BeanCreationException和NoClassDefFoundError：我在這裏丟失了什麼？

我檢查類路徑和我有它設置正確，那麼爲什麼不FileUploadController工作？有什麼建議麼？

更新

只是想在這個問題上增加一個更新 - 最後，我是能夠得到文件上傳工作，但我不得不重新開始，我創建FileUploadController再次，做了所有再次佈線，現在它似乎工作正常。不過，我無法弄清楚早期錯誤的問題。

我沒有看到標記（MVC：註解驅動）在你的Spring上下文文件。請將其添加到應解決問題的上下文文件中。

''我有這個標籤，我認爲它就夠了？糾正我，如果我的理解是錯誤的 – Rachel

我認爲mvc：註解驅動是什麼標識@controller標記。 –

看這裏http://stackoverflow.com/questions/3977973/whats-the-difference-between-mvcannotation-driven-and-contextannotation-c –

如果CLASSPATH意味着環境變量給你，那是你的問題。

你需要在你的應用程序的WEB-INF/lib目錄或爲你的應用服務器的/ lib目錄下所有的依賴JAR文件。（最好的WEB-INF/lib目錄下。）

刪除CLASSPATH環境變量;這不是必要的，在這種情況下，沒有做任何事情，只是誤導了你。

我也從以前的意見，其他問題理解CLASSPATH是不是enviornment可變的，相信我，我知道，但這裏的問題是，我確實有過FileUploadController所有必要的罐子，更不是裝在任何廣口瓶中的各個控制器而且我確實看到它是目標文件夾中的.class – Rachel

我已經更新了關於'.classpath'文件的詳細問題，其中列出了所有依賴文件夾 – Rachel

您還會在這些場景中尋找哪些內容？ – Rachel

BeanCreationException和NoClassDefFoundError：我在這裏丟失了什麼？
