在Tomcat上部署時，Spring引導@Autowired Annotation不起作用

Question

@Outowired在將我的spring引導應用程序打包爲tomcat的war時部署爲null，但使用spring引導的嵌入式tomcat時可以正常工作。 請幫忙嗎？

在我的應用程序下面的pom.xml文件做工精細，並在展開時單機的Tomcat also.Do檢查，如果你已經取得範圍，因爲提供的嵌入式服務器在你的pom.xml文件中。

您可以粘貼您的pom.xml文件。

因爲我沒有你的孩子的項目，我已經合併雙方pom.xml文件內容到一個和它運行得很好，我local.Please你pom.xml文件進行比較。
