Int*_*ive 3 spring hibernate jpa spring-boot
我按照https://youtu.be/jj2rNQuLEbg上的“Spring Boot 初学者教程 #1”进行操作，最终使用Maven基于原始的配置 ( )完美地运行了整个微服务pom.xml。所有内容都在 Eclipse 上构建和运行IntelliJ IDEA 2023.1.1，而不是教程中的 Eclipse。
然而，当我尝试将相同的源代码移植到 build.gradle` Gradle-based configuration (）时，它构建得非常完美，但在运行时它会抛出以下异常：

您在 maven -> gradle 迁移期间升级了 hibernate 依赖项吗？
该类MySQL5InnoDBDialect在 6.x 版本中已从 hibernate-core 中删除。可以使用与 pom.xml 中完全相同的版本，也可以简单地使用该类org.hibernate.dialect.MySQLDialect。
