如何解决 SpringBoot 错误：从 Java11 迁移到 Java 23 后出现“组件需要一个名为‘entityManagerFactory’的 bean，但无法找到”

Question

我正在致力于将一个大型现有项目从 Java 11/SpringBoot 2.4.11 迁移到 Java 21/SpringBoot 3.3.4。 我已遵循迁移指南并修复了已弃用的方法错误，现在运行

gradle clean build

可以成功执行。

但是，当我尝试启动应用程序时，我看到以下异常

***************************
APPLICATION FAILED TO START
***************************

Description:

A component required a bean named 'entityManagerFactory' that could not be found.


Action:

Consider defining a bean named 'entityManagerFactory' in your configuration.

16:24:24.624 [main] ERROR com.xxxx.xxx.xxx.Application main application exited
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'jpaSharedEM_entityManagerFactory': Cannot resolve reference to bean 'entityManagerFactory' while setting constructor argument

我已经研究过这个问题，这似乎是由不兼容的 Springboot 依赖项引起的，但我无法确定哪些依赖项是问题所在，因为我所有的 spring 依赖项似乎都匹配 3.3.4。

我的build.gradle文件：

    buildDir = 'target'

不是您问题的完整解决方案，但我在使用 Spring 3.3.5 时遇到了同样的问题。即使只是遵循 Spring 指南也无法在示例应用程序上工作。如果你降级到 3.3.3 就可以了。

但这并不能解释 Spring Boot 3.3.4 及以后的不兼容版本是什么
