在 class 路径资源中创建名称为 'entityManagerFactory' 的 bean 时出错 - 来自 SO 的解决方案不起作用
Error creating bean with name 'entityManagerFactory' defined in class path resource - solutions from SO does not work
我从1.5.9 SpringBoot迁移到2.1.1出现了这个错误。我在这个网站上添加了来自不同问题的新依赖，但它没有改变任何东西。
新的依赖项是：
- javax.xml.bind
这是堆栈跟踪（那里有完整的堆栈跟踪，我无法将其粘贴在这里，因为它太长了：https://pastebin.com/i8fMn6s8）；

你能详细回答一下我该怎么办吗？
此 class 仅在验证 API 2.0 后可用：javax.validation.ClockProvider
考虑升级这个依赖的版本：
<dependency>
<groupId>javax.validation</groupId>
<artifactId>validation-api</artifactId>
<version>1.1.0.Final</version>
</dependency>
这是具有可用版本的 Maven 存储库："javax.validation" for Maven
你加入这个有什么原因吗？
<dependency>
<groupId>javax.validation</groupId>
<artifactId>validation-api</artifactId>
<version>1.1.0.Final</version>
</dependency>
你的pom.xml排除validation-api后可以正常工作，如下：

你能详细回答一下我该怎么办吗？
此 class 仅在验证 API 2.0 后可用：javax.validation.ClockProvider
考虑升级这个依赖的版本：
<dependency>
<groupId>javax.validation</groupId>
<artifactId>validation-api</artifactId>
<version>1.1.0.Final</version>
</dependency>
这是具有可用版本的 Maven 存储库："javax.validation" for Maven
你加入这个有什么原因吗？
<dependency>
<groupId>javax.validation</groupId>
<artifactId>validation-api</artifactId>
<version>1.1.0.Final</version>
</dependency>
你的pom.xml排除validation-api后可以正常工作，如下：
