CodePudding user response:
The error is: could not findacceptable representation.In my local environment I run this code, without exception,
So I guess this may be because the spring version is different due to the problem,
I find from the Internet, the problem appeared in the version 3.2 and later, most of the 3.1 version without the problem,
Speculation method: add a return value to the method, the return value of short duration is not null;
If not, you can consult the blog
