Answer 1

Post your request to localhost:8080/add/
Otherwise add a class level #RequestMapping annotation specifying the value of the endpoint.

Answer 2

Spring boot initializes the application the context of /. There's nothing mapped to /SpringRestfulWebServiceHibernate.
To have your request working, simply send a POST to /add/. (since you've mapped with the slash in the end of add/, you have to send exactly with this slash (/add/)).
Now, if you need the context of /SpringRestfulWebServiceHibernate to be used within your requests, simply put the following line in your application.properties:
server.servlet.context-path=/SpringRestfulWebServiceHibernate
