Question

Spring日志显示该表在数据库中被创建了两次，尽管数据库只显示了一组表。

这只发生在我运行mvn verify以运行集成测试

时

SpringBoot 1.5.6版

这是日志

application.properties

spring.datasource.url = jdbc:hsqldb:mem:manudcamera_api_sandbox
spring.datasource.username = sa
spring.datasource.password =
spring.datasource.driver-class-name = org.hsqldb.jdbcDriver
spring.jpa.hibernate.ddl-auto = update
spring.jpa.show-sql = false

示例实体类，省略了setter / getter。 AbstractEntity Class

@MappedSuperclass
@EntityListeners(AuditingEntityListener.class)
public abstract class AbstractEntity implements Serializable {

    @Id
    @GeneratedValue
    private Long id;

    @CreatedDate
    private Date createdDate;

    @LastModifiedDate
    private Date lastModifiedDate;

    @Override
    public abstract int hashCode();

    @Override
    public abstract boolean equals(Object obj);
}

相册

@Entity
public class Album extends AbstractEntity {

    @Column(nullable = false)
    private String uuid;

    @Column(nullable = false)
    private String name;

    @OneToMany(cascade = {CascadeType.PERSIST, CascadeType.REMOVE, CascadeType.REFRESH}, orphanRemoval = true)
    private Set<Image> imageSet = new HashSet<>(0);

}

Spring Hibernate同样创建两次表
