构建 Spring 引导的冲突问题

Question

我在构建 spring 引导应用程序时遇到问题。我们需要使用 Maven 构建具有 'lib/bin/conf' 结构的项目。我用另一个项目做的，没有问题。但是现在，发生了冲突，建议采取措施。

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？公司提供的部分库已被删除。这是我的 pom 文件。

Answer 1

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'看spring-2.5.5是如何被包含的，排除再试

Answer 2

Spring2.5.5has been obsolete for 12 years；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；依赖管理是 Maven 的大部分功能 for.

我在您的 POM 中看不到任何可以引入 Spring 2.5.5 的内容。是否有可能与您的项目相关的其他内容打错了字并打算包含 Spring Boot 2.5.5？在任何情况下，确定这是从哪里来的 (mvn dependency:tree) 并修复它。
