我在构建spring引导应用程序时遇到了问题。我们需要使用maven构建带有'lib/bin/conf'结构的项目。我在另一个项目中也这样做过，没有问题。但是现在，发生了冲突，建议采取行动。

APPLICATION FAILED TO START
***************************
Description:
An attempt was made to call a method that does not exist. The attempt was made from the following location:
org.springframework.beans.factory.support.DefaultSingletonBeanRegistry.<init>(DefaultSingletonBeanRegistry.java:88)
The following method did not exist:
'java.util.Map org.springframework.core.CollectionFactory.createConcurrentMapIfPossible(int)'
The calling method's class, org.springframework.beans.factory.support.DefaultSingletonBeanRegistry, is available from the following locations:
jar:file:/Users/user/.m2/repository/org/springframework/spring/2.5.5/spring-2.5.5.jar!/org/springframework/beans/factory/support/DefaultSingletonBeanRegistry.class
jar:file:/Users/user/.m2/repository/org/springframework/spring-beans/5.3.18/spring-beans-5.3.18.jar!/org/springframework/beans/factory/support/DefaultSingletonBeanRegistry.class
The calling method's class was loaded from the following location:
file:/Users/user/.m2/repository/org/springframework/spring/2.5.5/spring-2.5.5.jar
The called method's class, org.springframework.core.CollectionFactory, is available from the following locations:
jar:file:/Users/user/.m2/repository/org/springframework/spring-core/5.3.18/spring-core-5.3.18.jar!/org/springframework/core/CollectionFactory.class
jar:file:/Users/user/.m2/repository/org/springframework/spring/2.5.5/spring-2.5.5.jar!/org/springframework/core/CollectionFactory.class
The called method's class hierarchy was loaded from the following locations:
org.springframework.core.CollectionFactory: file:/Users/user/.m2/repository/org/springframework/spring-core/5.3.18/spring-core-5.3.18.jar
Action:
Correct the classpath of your application so that it contains compatible versions of the classes org.springframework.beans.factory.support.DefaultSingletonBeanRegistry and org.springframework.core.CollectionFactory
我该如何解决这个问题?该公司提供的一些库已被删除。这是我的文件。

Spring 2.5.5已经过时12年了;你没有理由拥有它。此外，在Maven中使用lib目录绝对没有任何意义;依赖管理在很大程度上是Maven对于的作用。
我在你的POM中看不到任何会在Spring 2.5.5中拉的东西。是否有可能是其他与您的项目相关的东西打错了，并打算包括SpringBoot2.5.5吗?在任何情况下，确定它来自哪里(mvn dependency:tree)并修复它。
DefaultSingletonBeanRegistry和CollectionFactory在spring-2.5.5中是重复的，实际上它们已经包含在spring-beans和spring-core中。
执行'mvn dependency:tree -Dverbose'查看spring-2.5.5是如何包含的，排除它，然后再试一次
