APPLICATION FAILED TO START
***************************

Description:

An attempt was made to call the method javax.servlet.ServletContext.getVirtualServerName()Ljava/lang/String; but it does not exist. Its class, javax.servlet.ServletContext, is available from the following locations:

    jar:file:/C:/Users/Administrator/.m2/repository/javax/servlet/servlet-api/3.0-alpha-1/servlet-api-3.0-alpha-1.jar!/javax/servlet/ServletContext.class
    jar:file:/C:/Users/Administrator/.m2/repository/org/apache/tomcat/embed/tomcat-embed-core/9.0.16/tomcat-embed-core-9.0.16.jar!/javax/servlet/ServletContext.class

It was loaded from the following location:

    file:/C:/Users/Administrator/.m2/repository/javax/servlet/servlet-api/3.0-alpha-1/servlet-api-3.0-alpha-1.jar

Action:

Correct the classpath of your application so that it contains a single, compatible version of javax.servlet.ServletContext

Disconnected from the target VM, address: '127.0.0.1:56191', transport: 'socket'

Process finished with exit code 1

这问题困挠了很久，在网上找了很多解决方法都不对，项目是新建的一个springboot项目，引入了一个自己的jar就出这个问题，最后仔细看了提示 file:/C:/Users/Administrator/.m2/repository/javax/servlet/servlet-api/3.0-alpha-1/servlet-api-3.0-alpha-1.jar 这一句 感觉还是这个jar冲突的问题。最后在自己jar中将servlet-api-3.0这个jar去掉，重新安装jar问题得到解决。最后感觉出现问题还是要仔细阅读错误提示信息，虽然java的错误输出提示可读性实在太差，可还是得从里面找到答案。
