質問があります。Spring+Hibernate を使用していますが、 @Transactionalとしてマークされたメソッドで例外を処理できません。以前、Spring JDBC を使用したときは、すべて問題なく動作していました。
DAO クラスは @Repository でマークされます。
これが私の古いコードのスニッパーです。
使用中:
@Transactional(readOnly = false, propagation = Propagation.REQUIRES_NEW, rollbackFor = {Exception.class})
public boolean bookTickets(Integer userId, List<Integer> ticketsId) throws TicketsServiceException {
Integer currId = null;
try {
for (Integer ticketId : ticketsId) {
currId = ticketId;
Ticket ticket = ticketDAO.getTicketById(ticketId);
bookingDAO.bookTicket(ticket, userId);
}
} catch (DuplicateKeyException e) {
throw new TicketsServiceException(String.format(MESSAGE_TICKET_ALREADY_BOOKED, currId));
} catch (EmptyResultDataAccessException e) {
throw new TicketsServiceException(String.format(MESSAGE_NO_SUCH_TICKET, currId));
}
return true;
ダオで:
@Transactional(propagation = Propagation.MANDATORY)
public void bookTicket(Ticket ticket, final int userId) {
MapSqlParameterSource map = new MapSqlParameterSource();
map.addValue(Constants.TABLE_BOOKING.FIELD_TICKET_ID, ticket.getId());
map.addValue(Constants.TABLE_BOOKING.FIELD_USER_ID, userId);
int rowsAffected = template.update(QUERY_INSERT_BOOKING, map);
if (LOG.isTraceEnabled()) {
LOG.trace("Affected " + rowsAffected + " rows.");
}
}
今、私は DAO を Spring JDBC から hibernate 3 に移動しています。それが今の私です。
使用中:
@Transactional(readOnly = false, propagation = Propagation.REQUIRES_NEW, rollbackFor = {Exception.class})
public boolean bookTickets(Integer userId, List<Integer> ticketsId) throws TicketsServiceException {
Integer currId = null;
try {
for (Integer ticketId : ticketsId) {
currId = ticketId;
Ticket ticket = ticketDAO.getTicketById(ticketId);
bookingDAO.bookTicket(new Booking(ticketId, userId));
}
} catch (Exception e) {
throw new TicketsServiceException(String.format(MESSAGE_THERE_IS_NO_SUCH_TICKET_OR_ALREADY_BOOKED, currId));
}
return true;
}
ダオで:
@Override
public void bookTicket(Booking booking) {
getHibernateTemplate().save(booking);
}
問題は、サービス メソッドの try-catch ブロック内で例外を処理できないことです。彼らは私のコントローラーに直接投げています。
この問題は、Spring JDBCのトランザクション マネージャーorg.springframework.jdbc.datasource.DataSourceTransactionManagerと休止状態のorg.springframework.orm.hibernate3.HibernateTransactionManagerの違いにあると思いますが、この問題を克服する方法がわかりません。あなたの助け。
更新後。例外の例を追加。

サービス層内で例外を処理する方法はありますか?
ありがとうございました。
