Getting “No message available” error with Spring Boot + REST application

Question

I have created demo Spring Boot project and implemented Restful services as shown here

@RestController
public class GreetingsController {
    @RequestMappin         


        

Answer 1

You're probably missing @SpringBootApplication:

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class Application {

    public static void main(String[] args) throws Exception {
        SpringApplication.run(Application.class, args);
    }
}

@SpringBootApplication includes @ComponentScan which scans the package it's in and all children packages. Your controller may not be in any of them.
