【spring源码学习】spring配置的事务方式是REQUIRED,但业务层抛出TransactionRequiredException异常问题

(1)spring抛出异常的点:org.springframework.orm.jpa.EntityManagerFactoryUtils

public static DataAccessException convertJpaAccessExceptionIfPossible(RuntimeException ex) {
        // Following the JPA specification, a persistence provider can also
        // throw these two exceptions, besides PersistenceException.
        if (ex instanceof IllegalStateException) {
            return new InvalidDataAccessApiUsageException(ex.getMessage(), ex);
        }
        if (ex instanceof IllegalArgumentException) {
            return new InvalidDataAccessApiUsageException(ex.getMessage(), ex);
        }

        // Check for well-known PersistenceException subclasses.
        if (ex instanceof EntityNotFoundException) {
            return new JpaObjectRetrievalFailureException((EntityNotFoundException) ex);
        }
        if (ex instanceof NoResultException) {
            return new EmptyResultDataAccessException(ex.getMessage(), 1, ex);
        }
        if (ex instanceof NonUniqueResultException) {
            return new IncorrectResultSizeDataAccessException(ex.getMessage(), 1, ex);
        }
        if (ex instanceof QueryTimeoutException) {
            return new org.springframework.dao.QueryTimeoutException(ex.getMessage(), ex);
        }
        if (ex instanceof LockTimeoutException) {
            return new CannotAcquireLockException(ex.getMessage(), ex);
        }
        if (ex instanceof PessimisticLockException) {
            return new PessimisticLockingFailureException(ex.getMessage(), ex);
        }
        if (ex instanceof OptimisticLockException) {
            return new JpaOptimisticLockingFailureException((OptimisticLockException) ex);
        }
        if (ex instanceof EntityExistsException) {
            return new DataIntegrityViolationException(ex.getMessage(), ex);
        }
                //抛出异常的点位
        if (ex instanceof TransactionRequiredException) {
            return new InvalidDataAccessApiUsageException(ex.getMessage(), ex);
        }

        // If we have another kind of PersistenceException, throw it.
        if (ex instanceof PersistenceException) {
            return new JpaSystemException(ex);
        }

        // If we get here, we have an exception that resulted from user code,
        // rather than the persistence provider, so we return null to indicate
        // that translation should not occur.
        return null;
    }
