Question

我目前正在从事Spring动态Web项目。在Tomcat启动时，出现以下错误：

SEVERE: StandardWrapper.Throwable
java.lang.NoSuchMethodError: org.springframework.core.io.ResourceEditor.<init> 
(Lorg/springframework/core/io/ResourceLoader;)V

我已经查看了有关此问题的其他几个问题，建议的问题是从属问题。我去了，将springframework.core的版本更改为以前的版本，但这没有任何改变。

如何解决此问题？将来如何准确诊断此类问题？

您的依赖项一团糟。我看到了Spring Boot的依赖关系。您是否正在尝试创建Spring Boot项目？如果是这样，请转到https://start.spring.io。对于Spring来说，最重要的一点是确保所有基本Spring库都具有相同的版本。为了帮助您解决Maven BOM机制的存在（在Spring Boot中使用了类似的技术）：https://www.baeldung.com/spring-maven-bom
