记录org.springframework.beans.FatalBeanException：Could not copy property 'xxx' from source to target异常

Spring提供的BeanUtils.copyProperties()可以进行属性的拷贝，今天在做一个功能时将订单主表（OrdertMaster）里的属性拷贝到OrderDTO中时BeanUtils.copyProperties(orderMaster,orderDTO);报了异常，如下

org.springframework.beans.FatalBeanException: Could not copy property 'buyerAddress' from source to target; nested exception is java.lang.reflect.InvocationTargetException

异常提示不能将资源类（OrdertMaster）中的属性'buyerAddress’拷贝到目标类（OrdertDTO）中!!! 搜了下有人提示可能是source类中的属性和target类中的属性的类型不一致导致，提示不要使用基本类型要使用包装类。可我发现我的属性是String类型的，很显然这招可能对我不管用。。。突然偶向下看发现了这个Caused by: org.hibernate.LazyInitializationException: could not initialize proxy [com.xxxx.xxxx.dataobject.OrderMaster#1557719742516848694] - no Session。嗦嘎，这不是前几天遇到的懒加载存在时，没有session的异常吗。当时是在source类上加了@Proxy(lazy=false)后解决了问题，于是偶激动的在OrderMaster上增加了@Proxy(lazy=false)这个注解和属性值。哟西！问题解决了！仅此记录下自己的填坑过程！
