构建 Spring boot 的冲突问题

Question

我在构建 Spring Boot 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。 我用另一个项目做了，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

我怎么解决这个问题？ 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' 查看 spring-2.5.5 是如何包含的，排除它并重试

Answer 2

Spring 2.5.5 已经过时 12 年； 你没有理由拥有它。 此外，在 Maven 中拥有一个lib目录绝对没有任何意义。 依赖管理是 Maven 的主要用途。

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出现错字并打算包括 Spring Boot 2.5.5？ 无论如何，确定这是从哪里来的（ mvn dependency:tree ）并修复它。
