hibernate - 由 : org. hibernate.HibernateException : Access to DialectResolutionInfo cannot be null when 'hibernate.dialect' not set. 引起

Question

即使设置 hibernate.dialect 属性后，我也会遇到异常。我使用的是 hibernate 5.0.11 和 spring boot 1.4.2，mysql 版本为 5.7

application.properties is like this

# Hibernate
hibernate.dialect=org.hibernate.dialect.MySQL5Dialect
hibernate.show_sql=true
hibernate.hbm2ddl.auto=validate

pom.xml

        <groupId>org.springframework.boot</groupId>

这里有什么问题吗？

Answer 1

当我遇到该错误时，将以下行添加到 properties 文件中可以解决此问题。

spring.jpa.database=mysql
