下面直接贴出一个工具类VerifyClient.java

}

在src/main/ 下面新建slice文件夹，然后放入keeper_verify.ice 文件

[["java:package:com.XXX.XXX"]]
module verify 
{
    
    sequence<byte> ByteSeq;

    interface MessageReceiver 
    {
        void onMessage(string message, ByteSeq imageBuff);
    };

    dictionary<string, MessageReceiver*> DeviceList;
    
    interface KeeperServer 
    {
        bool login(string deviceID, MessageReceiver* receiver);
        void logout(string deviceID);
        void sendMessage(string deviceID, string message, ByteSeq imageBuff);
    };

};
