Caused by: java.sql.SQLSyntaxErrorException: Table 'sell.hibernate_sequence' doesn't exist

domain:　　　　

@Entity
public class ProductCategory {
   @Id
   @GeneratedValue
   private Integer categoryId;
   private String categoryName;
   private Integer categoryType;
    setter... 
    getter...

Repository:

public interface ProductCategoryRepository extends JpaRepository<ProductCategory,Integer> {

}

测试代码：

@Test
    public void saveTest(){
        ProductCategory productCategory = new ProductCategory();
        productCategory.setCategoryName("测试b");
        productCategory.setCategoryType(3);
        repository.save(productCategory);
    }

报错：Caused by: java.sql.SQLSyntaxErrorException: Table ‘sell.hibernate_sequence‘ doesn‘t exist

解决：在domain实体类指明主键生成策略，保持数据库一致

@Entity
public class ProductCategory {
   @Id
   @GeneratedValue(strategy = GenerationType.IDENTITY)
   private Integer categoryId;
   private String categoryName;
   private Integer categoryType;

JPA四种生成策略了解下。

疑点：原文使用@GeneratedValue注解，即@GeneratedValue(strategy = GenerationType.AUTO)，不是应该根据数据库支持的主键生成策略自动选择合适的吗，数据库中使用了auto_increment，为什么这边没有支持而报错?
