问题描述
我直接在Spring单元测试中使用 HibernateJpaAutoConfiguration 。虽然配置了Hibernate和 EntityManager ，但没有实体被扫描。

解决方案62.4 Spring配置中单独的@Entity定义
Spring Boot试图猜测您的@Entity定义的位置基于它找到的@EnableAutoConfiguration。为了获得更多控制权，您可以使用@EntityScan批注，例如
@Configuration @EnableAutoConfiguration @EntityScan（basePackageClasses = City.class） public class Application { // ... }
I'm using HibernateJpaAutoConfiguration directly in a Spring unit test. While Hibernate and EntityManager is configured, no entities are scanned.

解决方案From the Spring Boot reference...
62.4 Separate @Entity definitions from Spring configuration
Spring Boot tries to guess the location of your @Entity definitions, based on the @EnableAutoConfiguration it finds. To get more control, you can use the @EntityScan annotation, e.g.
@Configuration @EnableAutoConfiguration @EntityScan(basePackageClasses=City.class) public class Application { //... }
