After Updating Name of The Entity ,Updated Entity Comes Last In The Json

Inside restController package

@PutMapping("update/{id}")
public void update(@RequestBody UpdateLanguagesRequest updateLanguages,int id) {
    this.languagesService.update(updateLanguages, id);
}

Inside language manager

@Override

public void update(UpdateLanguagesRequest updateLanguageRequest,int id) {
    // TODO Auto-generated method stub
    Languages language=this.languageRepository.findById(id).get();
    language.setName(updateLanguageRequest.getName());
    this.languageRepository.save(language);
    this.languageRepository.flush();
    //language=getLanguageById; 
}

After updatind spesific element(e.g id=2) in database it becomes enter image description here id 3 comes before than id 2 how can i fix this?(I did not add the other apis like get add that is because they are working without error)

Solution

  • I have taken a quick look at your repository, I'll show the two required modifications. You can add a findAllOrderByIdAsc method to your repository:

    public interface LanguagesRepository extends JpaRepository<Languages,Integer> {
 List<Languages> findAllByOrderByIdAsc();               
}

    and use it in your service layer instead like this:

    @Override
    public List<GetAllLanguagesResponses> getAllResponse() {
        // TODO Auto-generated method stub
        List<Languages> languages=this.languageRepository.findAllByOrderByIdAsc();
        //this.languageRepository.flush();
        List<GetAllLanguagesResponses>languageResponse=new ArrayList<>();
        for(Languages language:languages) {
            GetAllLanguagesResponses responseItem=new GetAllLanguagesResponses();
            responseItem.setId(language.getId());
            responseItem.setName(language.getName());
            languageResponse.add(responseItem);
        }   
        return languageResponse;    
        
    }
