entityManager.persist（entity）hibernate Exception

Question

尝试使用entityManager.persist(entity)方法时，我遇到以下hibernate异常。我已确保在Date课程中正确格式化了所有Time或Show属性。

    }catch(Exception e){
        throw new AppException("DB Exception : Invalid Time Format");
    }
    show.setTicketPrice(ticketPrice);
    entityManager.persist(show); 
}

Answer 1

Show是一个保留的MySQL关键字。更改表的名称。
