Springboot Maven：更正应用程序的类路径，使其包含类的兼容版本

Question

我在运行Springboot Maven应用程序时遇到问题。这个问题始于一个缺失的依赖关系，这让我无法解决另一个问题，我尝试了来自整个网络的多个建议，但都无济于事。我确实移除了。m2文件夹并重新构建，但同样的错误再次出现。

我控制台中的错误：

***************************
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.orm.jpa.support.PersistenceAnnotationBeanPostProcessor$PersistenceElement.<init>(PersistenceAnnotationBeanPostProcessor.java:650)

The following method did not exist:

    'javax.persistence.SynchronizationType javax.persistence.PersistenceContext.synchronization()'

The calling method's class, org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor$PersistenceElement, was loaded from the following location:

    jar:file:/C:/Users/Kevin/.m2/repository/org/springframework/spring-orm/5.3.19/spring-orm-5.3.19.jar!/org/springframework/orm/jpa/support/PersistenceAnnotationBeanPostProcessor$PersistenceElement.class

The called method's class, javax.persistence.PersistenceContext, is available from the following locations:

    jar:file:/D:/School%20Novi/Eindopdracht/BackEnd/demodrop-be/lib/javax.persistence.jar!/javax/persistence/PersistenceContext.class
    jar:file:/C:/Users/Kevin/.m2/repository/jakarta/persistence/jakarta.persistence-api/2.2.3/jakarta.persistence-api-2.2.3.jar!/javax/persistence/PersistenceContext.class
    jar:file:/C:/Users/Kevin/.m2/repository/javax/persistence/javax.persistence-api/2.2/javax.persistence-api-2.2.jar!/javax/persistence/PersistenceContext.class

The called method's class hierarchy was loaded from the following locations:

    javax.persistence.PersistenceContext: file:/D:/School%20Novi/Eindopdracht/BackEnd/demodrop-be/lib/javax.persistence.jar


Action:

Correct the classpath of your application so that it contains compatible versions of the classes org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor$PersistenceElement and javax.persistence.PersistenceContext

谢谢大家，删除提到的依赖项解决了这个问题。这一切都始于一个错误，说明javax.persistence未加载，这是由依赖项的不当选择事后造成的。我大约5个月前才开始学习前端和后端开发的在线课程，所以它仍然有点令人生畏。
