我在獨立的Java應用程序中使用Spring IoC。當應用程序啓動時,它會創建一個包含啓動信息的日誌。有些信息我不明白,請幫助我理解它們並解釋如何修復它們,如果它們必須修復?另外我很好奇:由於這些消息,我的應用程序穩定性是否存在危險?這些Spring調試消息是什麼意思?
嚇跑我的消息從單詞「Unable」開始。目前該應用程序工作得很好。

嗨菲爾,謝謝你的回覆。其實我自己明白(如果我設法寫應用程序:-)。我需要更多細節。那些無法實際意義的東西。無法 - 對於計算金錢的應用程序而言是個壞詞......我想。但您的回覆讓我放鬆了一下... – Worker 2011-06-02 12:30:37
@MinimeDJ在這種情況下,我建議您閱讀MessageSource,ApplicationEventMulticaster和LifecycleProcessor的Javadocs。 Spring的全部意義在於你可以自定義它的一些部分。所有日誌輸出告訴你,它使用默認功能,而不是自定義功能。 – 2011-06-02 12:32:23
@MinimeDJ:調試級日誌消息是您不需要擔心的事情。設置你的根日誌記錄級別警告,然後爲你想要更多細節的特定包添加更低的日誌記錄級別,比如你的應用程序代碼。 – 2011-06-02 12:34:32
