Main class

@SpringBootApplication
public class RestBootApplication {

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

controller

@Controller
public class HelloController {

    @RequestMapping("/hello")
    String helloWorld(){
        return "helloWorld";
    }

}

Trying to run in spring package. it always stops after starting up. I even added "spring-boot-starter-web" after looking at some questions with stackoverflow, but still encounters this problem.

Please, can you point out a problem to someone.

Answer 1

This happened to me, and it turned out to be a corrupted maven apache repository.
