使用java编辑.doc文件（WORD）时，NoClassDefFoundError：org / apache / poi / OldFileFormatException？

Question

我尝试用java编辑.doc文件（ WORD ）。我使用了Apache POI库，但结果是否定的。我有一个以前的文档（模板），我想替换一个特定的单词。 （例如，我可以用字符串替换“name”，无论我想要什么）。

这是我尝试使用的互联网示例：

import java.io.BufferedInputStream;
import java.io.BufferedOutputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.HashMap;
import java.util.Iterator;
import java.util.Set;
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.poifs.filesystem.POIFSFileSystem;

public class Prueba {
     public void searchAndReplace(String inputFilename,
                                 String outputFilename,
                                 HashMap<String, String> replacements) {        
        File inputFile = null;
        File outputFile = null;
        FileInputStream fileIStream = null;
        FileOutputStream fileOStream = null;
        BufferedInputStream bufIStream = null;
        BufferedOutputStream bufOStream = null;
        POIFSFileSystem fileSystem = null;
        HWPFDocument document = null;
        Range docRange = null;
        Paragraph paragraph = null;
        CharacterRun charRun = null;
        Set<String> keySet = null;

        int numParagraphs = 0;
        int numCharRuns = 0;
        String text = null;
        String key = null;
        String value = null;

        try {
            inputFile = new File(inputFilename);
            fileIStream = new FileInputStream(inputFile);
            bufIStream = new BufferedInputStream(fileIStream);
            fileSystem = new POIFSFileSystem(bufIStream);
            document = new HWPFDocument(fileSystem);

            docRange = document.getRange();
            numParagraphs = docRange.numParagraphs();

            keySet = replacements.keySet();

            for(int i = 0; i < numParagraphs; i++) {
                paragraph = docRange.getParagraph(i);
                text = paragraph.text();

                numCharRuns = paragraph.numCharacterRuns();
                for(int j = 0; j < numCharRuns; j++) {
                    charRun = paragraph.getCharacterRun(j);

                    text = charRun.text();
                    keySetIterator = keySet.iterator();
                    while(keySetIterator.hasNext()) {

                        key = keySetIterator.next();
                        if(text.contains(key)) {

                            value = replacements.get(key);
                            int start = text.indexOf(key);
                            charRun.replaceText(key, value, start);


                            docRange = document.getRange();
                            paragraph = docRange.getParagraph(i);
                            charRun = paragraph.getCharacterRun(j);
                            text = charRun.text();
                        }
                    }
                }
            }
            bufIStream.close();
            bufIStream = null;

            outputFile = new File(outputFilename);
            fileOStream = new FileOutputStream(outputFile);
            bufOStream = new BufferedOutputStream(fileOStream);
            document.write(bufOStream);
        }
        catch(IOException ex) {
            System.out.println("Caught an: " + ex.getClass().getName());
            System.out.println("Message: " + ex.getMessage());
            System.out.println("Stacktrace follows.............");
            ex.printStackTrace(System.out);
        }
        finally {
            if(bufIStream != null) {
                try {
                    bufIStream.close();
                    bufIStream = null;
                }
                catch(IOException ex) {
                }
            }
            if(bufOStream != null) {
                try {
                    bufOStream.flush();
                    bufOStream.close();
                    bufOStream = null;
                }
                catch(IOException ex) {

                }
            }
        }        
    }
    public static void main(String[] args) {
        Prueba replacer = new Prueba();

        HashMap<String, String> searchTerms = new HashMap<>();
        searchTerms.put("search term 1", "replacement term 1");
        searchTerms.put("search term 2", "replacement term 2");
        searchTerms.put("search term 3", "replacement term 3");
        searchTerms.put("search term 4", "replacement term 4");

        replacer.searchAndReplace("Document.doc", // Source Document
                "Replaced Document.doc", // Result Document
                searchTerms);                             // Search/replacement items
    }
}

当我执行我的代码时，错误是下一个：
