spring boot报错org.apache.catalina.core.ContainerBase : A child container failed during start

刚开始学spring boot遇到的问题

原因

其中有一句

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

解决

• 最开始按照网上说的，是因为项目servlet-api冲突，删掉重复的保留默认的，并没有解决。

• 之后请教别人发现可能是加载了版本低的jar包，jdk版本低，我的解决办法是重新安装jdk1.8.0最新版1.8.0_241，随后成功启动。

• 网上还有一种解决方法是，删掉本地的javaee.jar包。

• 也可以通过新建一个Spring Initializr项目，通过错误日志来查看详细错误信息。

感想：道路千万条，仔细看日志第一条。
