org.springframework.beans.factory.UnsatisfiedDependencyException，java.lang.Error：未解決的編譯問題

Question

任何人都可以告訴我，爲什麼會發生此錯誤？ 其實我不明白從哪裏開始解決它。

導致大量的異常級聯一路上漲的基礎例外是

java.lang.Error: Unresolved compilation problems: 

這意味着帽子你的java文件中的一個有無效語法和編譯器錯誤消息，並未能成功編譯。 YOu應該重建整個項目並檢查編譯錯誤的所有源代碼。錯誤類可能是

com.greytip.wps.service.impl.PasswordManagerImpl
