Hibernate使用Gson时报错：org.hibernate.proxy.HibernateProxy. Forgot to register a type adapter?

主要是使用Hibernate查询的实体类有多对一的关系，Hibernate默认延迟加载，不会查询关联的实体一方，只有实际使用的时候才进行查询，导致Gson转Json时报错

改善方法：

一对多配置文件中加入 lazy="false"，我是给关联双方都加入了这句，就可以使用了

<set name="Linkmans" cascade="save-update" inverse="true" lazy="false" >
