wesleyy :
I am writing a Spring Boot application. I have written a simple controller that gets invoked whenever the endpoint is hit, but it still returns status 404 and not the specified return value.
HelloController
@Controller
public class MessageRequestController {
@RequestMapping(method = RequestMethod.GET, value = "/hello", produces = "application/json")
public String hello() {
System.out.println("Hit me!");
return "Hello, you!";
}
}
Now whenever I call localhost:8080/hello, I see the console log "Hit me!", but "Hello, you!" is never returned. Postman outputs:
{
"timestamp": 1516953147719,
"status": 404,
"error": "Not Found",
"message": "No message available",
"path": "/hello"
}
Application.java
@SpringBootApplication
@ComponentScan({"com.sergialmar.wschat"}) // this is the root package of everything
@EntityScan("com.sergialmar.wschat")
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
Saravana :
Change your method return a ResponseEntity<T>
@RequestMapping(method = RequestMethod.GET, value = "/hello", produces = "application/json")
public ResponseEntity<String> hello() {
System.out.println("Hit me!");
return new ResponseEntity<String>("Hello, you!", HttpStatus.OK);
}
or change the controller to RestController
@RestController
public class MessageRequestController {...}
CURL
ubuntu:~$ curl -X GET localhost:8080/hello
Hello, you!
