由于某些奇怪的原因，当我升级到Hibernate 4时，我遇到以下异常： HibernateException：找到对集合的共享引用
我有以下bean映射如下：

每当我在HibernateCustomerProduct bean上设置一个新集合时，我都会得到异常。这很奇怪，因为我的测试中只有一个集合，但它仍然抱怨已经有另一个集合了。怎么可能？我的测试如下所示：
product = new HibernateCustomerProduct();
product.setCreated(new Date());
product.setCreatedBy("Salomo");
product.setCustomerId(123L);
product.setName("IPhone");
product.setProductId(1l);
product.setProductType(ProductTypeCode.MOBILE_SUBSCRIPTION);
product.setServiceId("036545458874");
product.setServiceIdType(ServiceIdType.MAIN_PHONE_NUMBER);
product.setOrderId(24123l);
product.setOrderLineId(2412l);
final HibernateNumber number = new HibernateNumber();
number.setCreated(new Date());
number.setCreatedBy("sape");
number.setNumber("0642165348");
number.setProduct(product);
final Set<Number> numbers = new HashSet<Number>();
numbers.add(number);
product.setNumbers(numbers);
customerProductDao.save(product);
customerProductDao.flush();
有人知道我做错了什么吗？在Hibernate 3中，这很好用。
答案 0 :(得分：0)
这似乎与SessionFactory中引入的其他东西有关。使用@PrePersist注释时。注册监听器时，正常的东西不再正常工作，所以我们停止使用这些注释，而是使用Spring方面。
