如何转换ByteArrayOutputStream以便使用readline循环

ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
// 将数据写入ByteArrayOutputStream
...

// 将ByteArrayOutputStream转换为ByteArrayInputStream
ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(byteArrayOutputStream.toByteArray());

// 使用BufferedReader读取字节流
BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(byteArrayInputStream));
String line;
while ((line = bufferedReader.readLine()) != null) {
    // 处理每行数据
    ...
}

// 关闭流
bufferedReader.close();
byteArrayInputStream.close();
byteArrayOutputStream.close();
