引起:org.hibernate.HibernateException:未设置'hibernate.dialect'时,对DialectResolutionInfo的访问不能为null.

Question

即使在设置了hibernate.dialect属性后,我也会遇到异常.我使用的是带有spring boot 1.4.2的hibernate 5.0.11和带有5.7的mysql版本

application.properties is like this

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

的pom.xml

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

这是什么问题？
