Are Spring Controllers Thread-Safe

Question

I came upon this Controller example, and am wondering if it is thread-safe? I am wondering specifically about the gson instance variable.

import org.springframe         


        

Answer 1

Gson is definitely thread safe and was made this way back in 2008, so as long as your version is post that then it should be fine. I see no thread safety issues with your code. Although I would make the instance of Gson static.
