SpringBoot [스프링부트] 시작하기(11) League 내부 로직 만들기

Member와 Team을 만들었던 것과 비슷하므로 추가적인 개념이 있을 경우만 설명하겠습니다.

LeagueHost == League의 요구사항과 같다고 볼 수 있습니다.

• LeagueHost는 League를 개최할 수 있습니다.
• LeagueHost는 League 참가를 희망한 팀의 리스트를 확인할 수 있으며 수락이 가능합니다.

 

1. LeagueService, LeagueServiceImpl 추가

public interface LeagueService {
    Long createLeague(LeagueDto leagueDto, Long userId);
    void acceptLeague(Long requestLeagueId);
    List<RequestLeagueDto> findRequestList(Long leagueId);
    List<RestLeagueDto> findRestLeagueSeat();
    RestLeagueDto findLeagueByName(String leagueName);
}

package com.example.league.service;
 
 
import com.example.league.domain.League;
import com.example.league.domain.ROLE;
import com.example.league.domain.Team;
import com.example.league.domain.User;
import com.example.league.domain.request.RequestLeague;
import com.example.league.dto.LeagueDto;
import com.example.league.dto.RequestLeagueDto;
import com.example.league.dto.RestLeagueDto;
import com.example.league.exception.*;
import com.example.league.repository.LeagueRepository;
import com.example.league.repository.RequestLeagueRepository;
import com.example.league.repository.UserRepository;
import lombok.RequiredArgsConstructor;
import org.springframework.data.domain.Sort;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
 
import java.util.List;
import java.util.stream.Collectors;
 
@Service
@Transactional
@RequiredArgsConstructor
public class LeagueServiceImpl implements LeagueService{
 
    private final LeagueRepository leagueRepository;
    private final RequestLeagueRepository requestLeagueRepository;
    private final UserRepository userRepository;
    @Override
    public Long createLeague(LeagueDto leagueDto, Long userId) {
        User user = userRepository.findById(userId).get();
        checkDuplicateTeamName(leagueDto);
        League league = League.createLeague(leagueDto.getSize(), leagueDto.getName(),user);
        return leagueRepository.save(league).getId();
    }
 
    @Override
    public void acceptLeague(Long requestLeagueId) {
        RequestLeague requestLeague = requestLeagueRepository.findWithFetchJoinUserById(requestLeagueId).get();
        Team team = requestLeague.getTeam();
 
        if(requestLeague.getRequest()){
            throw new AlreadyAcceptTeamException("이미 승인이 완료된 신청입니다.");
        }
 
        if(team.getLeague()!=null){
            throw new AlreadyLeagueException("이미 리그에 참가하고 있습니다.");
        }
 
        requestLeague.acceptRequest();
        requestLeague.increaseLeagueSize();
    }
 
    @Override
    public List<RequestLeagueDto> findRequestList(Long leagueId) {
        return requestLeagueRepository.findByLeagueId(leagueId, Sort.by(Sort.Direction.DESC))
                .stream().map(a -> new RequestLeagueDto(a.getRequest(),a.getLeague().getLeagueName()))
                .collect(Collectors.toList());
    }
 
    @Override
    public List<RestLeagueDto> findRestLeagueSeat() {
        return leagueRepository.findByRestSeat().stream().map(a -> new RestLeagueDto(a.getLeagueName(),
                a.getScaleSize(),a.getNowSize())).collect(Collectors.toList());
    }
 
    @Override
    public RestLeagueDto findLeagueByName(String leagueName) {
        League league = leagueRepository.findByName(leagueName).orElseThrow(
                () -> {
                    throw new NotExistLeagueNameException("해당 이름의 리그는 없습니다.");
                }
        );
 
        return new RestLeagueDto(league.getLeagueName(),league.getScaleSize(),league.getNowSize());
 
    }
    private void checkDuplicateTeamName(LeagueDto leagueDto) {
        leagueRepository.findByName(leagueDto.getName()).ifPresent(
                a -> {
                    throw new DuplicateLeagueNameException("이미 같은 이름의 리그가 있습니다.");
                }
        );
    }
}

2. 예외 클래스 추가

public class AlreadyLeagueException extends RuntimeException{
    public AlreadyLeagueException() {
        super();
    }
 
    public AlreadyLeagueException(String message) {
        super(message);
    }
 
    public AlreadyLeagueException(String message, Throwable cause) {
        super(message, cause);
    }
 
    public AlreadyLeagueException(Throwable cause) {
        super(cause);
    }
 
    protected AlreadyLeagueException(String message, Throwable cause, boolean enableSuppression, boolean writableStackTrace) {
        super(message, cause, enableSuppression, writableStackTrace);
    }
}

public class AlreadyAcceptTeamException extends RuntimeException{
    public AlreadyAcceptTeamException() {
        super();
    }
 
    public AlreadyAcceptTeamException(String message) {
        super(message);
    }
 
    public AlreadyAcceptTeamException(String message, Throwable cause) {
        super(message, cause);
    }
 
    public AlreadyAcceptTeamException(Throwable cause) {
        super(cause);
    }
 
    protected AlreadyAcceptTeamException(String message, Throwable cause, boolean enableSuppression, boolean writableStackTrace) {
        super(message, cause, enableSuppression, writableStackTrace);
    }
}

public class DuplicateLeagueNameException extends RuntimeException {
    public DuplicateLeagueNameException() {
        super();
    }
 
    public DuplicateLeagueNameException(String message) {
        super(message);
    }
 
    public DuplicateLeagueNameException(String message, Throwable cause) {
        super(message, cause);
    }
 
    public DuplicateLeagueNameException(Throwable cause) {
        super(cause);
    }
 
    protected DuplicateLeagueNameException(String message, Throwable cause, boolean enableSuppression, boolean writableStackTrace) {
        super(message, cause, enableSuppression, writableStackTrace);
    }
}

public class NotExistLeagueNameException extends RuntimeException{
    public NotExistLeagueNameException() {
        super();
    }
 
    public NotExistLeagueNameException(String message) {
        super(message);
    }
 
    public NotExistLeagueNameException(String message, Throwable cause) {
        super(message, cause);
    }
 
    public NotExistLeagueNameException(Throwable cause) {
        super(cause);
    }
 
    protected NotExistLeagueNameException(String message, Throwable cause, boolean enableSuppression, boolean writableStackTrace) {
        super(message, cause, enableSuppression, writableStackTrace);
    }
}

public class NotHaveAuthorityMakeLeagueException extends RuntimeException{
    public NotHaveAuthorityMakeLeagueException() {
        super();
    }
 
    public NotHaveAuthorityMakeLeagueException(String message) {
        super(message);
    }
 
    public NotHaveAuthorityMakeLeagueException(String message, Throwable cause) {
        super(message, cause);
    }
 
    public NotHaveAuthorityMakeLeagueException(Throwable cause) {
        super(cause);
    }
 
    protected NotHaveAuthorityMakeLeagueException(String message, Throwable cause, boolean enableSuppression, boolean writableStackTrace) {
        super(message, cause, enableSuppression, writableStackTrace);
    }
}

public class OverMaxLeagueSizeException extends RuntimeException{
    protected OverMaxLeagueSizeException(String message, Throwable cause, boolean enableSuppression, boolean writableStackTrace) {
        super(message, cause, enableSuppression, writableStackTrace);
    }
 
    public OverMaxLeagueSizeException() {
        super();
    }
 
    public OverMaxLeagueSizeException(String message) {
        super(message);
    }
 
    public OverMaxLeagueSizeException(String message, Throwable cause) {
        super(message, cause);
    }
 
    public OverMaxLeagueSizeException(Throwable cause) {
        super(cause);
    }
}

 

3. LeagueRepository 추가

@Query("select l from League l where l.leagueName= :leagueName")
Optional<League> findByName(@Param("leagueName") String leagueName);
 
@Query("select l from League  l where l.scaleSize>l.nowSize")
List<League> findByRestSeat();

 

4. LeagueRequestRepository 추가

@Query("select re from RequestLeague re join fetch re.team where re.id= :requestId")
Optional<RequestLeague> findWithFetchJoinUserById(@Param("requestId")Long requestId);
 
@Query("select re from RequestLeague  re join fetch re.league join fetch re.team where re.league.id= :leagueId")
List<RequestLeague> findByLeagueId(@Param("leagueId") Long leagueId);

5. Test 코드

League는 Team, Member와 매우 유사하므로 이미 설명한 부분들에 대해선 언급을 하지 않았습니다. 다음으로는 LeagueController, Interceptor, controllerAdvice를 만들어보겠습니다. 감사합니다.
