Java Spring教程：创建名为'；实体管理工厂&x27；在类路径资源中定义

我尝试在springboot上遵循这个官方的spring.io，并使用JPA访问数据。
这是关于使用h2数据库执行一些“简单”操作。 关于这个话题还有其他一些问题，但他们的解决方案都不适合我。
如果这很重要，我将使用Java11SDK

我甚至从教程中下载了.zip文件，但无论我做什么，最终都会出现以下错误消息：

添加此依赖项：

 compile group: 'org.javassist', name: 'javassist', version: '3.23.1-GA'

javassist在Java 11上有问题。

你让我很开心。“我怎么会知道呢？”马丁检查：

 compile group: 'org.javassist', name: 'javassist', version: '3.23.1-GA'
