用Java替换Word文档模板中的变量
我想加载模板Word文档以向其添加内容并另存为新文档。我正在处理.doc文件。
经过长时间的研究,我仅找到docx的解决方案:

programatically-docx4j
http://www.sambhashanam.com/mail-merge-in-java-for-microsoft-word-document-
part-i/
因此,我想将以这种格式编写的任何变量替换为:$VAR
它的值。我可以使用Velocity或Apache-
poi做到这一点,什么是最好的解决方案?任何帮助将不胜感激。
回答:
是的,您可以使用Apache-POI做到这一点。您的变量名称必须唯一。看下面的代码
import java.io.FileInputStream;import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import org.apache.poi.hwpf.HWPFDocument;
import org.apache.poi.hwpf.usermodel.CharacterRun;
import org.apache.poi.hwpf.usermodel.Paragraph;
import org.apache.poi.hwpf.usermodel.Range;
import org.apache.poi.hwpf.usermodel.Section;
import org.apache.poi.poifs.filesystem.POIFSFileSystem;
public class HWPFTest {
public static void main(String[] args){
String filePath = "F:\\Sample.doc";
POIFSFileSystem fs = null;
try {
fs = new POIFSFileSystem(new FileInputStream(filePath));
HWPFDocument doc = new HWPFDocument(fs);
doc = replaceText(doc, "$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();
}
}
}
