我正在春季做一个简单的项目。现在,我正在从教程中重写代码,但是未创建H2表。我的代码中唯一的区别是@Entity被标记为已弃用,而在本教程中则没有。有人可以帮我吗?谢谢你。
这是我的.pom文件中的代码:

spring.jpa.hibernate.ddl-auto=create-drop
spring.jpa.show-sql=true
和我的模型班之一:
@Entity
public class Category {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
private String name;
...
答案 0 :(得分:0)
如果@Entity注释被标记为已弃用,则可能意味着您正在导入Hibernate的注释,而不是JavaEE javax.persistence.Entity
。您可以在Hibernate自己的test suite或几乎任何其他tutorial中找到一些示例。甚至官方Hibernate guide都说要使用javax.persistence.*
注释。也许这可以解决您的问题。
*想保留此评论,但没有50个代表的要求。
