I encountered a problem when using spring mvc to implement restful api.
I use postman to test one method like this:
http://localhost:8080/Test/countryController/getAllCountries
- Test is the project name
- countryController is the value of @RequestMapping of controller class
- getAllCountries is the get method
However, I got an error message:
The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.
I searched for many posts, but still can't solve it. Hope anyone can help me.
Here is the code below.
