java - 将 Word 文档读入处理时出错

Question

我正在尝试从Word文件中读取文本数据，找到了以下Java答案的链接

How read Doc or Docx file in java?

我决定编写一些代码。

import java.io.*;
import org.apache.poi.hwpf.HWPFDocument;
import org.apache.poi.hwpf.extractor.WordExtractor;

String s = "C:\\Users\\admin\\Desktop\\doc.doc";

String []doc = null;


String [] func(String Loc){
  WordExtractor extractor = null;
  String s = "sketch_200318a\\";
  String [] fileData = null;
  File file = null;

        try{

            file = new File(Loc);
            FileInputStream fis = new FileInputStream(file.getAbsolutePath());

            HWPFDocument document = new HWPFDocument(fis);
            extractor = new WordExtractor(document);

            fileData = extractor.getParagraphText();

            for (int i = 0; i < fileData.length; i++){

                if (fileData[i] != null)System.out.println(fileData[i]);

            }}
            catch (Exception exep){
            //exep.printStackTrace();
        }
        return fileData;
};

void setup(){
  size(400,400);
  doc = func(s);
};

void draw(){
  background(51);

  fill(255);
  for(int i=0;i<doc.length;i++){
   text(doc[i],10,10+10*i); 
  }

};

但是此代码不起作用

并产生以下错误

java.lang.NoClassDefFoundError: org/apache/commons/math3/util/ArithmeticUtils

我是否可以理解我在某个地方缺少一些依赖项或库？

Answer 1

是的，它缺少一个库，poi 包含一个 lib 文件夹，需要将其添加到项目代码文件夹中。
