Spring MVC 将战争部署到 tomcat 8.5

Question

我使用 spring mvc 将我的应用程序部署到 tomcat 8.5。 当我发布要保存的数据时，我收到以下错误。

白标错误页面
此应用程序没有 /error 的显式映射，因此您将其视为后备。
2020 年 6 月 25 日星期四 23:52:59 UTC 出现意外错误（类型=内部服务器错误，状态=500）。 org.hibernate.event.spi.PostInsertEvent.getId()Ljava/io/Serializable;

这是我的pom.xml 文件

其他一切都很好，但只是将方法保存到存储库问题。

Answer 1

我觉得你们之间有冲突

 <dependency>
     <groupId>org.springframework.boot</groupId>
     <artifactId>spring-boot-starter-data-jpa</artifactId>
 </dependency>

还有一些hibernate pom依赖，很可能是下一个

<dependency>
     <groupId>org.hibernate.orm</groupId>
     <artifactId>hibernate-core</artifactId>
     <version>6.0.0.Alpha5</version>
</dependency>
