// Set the onTurnError for the singleton CloudAdapter.

// Define a state store for your bot. See https://aka.ms/about-bot-state to learn more about using MemoryStorage.
// A bot requires a state store to persist the dialog and user state between messages.

// For local development, in-memory storage is used.

Java SDK では、AdapterWithErrorHandler クラスは com.microsoft.bot.integration パッケージ内の SDK の一部として含まれています。 アダプターの onTurnError ハンドラーは、例外情報を含むトレース アクティビティを作成して、エミュレーターに送信します。 既定のアダプターのソース コードを以下に示します。

AdapterWithErrorHandler.java

setOnTurnError((turnContext, exception) -> {
    LoggerFactory.getLogger(AdapterWithErrorHandler.class).error("onTurnError", exception);


    return turnContext.sendActivities(
        MessageFactory.text(ERROR_MSG_ONE), MessageFactory.text(ERROR_MSG_TWO)
    ).thenCompose(resourceResponse -> sendTraceActivity(turnContext, exception))
        .thenCompose(stageResult -> {
            if (withConversationState != null) {
                // Delete the conversationState for the current conversation to prevent the
                // bot from getting stuck in a error-loop caused by being in a bad state.
                // ConversationState should be thought of as similar to "cookie-state" in a
                // Web pages.
                return withConversationState.delete(turnContext)
                    .exceptionally(deleteException -> {
                        LoggerFactory.getLogger(AdapterWithErrorHandler.class)
                            .error("ConversationState.delete", deleteException);
                        return null;
                    });
            }
            return CompletableFuture.completedFuture(null);
        });
});
