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

员工类别

        job_role + ", id="+ id + "]";
    }   

}

employeecontroller类

package com.simpleSpringHTTPService.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class EmployeeController {

    @RequestMapping("/")
    public String home() {

        return "home.jsp";
    }
}

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。
