스프링 부트가 URL을 찾지 못함

Integrating Angular 2 with Spring Boot, JWT and CORS, Part 1에서 튜토리얼을 실행하려고합니다. STS (Spring Tool Suite) 환경에서 컴파일되는 프로젝트를 가지고 있지만 사이트에서 권장하는 링크 http://localhost:8080/heroes과 통신하지 않습니다. 스프링 부트가 URL을 찾지 못함

나는 저자가 쓴 아무것도 변경하지 않도록 노력하고있어,하지만 난 는 다음과 같은 방법으로을했다 : data.sql를 들어

가 나는 CREATE TABLE 문을 앞에 추가. 이로써 H2 데이터베이스는 성공적으로 채워졌습니다.
RepositoryConfig.java와 HeroRepository.java를 영웅 패키지에 넣었습니다. 웹 사이트는 com.examples 패키지를 권장합니다.

내가 STS는 "실행 바와 같이", "봄 부팅 앱"명령이 나는 봄 부팅 출력에서 이러한 매핑을 얻을 실행되면 : 내가 선택하는 경우

을 http://localhost:8080 또는 http://localhost:8080/profile 내가 다시 뭔가를 얻을 HATEOAS 응답처럼 보입니다. 그러나 http://localhost:8080/heroes에서 시도하면 404 응답이 반환됩니다.

이 프로그램은 Hero, HeroRepository, RepositoryConfig 및 BackEndApplication의 네 가지 Java 파일 만 가지고 있습니다.

@RepositoryRestResource(collectionResourceRel = "heroes", path = "heroes") 
public interface HeroRepository extends CrudRepository<Hero, Long> {

내가 작품을 만들기 위해 노력하고있어 튜토리얼 사이트가 중요한 비트를 누락 된 것으로 나타납니다 여기 HeroRepository의 시작입니다. 내가 뭘 놓치고 있니?

감사합니다. Jerome.

브라우저에서 http : // localhost : 8080에 도달하면 응답에 http : // localhost : 8080/heroes를 제공해야합니다. 그거 보여? – pvpkiran

아래 나의 대답을 참조하십시오. 나는 stackoverflow 대답을 찾았는데 문제는 무엇이며 어떻게해야 하는가? –

나는 도움을 주위를 둘러 보았다 및에 StackOverflow에 여기를 발견했습니다 Spring Boot: Cannot access REST controller on localhost (404)

튜토리얼 코드의 문제점은 @SpringBootApplication의 클래스가 "낮은"패키지의 점이다 -에, 다른 하나 최소한 - REST 클래스가있는 코드의 것보다. 튜토리얼에서는 영웅을 의미합니다. backend.BackEndApplication은 프로그램이 영웅을 찾도록하지 않습니다 .HeroRepository.

{ 
    "_links" : { 
    "self" : { 
     "href" : "http://localhost:8080/profile" 
    }, 
    "heroes" : { 
     "href" : "http://localhost:8080/profile/heroes" 
    } 
    } 
}

듣기 주셔서 감사합니다, pvpkiran, 회신 주셔서 감사합니다 :

나는 heroes.BackEndApplication을하고 성공을 할 수있는 클래스를했다.

제롬.
