GWT通过RPC发送对象类型

问题描述

我正在尝试这样做

服务接口:

Boolean SaveObjectIntoDatabase(Object Entity);

ServiceAsync:

ServiceAsync:

void SaveObjectIntoDatabase(Object Entity,AsyncCallback <Boolean> Callback);

然后在serviceimpl上实现它

then implementing it on the serviceimpl

没有成功.

是不能通过GWT RPC发送类型为object的变量吗?

Is it that we cannot send a variable of type object via GWT RPC??

堆栈跟踪:

onModuleLoad() threw an exception

推荐答案

使对象类本身实现可序列化接口

make the object class itself implmenets serialisable interface
