我在Weblogic 12c上部署EAR包,並獲取ClassNotFoundException
。但是,似乎該項目沒有任何關於缺失類的提及(我已經搜索了類名,結果爲零)。我知道這個異常在丟失類被試圖通過反射實例化時拋出。我懷疑一些圖書館可能依賴於這個班級。ClassNotFoundException,如何找到丟失類的地方
如何找出哪些配置或用戶代碼導致類的實例化?服務器日誌沒有提供足夠的詳細信息,但這裏是

這是發生在您的開發環境中還是僅在生產模式?你可以在IDE中調試你的應用程序嗎?如果是這樣,你用什麼IDE? –
好吧,它發生在開發環境中,我從庫中刪除了明顯未使用的類。我必須知道這個班級需要什麼,即使沒有參考。也許類名是動態構建的,所以我不能搜索它,但是我怎麼知道哪個類試圖加載這個類?爲什麼我無法從服務器日誌中看到它? –
