在尝试加载带有Map的类时，我在使用Hibernate时遇到异常。
它没有，但是当我将这个字段添加到类中时，它会在标题中给出错误。
以下是类，Person，PhoneNumber，PersonServiceImpl和IPersonService。
所有这些似乎都没有Person.PhoneNumber字段。
有什么想法吗？
我的测试用例运行良好：
for (int i = 0; i < getIterations(); i++) {
entityManager.getTransaction().begin();
Person person = getPersonForIteration(i);
entityManager.persist(person);
entityManager.getTransaction().commit();
Person foundPerson = entityManager.find(Person.class,
person.getId());
doAssertsForFoundPerson(foundPerson, person);
}

答案 0 :(得分：2)
据我所知，类加载存在问题。我不确定它是什么，但当我降级到Hibernate 4.3.11时。最终的东西开始正常工作。
我不确定为什么，并且厌倦了想弄明白。一旦我切换了Hibernate的版本，一切都运转了。
