Protobuf快速入门实例2
编写程序，使用Protobuf完成如下功能
客户端可以随机发送Student PoJo/ Worker PoJo 对象到服务器 (通过 Protobuf 编码)
服务端能接收Student PoJo/ Worker PoJo 对象(需要判断是哪种类型)，并显示信息(通过 Protobuf 解码)
syntax = "proto3";
option optimize_for = SPEED; // 加快解析
option java_package="com.atguigu.netty.codec2"; //指定生成到哪个包下
option java_outer_classname="MyDataInfo"; // 外部类名, 文件名
//protobuf 可以使用message 管理其他的message
message MyMessage {
//定义一个枚举类型
enum DataType {
StudentType = 0; //在proto3 要求enum的编号从0开始
WorkerType = 1;
}
//用data_type 来标识传的是哪一个枚举类型
DataType data_type = 1;
//表示每次枚举类型最多只能出现其中的一个, 节省空间
oneof dataBody {
Student student = 2;
Worker worker = 3;
}
}
message Student {
int32 id = 1;//Student类的属性
string name = 2; //
}
message Worker {
string name=1;

}
