在一位客戶，我正在研究一個需要審覈的應用程序。這些審計記錄應該可以在網頁中查看，並且我正在修改當前存在的數據以做到這一點。 Maven的編譯代碼沒有錯誤，但調用該網頁顯示的審覈記錄時，我收到下面的異常沒有找到Autowired bean的候選人

我參加了一個外形酷似模塊爲例，建立我的代碼。其他模塊工作正常，所以我必須錯過一些東西... 任何建議是值得歡迎的。
當添加默認構造函數並在其中設置斷點時，我注意到AuditService類的構造函數從不被調用。
請檢查@Service註釋是否爲org.springframework.stereotype.Service – Michal
@Michal：是的，它是。 –
我懷疑這是原因。整個項目中都使用相同的ServletContainer類。 –
