英文:
nested exception is org.hibernate.HibernateException: Access to DialectResolutionInfo cannot be null when 'hibernate.dialect' not set
问题
我目前正在进行一个基于Spring的网页项目课程，遇到了以下异常情况，但我无法找到解决方法。
org.springframework.beans.factory.BeanCreationException: 在 ServletContext 资源 [/WEB-INF/dispatcher-servlet.xml] 中定义的名为 'entityManagerFactory' 的 bean 创建时出错：调用 init 方法失败；嵌套异常是 org.hibernate.HibernateException: 当未设置 'hibernate.dialect' 时，无法将 DialectResolutionInfo 访问为空
这是完整项目的链接：

如果有人能够对其进行调试并告诉我问题出在哪里，那将非常有帮助。
谢谢。

I am currently working on a web Spring school project, and I ran into this exception and I can't find my way out of it.
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in ServletContext resource [/WEB-INF/dispatcher-servlet.xml]: Invocation of init method failed; nested exception is org.hibernate.HibernateException: Access to DialectResolutionInfo cannot be null when 'hibernate.dialect' not set
here's the link to the full project :

if someone can debug it and tell me where the problem is, that would be very helpful.
My thanks.

你缺少一个应用程序属性，即 spring.jpa.database-platform。您应根据您使用的数据库进行适当设置。例如：spring.jpa.database-platform=org.hibernate.dialect.PostgreSQLDialect
附注：这可能不是您唯一缺少的属性，您应该添加您的 application.properties 文件以查看您可能存在的其他问题。
英文:
You are missing a application property, spring.jpa.database-platform. You should set it accordingly to the database you are using. E.g. spring.jpa.database-platform=org.hibernate.dialect.PostgreSQLDialect
P.S. This might not be the only property you are missing, you should add your application.properties file to see what other problems you might have.
