[apache/dubbo]建议设置默认序列化为java原生序列化方法

报错信息，能贴给我们看看么

@OneSourceCat DemoServer 这个服务的代码

确实hessian序列化不太好

dubbo hessian序列化发现在父类子类存在同名字段的情况下，如果父类的值为null的话，子类的同名字段赋值都会被覆盖为null

serialization=“java”，好用多了

没发现过，是不是把hibernate对象传输了？

@teaey Bean（远程方法返回的Bean） ----result(List<Map<String, Object>>) --------如果上面的map里面放入个class键，值为对方没有的类名，会报错，有官方解释么？ ----count(int) 类似这样： { "count": 1, "result": [ { "createTime": "2016-11-25 17:08:10", "status": 2, "class": "com.xxx.Xxx" } ] }

备注一下。

dubbo hessian序列化发现在父类子类存在同名字段的情况下，如果父类的值为null的话，子类的同名字段赋值都会被覆盖为null

This is fixed in latest version.

Now the kyro,fastjson serialization component is added
