NVARCHAR不支持类型

application.properties设置方言不生效

`public static final int NVARCHAR = -9;`

为什么在设置此属性时可以在Internet上设置它

#spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.SQLServer2008Dialect
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.SQLServerDialect

如何配置不支持数据库类型的问题

向上帝求助，谢谢

org.springframework.boot-spring-boot-starter-parent 1.5.4.RELEASE互联网是在1.4.0.RELEASE版本中设置的，但我使用的版本不同，因为数据库类型不同？在线是mysql，我使用sql server是示例hibernate属性，用于spring boot您还可以扩展

SQLServerDialante

，如图所示，谢谢您，这已经尝试过了，没有错误，但遇到了一个新问题，替换为mybatisorg.springframework.boot spring boot starter parent 1.5.4.RELEASE Internet是在版本1.4.0.RELEASE中设置的，但我不使用相同的版本，因为数据库类型不同？在线是mysql，我使用sql server是示例hibernate属性，用于spring boot，您还可以扩展

，如图所示，谢谢您，这已经尝试过了，没有错误，但遇到了一个新问题，被mybatis取代
