Bean:

@Entity 
@Table(name = "topics") 
public class TopicBean implements Serializable { 

    @Id 
    @Column(name = "id") 
    @GeneratedValue(strategy = GenerationType.IDENTITY) 
    private Long id; 

    @Column(name = "topicId") 
    private String topicId; 
    @Column(name = "title") 
    private String title; 
    @Column(name = "details") 
    private String details; 
    @Column(name = "username") 
    private String username; 
    @Column(name = "userImage") 
    private String userImage; 
    @Column(name = "dayPosted") 
    private String dayPosted; 
}

Repository:

@Component 
public class TopicRepositoryImpl implements TopicService { 

    @Autowired 
    private TopicRepository topicRepository; 

    @Override 
    public TopicBean findByTopicId(String id) { 
     return topicRepository.findByTopicId(id); 
    } 

    Page<TopicBean> findAllByPage(Pageable pageable); 

}

Service:

TopicBean findById(long id); 

List<TopicBean> findByUsername(String name); 

List<TopicBean> findTop10ByUsername(String name); 

void saveTopic(TopicBean topicBean); 

void updateTopic(TopicBean topicBean); 

TopicBean findByTopicId(String id); 

void deleteTopicById(long id); 

Long deleteByTopicId(String id); 

Page<TopicBean> findAllByPage(Pageable pageable); 

void deleteAllTopics(); 

public boolean isTopicExist(TopicBean topicBean);

service Impl:

@Component 
public class TopicRepositoryImpl implements TopicService { 

    @Autowired 
    private TopicRepository topicRepository; 

    @Override 
    public TopicBean findByTopicId(String id) { 
     return topicRepository.findByTopicId(id); 
    } 

    @Override 
    public Page<TopicBean> findAllByPage(Pageable pageable) { 
     return topicRepository.findAll(pageable); 
    } 
}

Si je ne me trompe pas, je reçois cette erreur après avoir changé le nom de la classe de TopicServiceImpl à TopicRepositoryImpl

je devais changer le nom de la classe à cause de cela issue

Alors, comment puis-je résoudre ce problème?

Votre ID doit être un 'Long', pas un' String'. (Et vous pouvez ignorer votre TopicRepositoryImpl entier et TopicService si c'est tout ce qu'ils font.Avec 'DomainClassConverter', vous pouvez même simplement dire' @PathVariable TopicBean beanId' et Spring fera tout cela pour vous.) – chrylis

@chrylis il y a d'autres impl de service similaires dans cette classe de service que je n'ai pas inclus. – kittu

@chrylis a mis à jour la classe de service. J'utilise ID personnalisé (ID de sujet) dans la table dans la base de données avec ID normal. Le problème pourrait être avec ID n'étant pas Long? – kittu

Vous obtenez une exception StackOverflowException parce que vous avez une boucle infinie dans votre code. Notez que le suivant répète:

at seconds47.serviceImpl.TopicRepositoryImpl.findByTopicId(TopicRepositoryImpl.java:77) ~[classes/:?]

Votre code semble un peu clair car il semble que vous avez mis à jour le code, mais pas ici. Il semble que votre interface TopicService étend TopicRepository, ce service se référant lui-même.
