Spring Boot Transaction Proxy Error When I call two transactional method as nested

Time：10-21

I have a service class like below. i call this "addPlayerToTeam" method from my controller class. This method has 3 operations:

1.control parameters and check data valid on my db (without transaction)

2.insert player to new team and create a history record (with transaction)

3.send notify to player for 'say hello' (without transaction)

But transactional method has a problem.

package com.thecodemakerz.transaction.service;

import lombok.extern.slf4j.Slf4j;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import com.thecodemakerz.transaction.domain.PlayerHistoryDto;
import com.thecodemakerz.transaction.domain.TeamPlayerDto;
import com.thecodemakerz.transaction.entity.Player;

@Service
@Slf4j
public class TeamPlayerServiceBestCase implements ITeamPlayerServiceBestCase {

  @Autowired
  private ITeamService teamService;

  @Autowired
  private IPlayerService playerService;

  @Autowired
  private IPlayerHistoryService historyService;

  @Autowired
  private IBildirimService bildirimService;


  @Override
  public Player addPlayerToTeam(TeamPlayerDto teamPlayerDto) {
    Player player = addPlayerToTeamControl(teamPlayerDto);
    player.setFkTeamId(teamPlayerDto.getFkTeamId());
    player = addPlayerToTeamInsert(player);
    sendNotifyAfterAddPlayerToTeam(player.getName());
    return player;
  }

  @Override
  public Player addPlayerToTeamControl(TeamPlayerDto teamPlayerDto) {
    log.info("addPlayerToTeamControl start");
    if (!teamService.existsById(teamPlayerDto.getFkTeamId())) {
      throw new RuntimeException("Team not found");
    }

    Player player = playerService.findById(teamPlayerDto.getFkPlayerId());
    if (player == null) {
      throw new RuntimeException("Player not found");
    }
    log.info("addPlayerToTeamControl end");
    return player;
  }

  @Override
  @Transactional
  public Player addPlayerToTeamInsert(Player player) {
    log.info("addPlayerToTeamInsert start");
    player = playerService.update(player);

    PlayerHistoryDto historyDto = new PlayerHistoryDto();
    historyDto.setFkPlayerId(player.getId());
    historyDto.setFkTeamId(player.getFkTeamId());
    historyService.addPlayerHistoryToNew(historyDto);
    log.info("addPlayerToTeamInsert end");
    return player;
  }

  @Override
  public void sendNotifyAfterAddPlayerToTeam(String playerName) {
    log.info("sendNotifyAfterAddPlayerToTeam start");
    bildirimService.sendMail();
    bildirimService.sendSms();
    bildirimService.sendPush();
    log.info("sendNotifyAfterAddPlayerToTeam end");
  }

}

playerService.update method is below and not contains class level or method level transaction

  @Override
  public Player update(Player player) {
    log.info("Player update işlemi yapılıyor");
    if (player == null || !existsById(player.getId())) {
      throw new RuntimeException("Player bulunamadı");
    }
    return playerRepo.save(player);
  }

historyService.addPlayerHistoryToNew method is below and not contains class level but has method level transaction as @Transactional(propagation = Propagation.MANDATORY)

  @Override
  @Transactional(propagation = Propagation.MANDATORY)
  public void addPlayerHistoryToNew(PlayerHistoryDto historyDto) {
    log.info("addPlayerHistoryToNew işlemi yapılıyor");
    update(historyDto);
    insert(historyDto);
  }

Following is the error result after running the method

BUT when I run the method as below, it works fine

@Override
  @Transactional
  public Player addPlayerToTeam(TeamPlayerDto teamPlayerDto) {

    if (!teamService.existsById(teamPlayerDto.getFkTeamId())) {
      throw new RuntimeException("İşlem yapılmak istenen Team bulunamadır");
    }

    Player player = playerService.findById(teamPlayerDto.getFkPlayerId());
    if (player == null) {
      throw new RuntimeException("İşlem yapılmak istenen Player bulunamadır");
    }

    player.setFkTeamId(teamPlayerDto.getFkTeamId());
    Player savedPlayer = playerService.update(player);

    PlayerHistoryDto historyDto = new PlayerHistoryDto();
    historyDto.setFkPlayerId(teamPlayerDto.getFkPlayerId());
    historyDto.setFkTeamId(teamPlayerDto.getFkTeamId());
    historyService.addPlayerHistoryToNew(historyDto);

    bildirimService.sendMail();
    bildirimService.sendSms();
    bildirimService.sendPush();

    return savedPlayer;
  }

Why am I getting an error in the proxy in the first example use? Does anyone know this? Can you help?

CodePudding user response：

When calling @Transactional methods from within the same component the proxy is not involved, and no transaction is started therefore. The @Transactional method has to be invoked from outside. (IMHO it's bad style to have several public methods that call each other.)
