springboot项目启动报错：

Description:

An attempt was made to call a method that does not exist. The attempt was made from the following location:

    org.apache.catalina.authenticator.AuthenticatorBase.startInternal(AuthenticatorBase.java:1355)

The following method did not exist:

    javax.servlet.ServletContext.getVirtualServerName()Ljava/lang/String;

The method's class, javax.servlet.ServletContext, is available from the following locations:

    jar:file:/F:/Program%20Files%20(x86)/Maven%20%20Registory/javax/servlet/servlet-api/2.5/servlet-api-2.5.jar!/javax/servlet/ServletContext.class
    jar:file:/F:/Program%20Files%20(x86)/Maven%20%20Registory/org/apache/tomcat/embed/tomcat-embed-core/9.0.41/tomcat-embed-core-9.0.41.jar!/javax/servlet/ServletContext.class

查阅资料说的是：Maven依赖冲突jar包冲突类冲突 ，

具体原因:多个jar包 中包含同一个类

解决思路:将The method’s class, javax.servlet.ServletContext, is available from the following locations: 提示的jar删除或者改为test

然后就ok了
