Springboot启动报错:child container failed during start

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

引入了一个hsf pom文件后后，翻到异常堆栈最下面发现是：ServletContext没有getVirtualServerName方法，原因是pom冲突，解决方案：在hsf里面先排除就得servlet-api，在引入最新的：

A child container failed during start是结果，不是原因。

<!--引入新的-->
