导入达梦数据库对hibernate的方言包

<dependency>
            <groupId>com.dameng</groupId>
            <artifactId>DmDialect-for-hibernate5.6</artifactId>
            <version>8.1.2.192</version>
        </dependency>

配置文件中添加方言配置和主键生成策略配置

spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.DmDialect
spring.jpa.properties.hibernate.id.new_generator_mappings=false

兼容Oracle

兼容Mysql
