Spring REST Endpoint: 404 requested resource is not available error

Question

I created spring boot starter project with Rest application. When trying to run the application as Run on server it will redirect to web browser with URL till context-path but after adding endpoints and execute it will throw resource not available error. I tried out many but nothing helps.

Controller class:

package in.ineuron.controller;

import java.time.LocalDateTime;

import org.springframework.http.HttpStatus;    
import org.springframework.http.HttpStatusCode;    
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import in.ineuron.response.CurrencyResponse;

@RestController
@RequestMapping("/api/currency")
public class CurrencyController {

@GetMapping("/getCurrencyValue/from/{from}/to/{to}")
public ResponseEntity<CurrencyResponse> getCurrencyValue(@PathVariable String from,
        @PathVariable String to){
    CurrencyResponse response=new CurrencyResponse();
    response.setCurrencyId(1);
    response.setCurrencyFrom(from);
    response.setCurrencyTo(to);
    response.setCurrencyValue(82);
    return new ResponseEntity<CurrencyResponse>(response, HttpStatus.OK);   
}

@GetMapping("/wish")
public ResponseEntity<String> wishMessage(){
    LocalDateTime ldt=LocalDateTime.now();
    int hour=ldt.getHour();
    String body=null;
    if(hour<12)
        body="Good Morning";
    else if(hour<16)
        body="Good Noon";
    else if(hour<20)
        body="Good evening";
    else
        body="Good Night";
    return new ResponseEntity<String>(body, HttpStatus.OK);
    
}

}
