从 Spring Boot 2.4.3 迁移到 Spring Boot 3.2.2（通过使用 Java 17.0.2）时，我遇到了以下 Spring Data JPA 和 Hibernate 问题：

致以诚挚的问候，

在我看来，好像我已经找到了问题并且可以解决它。这可能是由于使用了 Jakarta Persistence-API 版本 3.2.0-M1。
在我的Maven pom.xml中将Jakarta Persistence-API版本从3.2.0-M1更改为3.1.0后（根据Spring Boot迁移指南，v3.1.0是支持的默认版本）从 Spring Boot 3.2.x 开始，之前抛出的有关 Spring Data JPA/Hibernate/Jakarta 不兼容的异常不再发生:)
虽然 jakarta.persistence-api 依赖项在我的 pom.xml 中被注释掉，但 jakarta-persistence.version 在我的 pom.xml 中设置为属性，显然覆盖了 spring- 中相同属性的值boot-starter-parent pom，它隐式地将适当的 jakarta.persistence-api 依赖项添加到构建中。
摘自我当前的 Maven pom.xml：
