錯誤原因： 根據(jù)實體創(chuàng)建表失敗

解決：
方式一：
@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class, JpaRepositoriesAutoConfiguration.class, HibernateJpaAutoConfiguration.class})

方式二（建議使用）：

spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl
