私はSpringとJPAの新機能です。TransactionRequiredExceptionに問題があります。私は（等手動で取引を開始、@Transactionalで注釈として）here、hereとhereを配置ヒントを試みJPA TransactionRequiredException
次のように私のコードは次のとおり
Goal.java
@Entity
@Table(name = "goals")
public class Goal
{
@Id
@GeneratedValue
@Column(name = "GOAL_ID")
private Long id;
@Range(min = 1, max = 120)
@Column(name = "MINUTES")
private int minutes;
public int getMinutes()
{
return minutes;
}
public void setMinutes(int minutes)
{
this.minutes = minutes;
}
public Long getId()
{
return id;
}
public void setId(Long id)
{
this.id = id;
}
}
をGoalRepositoryImpl.java
@Repository("goalRepository")
@Transactional
public class GoalRepositoryImpl implements IGoalRepository
{
@PersistenceContext
private EntityManager em;
public Goal save(Goal goal)
{
em.persist(goal);
return goal;
}
}
GoalServiceImpl.java
@Service("goalService")
public class GoalServiceImpl implements IGoalService
{
@Autowired
private IGoalRepository goalRepository;
@Transactional
public Goal save(Goal goal)
{
return goalRepository.save(goal);
}
}
GoalController
@Controller
@SessionAttributes("goal")
public class GoalController
{
@Autowired
private IGoalService goalService;
@RequestMapping(value = "/addGoal", method = RequestMethod.POST)
public String updateGoal(@Valid @ModelAttribute("goal") Goal goal, BindingResult result){
if (result.hasErrors()){
return "addGoal";
}else{
goalService.save(goal);
}
return "redirect:addMinutes.html";
}
}

リポジトリから '@ Transactional'を削除して、それが違いを生むかどうか確認してください。単一のトランザクション内で特定の作業単位に対して複数のリポジトリの対話が必要な場合があるため、実際にはトランザクションレベルの境界はサービスレベルではなくリポジトリレベルに存在する必要があります。 – Naros
私はそれを試みました。まだ運がありません。また、私のjpaContextに '
あなたは[ここ]（http://stackoverflow.com/questions/33781945/no-entitymanager-with-actual-transaction-available-for-current-thread-cannot-r）で遭遇したのと同じ問題を扱っている可能性があります。 –
