oh，I do not think add a new struct in dubbogo/hessian2 is a good idea. The
more definitions we create, the higher the learning cost of users. There
are slice and array in Golang which slice is a dynamic array . So why we
not create slice of interface{} type in go and arrayList (means a dynamic
array) in java mapping, array of interface{} type in go and object array
in java mapping ?
