                for (int z = 0; z < p.numCharacterRuns(); z++) { 
                    CharacterRun run = p.getCharacterRun(z); 
                    String text = run.text();
                    if(text.contains(findText)) {
                        run.replaceText(findText, replaceText);
                    } 
                }
            }
        } 
        return doc;
    }

    private static void saveWord(String filePath, HWPFDocument doc) throws FileNotFoundException, IOException{
        FileOutputStream out = null;
        try{
            out = new FileOutputStream(filePath);
            doc.write(out);
        }
        finally{
            out.close();
        }
    }
}
