編輯pom.xml後，Spring啓動應用程序無法啓動

當我從SVN存儲庫下載我們的項目並啓動項目時，它工作正常，一切正常。但是，每當我添加一些依賴到pom.xml並啓動項目，它給了我這個例外。編輯pom.xml後，Spring啓動應用程序無法啓動

誰能告訴我是什麼導致這個問題？

不要添加版本，讓父pom負責添加正確的版本。 – helospark

我沒有添加版本，但它沒有解決我的問題 – paxie

從Tomcat啓動刪除<scope>provided</scope>。

您正在製作一個可執行的jar文件，因此嵌入式Tomcat將提供與servlet相關的類而不是servlet容器。
因此需要編譯範圍，所以Tomcat將成爲您構建的jar文件的一部分。

它的工作表示感謝。請你提供更深的解釋，爲什麼它解決了我的問題嗎？ – paxie

@paxie提供的範圍意味着，它將在編譯期間可見，但它不是構建的jar文件的一部分，將由其他人提供。例如，在普通的Spring應用程序中，servlet-api包含在提供的範圍中，因爲在這種情況下，獨立的Tomcat提供了這個實現。但在Spring Boot應用程序中，嵌入式Tomcat包含實現，因此它必須是jar文件的一部分（因此需要編譯範圍）。 'ClassNotFoundException'意味着它在運行時沒有找到類（因爲它不包含在jar中）。 – helospark
