SSH三大框架整合项目中的错误

Question

错误（并不是int非包装类型之类的问题）：

HTTP Status 500 - exception setting property value with CGLIB (set hibernate.cglib.use_reflection_optimizer=false for more info) setter of com.qst.giftems.gift.pojos.TGift.setTypeId; nested exception is org.hibernate.PropertyAccessException: exception setting property value with CGLIB (set hibernate.cglib.use_reflection_optimizer=false for more info) setter of com.qst.giftems.gift.pojos.TGift.setTypeId
