java - 警告：SQL（org.hibernate.engine.jdbc.spi.SqlExceptionHelper logExceptions）错误：1064，SQLState：42000

Question

当org.hibernate.engine.jdbc.spi.SqlExceptionHelper logExceptions我尝试删除休眠中的记录时，session.delete(cust) 请提供一些帮助。谢谢！
我试图检查 id 列的字段映射。并且在调用 delete 方法之前，id 与cust对象绑定。

  Configuration configuration = new Configuration().configure();
  SessionFactory factory = configuration.buildSessionFactory();
  Session session = factory.openSession();
  long id = 2;
  try {
    Transaction t = session.beginTransaction();
    Customer cust = (Customer) session.get(Customer.class, id);
    session.delete(cust);
    t.commit();
  } catch (HibernateException e) {
    System.out.println(e.getLocalizedMessage());
    session.getTransaction().rollback();
  }
}
