springboot读取文件,打成jar包后访问不到的解决

public void test() {
  List<String> names = new ArrayList<>();
  InputStreamReader read = null;
  try {
   ClassPathResource resource = new ClassPathResource("name.txt");
 
   InputStream inputStream = resource.getInputStream();
   read = new InputStreamReader(inputStream, "utf-8");
   BufferedReader bufferedReader = new BufferedReader(read);
   String txt = null;
   while ((txt = bufferedReader.readLine()) != null) {
    if (StringUtils.isNotBlank(txt)) {
     names.add(txt);
    }
   }
  } catch (Exception e) {
   e.printStackTrace();
  } finally {
   if (read != null) {
    try {
     read.close();
    } catch (IOException e) {
     e.printStackTrace();
    }
   }
  }
 }

File file = ResourceUtils.getFile("classpath:static/image/image");

 ClassPathResource cpr = new ClassPathResource("static/image/image/kpg");
 InputStream in = cpr.getInputStream();

 public class ResourceRenderer {
 public static InputStream resourceLoader(String fileFullPath) throws IOException {
        ResourceLoader resourceLoader = new DefaultResourceLoader();
        return resourceLoader.getResource(fileFullPath).getInputStream();
    }
}

InputStream in = ResourceRenderer.resourceLoader("classpath:static/image/image");
