Description:

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

    org.springframework.boot.web.embedded.tomcat.TomcatServletWebServerFactory.getWebServer(TomcatServletWebServerFactory.java:175)

The following method did not exist:

    org.apache.tomcat.util.modeler.Registry.disableRegistry()V
    
    
     jar:file:/C:/Users/moto/.m2/repository/org/apache/tomcat/embed/tomcat-embed-core/8.5.35/tomcat-embed-core-8.5.35.jar!/org/apache/tomcat/util/modeler/Registry.class

The class hierarchy was loaded from the following locations:

    org.apache.tomcat.util.modeler.Registry: file:/C:/Users/moto/.m2/repository/org/apache/tomcat/embed/tomcat-embed-core/8.5.35/tomcat-embed-core-8.5.35.jar


Action:

Correct the classpath of your application so that it contains a single, compatible version of org.apache.tomcat.util.modeler.Registry

推荐答案

当你使用 spring-boot-stater-parent 时，你可以使用 tomcat.version 属性来控制Tomcat的版本.您已经在 pom.xml 文件中完成了此操作:

When you're using spring-boot-stater-parent as you are, you can use a tomcat.version property to control the version of Tomcat. You've already done this in your pom.xml file:

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
    <java.version>1.8</java.version>
    <tomcat.version>8.5.32</tomcat.version>
</properties>

简而言之，您已经在更改 Spring Boot 使用的 Tomcat 版本.

In short, you are already changing the version of Tomcat that Spring Boot uses.

默认情况下，Spring Boot 2.3.1 使用 Tomcat 9.0.x.如果您从 pom 文件中删除 8.5.32，则应使用 Tomcat 9.0.x，然后您的应用程序应该能够启动.如果要自定义此版本，则应保留 tomcat.version 属性，但使用与 Spring Boot 兼容的版本.建议使用最新的 Tomcat 9.0.x 版本.最近的 8.5.x 版本也可能适用.

By default, Spring Boot 2.3.1 uses Tomcat 9.0.x. If you remove <tomcat.version>8.5.32</tomcat.version> from your pom file, Tomcat 9.0.x should be used and your application should then be able to start. If you want to customise this version then you should keep the tomcat.version property but use a version with which Spring Boot is compatible. The latest Tomcat 9.0.x release is recommended. Recent 8.5.x releases may also work.
