If some rest controller are supported, please choose one solution:
- Use "@EnableImplicitApi" to decorate any class.
- Use "@Api" to decorate all controllers and all operations.
If you choose to add annotation `@EnableImplicitApi` to any class in
your REST web project, yet this problem still exists,
then the following possibilities may exist:
- There is no rest controller class
- Rest controller classes cannot be scanned by your web framework
- The web method is not public
