POJOのActionFormをsessionスコープでってもしかしてダメかも

調べてて気になったこと。
BeanValidatorFormが利用するWrapDynaBeanがSerializableを実装していないところ。

もしかしてシリアライズしようとしたらエラーになっちゃうとか・・・

ちょっとテストを作成

public class JikkenTest extends TestCase {

    public void testSerializeBeanValidatorForm() {
        BeanValidatorForm from = new BeanValidatorForm("文字列");
        BeanValidatorForm to = (BeanValidatorForm) deepCopy(from);

        assertEquals("文字列", ((WrapDynaBean) to.getDynaBean()).getInstance());
    }

    public Object deepCopy(Object o) {
        ByteArrayOutputStream bout = new ByteArrayOutputStream();
        ObjectOutputStream out = null;
        try {
            out = new ObjectOutputStream(bout);
            out.writeObject(o);
        } catch (IOException e) {
            throw new RuntimeException("out ", e);
        } finally {
            if (out != null) {
                try {
                    out.close();
                } catch (IOException e) {
                }
            }
        }
        byte[] bytes = bout.toByteArray();

        Object newObject = null;
        ObjectInputStream in = null;
        try {
            in = new ObjectInputStream(new ByteArrayInputStream(bytes));
            newObject = in.readObject();
        } catch (IOException e) {
            throw new RuntimeException("in ", e);
        } catch (ClassNotFoundException e) {
            throw new RuntimeException("in ", e);
        } finally {
            if (in != null) {
                try {
                    in.close();
                } catch (IOException e) {
                }
            }

        }

        return (Serializable) newObject;
    }

}

WrapDynaBeanが足をひっぱてる・・・

やっぱ、S2ContatinerでPOJOActionFormのインスタンスとスコープを決めて、struts-config.xml action-mappingのscope属性は無視がいいのかも。

うーん。
ちょっと思ったんだけど、もうひと工夫必要かも。
S2Containerが

    request.setAttribute("logonForm", pojoForm);

を行った後にStrutsが

    request.setAttribute("logonForm", new BeanValidatorForm(pojoForm));

みたいな感じで処理が行われて、メチャクチャになるのかも・・・
想像だから、本当は全然違う処理かもしれないけど。

ちょっと調べてみよう。
