我试图将LinkedHashMap序列化为ObjectOutputStream，但遇到了一些奇怪的情况。ObjectOutputStream，将LinkedHashMap转换为Object，但它不是LinkedHashMap，它被写为我的类SQLRow？!

Host.instance.getLogger().info("Sending back player data...");
final LinkedHashMap<String, NetworkedSQLObject> hm = MirageSQLTables.players.getByPrimaryKey(rest.readUTF()).getAsSocketEligibleMap();
Host.instance.getLogger().info("Linked Hash Map class name: " + hm.getClass().getName());
c.sendMessage(new SQLObjectResponsePacket(pID, (Object)hm));

注意：函数getByPrimaryKey()是一个自定义SQL函数，它返回我的自定义类SQLRow。
上面代码的输出：

14:37:03 [INFO] [Host] Sending back player data...
14:37:03 [INFO] [Host] Getting col: id
14:37:03 [INFO] [Host] Getting col: name

它在NetworkedSQLObject构造函数中说明了同样的事情。函数getAsSocketEligibleMap()在SQLRow类内部，但我真的很困惑，因为它与类没有关系，并返回一个新的LinkedHashMap，而不是SQLRow的示例...
getAsSocketEligibleMap()代码：

public LinkedHashMap<String, NetworkedSQLObject> getAsSocketEligibleMap(){
        return new LinkedHashMap<>(){{
            Set<Map.Entry<String, SQLObject>> es = data.entrySet();

            Iterator<Map.Entry<String, SQLObject>> i = es.iterator();

            while(i.hasNext()){
                Map.Entry<String, SQLObject> entry = i.next();
                Host.instance.getLogger().info("adding NetworkedSQLObject: " + entry.getKey() + ':' + entry.getValue().getType() + " -> " + entry.getValue().getValue());
                put(entry.getKey(), new NetworkedSQLObject(entry.getValue()));
            }
        }};
    }

任何帮助都很感激…
