所以我在点击时写入数据库时出现问题。点击：我正在调用API，抓取数据，并写入数据库表。
我收到NotSerializableException异常，我相信这是因为我在点击中调用dao：
proImage.add(new AjaxEventBehavior("click") {
private static final long serialVersionUID = 1L;
@Override
protected void onEvent(AjaxRequestTarget target) {
try {
updateGamesPlayed(player.getSummonerId());
} catch (RiotApiException e) {
e.printStackTrace();
}
}
});
我的DAO应该可序列化吗？我以前遇到过这样的问题，但实际上并没有找到任何遗漏的东西＆＃34; Serializable＆＃34;。
这是堆栈跟踪：
