错误描述

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

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:1319)

The following method did not exist:

    'java.lang.String javax.servlet.ServletContext.getVirtualServerName()'

The calling method's class, org.apache.catalina.authenticator.AuthenticatorBase, was loaded from the following location:

    jar:file:/Users/springforest/.m2/repository/org/apache/tomcat/embed/tomcat-embed-core/9.0.68/tomcat-embed-core-9.0.68.jar!/org/apache/catalina/authenticator/AuthenticatorBase.class

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

    jar:file:/Users/springforest/.m2/repository/javax/servlet/servlet-api/2.5/servlet-api-2.5.jar!/javax/servlet/ServletContext.class
    jar:file:/Users/springforest/.m2/repository/org/apache/tomcat/embed/tomcat-embed-core/9.0.68/tomcat-embed-core-9.0.68.jar!/javax/servlet/ServletContext.class

The called method's class hierarchy was loaded from the following locations:

    javax.servlet.ServletContext: file:/Users/springforest/.m2/repository/javax/servlet/servlet-api/2.5/servlet-api-2.5.jar


Action:

Correct the classpath of your application so that it contains compatible versions of the classes org.apache.catalina.authenticator.AuthenticatorBase and javax.servlet.ServletContext

错误原因

在tomcat-embed-core.jar和servlet-api-2.5.jar里面都有javax.servlet.ServletContext, 而这个类在eureka中使用默认用了servlet-api-2.5.jar。所以排除即可

解决方法

在Eureka的依赖中添加排除项
