在jar文件中运行时无法读取文件

InputStream inputStream = getClass().getClassLoader().getResourceAsStream("文件路径");

ZipInputStream zipInputStream = new ZipInputStream(new FileInputStream("jar文件路径"));
ZipEntry entry;
while ((entry = zipInputStream.getNextEntry()) != null) {
    if (entry.getName().equals("需要读取的文件名")) {
        // 将文件解压到临时目录
        FileOutputStream outputStream = new FileOutputStream("临时目录路径");
        byte[] buffer = new byte[1024];
        int length;
        while ((length = zipInputStream.read(buffer)) > 0) {
            outputStream.write(buffer, 0, length);
        }
        outputStream.close();
        break;
    }
}
zipInputStream.close();
