参考:springboot启动报错The method‘s class, javax.servlet.ServletContext, is available from the following loca_waper97的博客-CSDN博客

刚开始的时候是查看springboot启动报错The method‘s class, javax.servlet.ServletContext, is available from the following loca_waper97的博客-CSDN博客 博客去弄的,当时好了,后来刷新下maven发现又不行了,最后解决办法就是排除依赖

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

后续处理

后面发现又不行了, 解决办法是

排除掉其中一个maven依赖

然后点击下面的两个箭头的东西,重新刷一下maven

重启项目, 发现好了
