[Seasar-user:16860] Re: [Teeda]tldファイルの自動読み込みに関する挙動について

[ohara]

宛）小林様


いつもお世話になっております
小原です


確認をしている際、問題に遭遇しました
HotDeploy且つRenderer内でS2Containerが管理しているオブジェクトを参照するとClassCastExceptionが発生します
（⇒■Stacktrace参照）
ちなみにjarファイルの中にtldを配置しても同様です

聞きたいこと
・そもそも、アクセス方法が間違っていれば教えてください（⇒■アクセス方法参照）
・RendererでS2Container経由のオブジェクトを扱えるよう修正することは可能でしょうか
・もし、難しいようであれば、よい回避策があれば教えてください。
　⇒Objectで受けてリフレクションでアクセスする等（ただ、楽な方法がありがたいです）

■アクセス方法
NG
        CommonRequestDto commonRequestDto =
SingletonS2Container.getComponent(CommonRequestDto.class);
        Map commonRequest       = BeanUtil.createProperties(commonRequestDto);
        int aaaaaa              = commonRequestDto.getAaaa();


OK
        Object commonRequestDto =
SingletonS2Container.getComponent(CommonRequestDto.class);
        Map commonRequest       = BeanUtil.createProperties(commonRequestDto);
        int aaaa                =
Integer.parseInt(commonRequest.get("aaaa").toString());


ここではDTOにアクセスしているが、他に、メソッド呼び出しも行いたい


以上、よろしくお願いします
