У меня есть метод в моей службе транзакций, который проверяет объект и сохраняет его. Во время этого сохранения предположим, что из-за мусорных данных в дочернем объекте возникает исключение DataException.
Будучи RuntimeException, Hibernate запускает откат. Это я проверил из журналов, как показано ниже.
Когда я ловлю исключение в своем действии, я вижу, что дочерний объект в сеансе имеет связанный с ним идентификатор. Почему это происходит?
Это вызывает проблему, когда пользователь исправляет значение и пытается снова сохранить объект, а спящий режим пытается обновить объект, выдает пакетное обновление StaleStateException.
Я нашел блог, в котором точно описана проблема http://www.jroller.com/hasant/entry/hibernate_saveorupdate_trap_for_web . Есть ли решение для этого, которое мне не хватает? Является ли использование слияния выходом? Поможет ли hibernate.use_identifier_rollback=true?
