Spring-Boot Docker This localhost page can’t be found

I'm doing a little project and I have this controller:

@RestController @RequestMapping("/user") public class UserController { @Value("${me}") private String name; private final UserService userService; @Autowired public UserController(UserService userService) { this.userService = userService; } @PostMapping public ResponseEntity<User> createUser(@RequestBody User user) { User created = userService.save(user); return new ResponseEntity<>(created, HttpStatus.CREATED); } @GetMapping("/hello") public String hello() { return "hello"; } @GetMapping("/me") public String me() { return "hello " + name; } @GetMapping("/{username}") public ResponseEntity<User> getUserByUsername(@PathVariable String username) { User user = userService.getByUsername(username); if (user != null) { return new ResponseEntity<>(user, HttpStatus.OK); } return new ResponseEntity<>(HttpStatus.NOT_FOUND); } } 

When working in localhost all my endpoints are working fine but when I dockerized it, "/hello" and "/me" endpoints return

**This localhost page can’t be foundNo webpage was found for the web address: http://localhost:8080/user/hello HTTP ERROR 404** 

What's the reason of it not working?

EDIT: I've been asked to add Dockerfile and here is my Dockerfile and docker-compose.yml:

FROM eclipse-temurin:17-jdk-alpine ARG JAR_FILE=target/*.jar COPY ./target/elasticSpring-0.0.1-SNAPSHOT.jar elasticSpring.jar ENTRYPOINT [ "java","-jar","/elasticSpring.jar" ] 

docker-compose.yml:

version: '1' services: es: image: docker.elastic.co/elasticsearch/elasticsearch:7.17.12 container_name: es ports: - 9200:9200 - 9300:9300 environment: - discovery.type=single-node networks: - mynet springboot-app: build: context: . dockerfile: Dockerfile container_name: springElastic ports: - 8080:8080 environment: - spring.elasticsearch.uris=es:9200 - spring.data.elasticsearch.cluster-nodes=es:9200 depends_on: - es networks: - mynet networks: mynet: driver: bridge 

And it works locally but when I start my application with docker-compose.yml endpoints "/user/hello" and "/user/me" says "This localhost page can’t be found" other endpoints work and has no problem.
