是否支持接口默认方法

default void setDeptName(List items, Function mapper, BiConsumer consumer) {
......
}

在接口中定义这样的默认方法，调用的时候报序列化错误

Reproduce the serialization error using the generic default method shown in the issue, first capturing the exact exception, Dubbo version, and serialization configuration. Then trace how interface default methods are handled during RPC serialization; done means the behavior is supported or the limitation is confirmed and clearly documented.
