您不能添加字体...
你可以把你的（办公室）文件，就像HTML。字体住文档之外。你刚才设置的字体名称，家庭等。

更新：

不过，已经有人想这样做。使用嵌入的文件，你可以添加字体文件。

这并不容易。有没有简单的方法来插入嵌入的文件。

• 文件嵌入到Excel中使用Apache POI


• Embedding使用HSSF（EXCEL）到HSLF（PPT）的Apache POI

How can i import a new font to POI API with extensions ttf & otf , without install these fonts into the environment ?

Is there a jar that i should update it with the path of the new font ?

Normally

You cannot add fonts... You can think your (office) files just like HTML. Font lives outside the document. You just set the font name, family, etc.

Update:

However, someone has already tried to do that. Using embedded files, you could add font files.

It is far from easy. There's no easy way to insert embedded files.

• Embed files into Excel using Apache POI
• Embedding HSSF(excel) into HSLF(ppt) using apache poi
