Springboot啟動報錯:child container failed during start

Caused by: java.lang.NoSuchMethodError: javax.servlet.ServletContext.getVirtualServerName()Ljava/lang/String;

引入了一個hsf pom檔案後後，翻到異常堆棧最下面發現是：ServletContext沒有getVirtualServerName方法，原因是pom沖突，解決方案：在hsf裡面先排除就得servlet-api，在引入最新的：

A child container failed during start是結果，不是原因。

完整報錯資訊：
