我使用springboot2.1.3去集成dubbo 2.6.5的时候出现这样的一个问题，不知道是什么意思

Description:An attempt was made to call the method org.apache.catalina.connector.Connector.setProtocol(Ljava/lang/String;)V but it does not exist. Its class, org.apache.catalina.connector.Connector, is available from the following locations:

    jar:file:/F:/Mavenrepositories/org/apache/tomcat/embed/tomcat-embed-core/9.0.13/tomcat-embed-core-9.0.13.jar!/org/apache/catalina/connector/Connector.class

It was loaded from the following location:

    file:/F:/Mavenrepositories/org/apache/tomcat/embed/tomcat-embed-core/9.0.13/tomcat-embed-core-9.0.13.jar

Action:

Correct the classpath of your application so that it contains a single, compatible version of org.apache.catalina.connector.Connector

我看了我本地仓库中是有这个jar的，而且我的项目中也依赖了这个jar,且只有一个依赖
