代码
主要工具类 需要引入依赖：

import java.util.regex.Pattern;public class StringExtractor {public static String extractID(String input) {// 定义正则表达式模式String pattern = "ID_[A-Z0-9]+";Pattern compiledPattern = Pattern.compile(pattern);Matcher matcher = compiledPattern.matcher(input);// 查找匹配的字符串if (matcher.find()) {return matcher.group();} else {return null;}}
}
测试：
package com.chenkang.demo.learn;import com.chenkang.demo.util.StringExtractor;
import com.chenkang.demo.util.WpsImageUtil;
import org.apache.poi.xssf.usermodel.XSSFPictureData;
import org.apache.poi.xssf.usermodel.XSSFSheet;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;import java.io.File;
import java.util.Map;/*** @author chenkang* @since 2024/6/6 14:09*/
public class LockLearn {public static void main(String[] args) throws Exception {File file = new File("C:\\Users\\18151\\Desktop\\test.xlsx");XSSFWorkbook sheets = new XSSFWorkbook(file);XSSFSheet sheetAt = sheets.getSheetAt(0);String id=sheetAt.getRow(1).getCell(1).getStringCellValue();Map<String, XSSFPictureData> pictureMap = WpsImageUtil.getPictureMap(sheets);System.out.println(pictureMap);System.out.println(pictureMap.get(StringExtractor.extractID(id)));}}项目需要引入依赖， 可以手动打入maven仓库帮助解析wps图片信息
