我在将项目作为spring boot应用程序运行时遇到这个错误,我猜解决方案可能不会太复杂:
错误日志:

说明:
试图调用不存在的方法。尝试从以下位置进行:
org.apache.catalina.startup.Tomcat.<clinit>(Tomcat.java:1303)
以下方法不存在:
'boolean org.apache.tomcat.util.compat.JreCompat.isGraalAvailable()'
该方法的类org.apache.tomcat.util.compat.jrecompat可从以下位置获得:
jar:file:/C:/Users/xxxx/.m2/repository/org/apache/tomcat/tomcat-util/8.5.30/tomcat-util-8.5.30.jar!/org/apache/tomcat/util/compat/JreCompat.class
jar:file:/C:/Users/xxxx/.m2/repository/org/apache/tomcat/embed/tomcat-embed-core/9.0.43/tomcat-embed-core-9.0.43.jar!/org/apache/tomcat/util/compat/JreCompat.class
已从以下位置加载类层次结构:
org.apache.tomcat.util.compat.JreCompat: file:/C:/Users/xxxx/.m2/repository/org/apache/tomcat/tomcat-util/8.5.30/tomcat-util-8.5.30.jar
行动:
请更正应用程序的类路径,使其包含org.apache.tomcat.util.compat.jrecompat的单个兼容版本

我知道,这还没有做很多,但我想运行它和开放http://localhost:8080并查看结果。
我试过查看其他线程中描述的buildpath库,如:disableregistry()不存在(org.apache.tomcat.util.modeler.registry),但我不想太多地处理它,因为我是新手,任何帮助都将不胜感激,谢谢!

你把两个不兼容的版本
tomcat-util
在您的依赖项中:版本9.0.43包含在
tomcat-embed-core
,它是的传递依赖项spring-boot-starter-web
,版本8.5.30是
tomcat-jasper
,这是您单独添加的。你应该使用
embed-tomcat-jasper
而是9.0.43版。maven试图尽可能地消除版本冲突,但它不知道这一点tomcat-jasper
以及embed-tomcat-jasper
都是一样的。
