Example 1 with FileMagic

use of org.apache.poi.poifs.filesystem.FileMagic in project hutool by looly.

the class ExcelFileUtil method getFileMagic.

/**
 * {@link java.io.PushbackInputStream}
 * PushbackInputStream的markSupported()为false，并不支持mark和reset
 * 如果强转成PushbackInputStream在调用FileMagic.valueOf(inputStream)时会报错
 * {@link FileMagic}
 * 报错内容：getFileMagic() only operates on streams which support mark(int)
 * 此处修改成 final InputStream in = FileMagic.prepareToCheckMagic(in)
 *
 * @param in {@link InputStream}
