Converting null object Gson to Json

Question

I've been using Google's Gson API for quite some time and love its simplicity.

Nonetheless, I've found (probably) a bug on the toJson method.

When I try to convert a null object to JSON , instead of an exception, or alternatively a null String return, I get a String with the value null .

Do you consider this a bug?

Answer 1

否， null是有效的JSON值。

Answer 2

null在转换时不会产生NullPointerException ，因为它是文字且有效的Gson值。
