[GitHub] [dubbo-go-hessian2] jjhewlett opened a new issue #220: go-hessian2报错 error:decObject illegal object type tag:121

jjhewlett opened a new issue #220:
URL: https://github.com/apache/dubbo-go-hessian2/issues/220


   go-hessian2报错 error:decObject illegal object type tag:121
   
   我是Java服务端，dubbo-go是客户端。
   现在Data是java下发的一个List，list里每一个元素，都是实体对象
   下发单个没问题，下发list的就go-hessian2抛异常
   
   hessian.RegisterPOJO(&ResponseData{})
   type ResponseData struct {
   Code string
   Msg string
   Data interface{}
   }

   好像是一个JavaClassName 对应一个goName。
   不知道可不可以实现多个JavaClassName 对应一个goName呢

   @wongoo 
   目前还没有解决这个问题，我目前也很苦恼
   在JAVA服务层，我的DATA是个泛型。
   我尝试过go客户端的response data改成[]interface{},但是改成这样我的详情就直接抛相同的异常了。

   map有2个key,一个key是int，一个key是list
   该如何定义。才能够正常解析。

   @jjhewlett  more details needed, include java object definition, java test data, code sample.  And I guess, u only register ResponseData, but not for order object. u need register all objects.

   GetOrder这个方法返回的是一个order list
   GetOrderOne 返回的是一个order object
   响应的数据结构都是ResponseData

   因为Golang语法不支持泛型。已经将代码改成如下
