Hibernate 在Spring Boot中使用Junit测试Hibernet时出现问题

我想测试Spring数据层 我有基本的

@Entity

产品：

@Entity
@Table(name = "products")
@JsonIgnoreProperties({ "hibernateLazyInitializer", "handler" })
public class Product{

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "i_user")
    private int id;

    @Column(name = "user_name")
    private String userName;

我有

ProductRepository

Repository:

public interface ProductRepository extends JpaRepository<Product, Integer> {

}

我有一个错误：

18:53:15.926 [main] DEBUG org.springframework.test.context.junit4.SpringJUnit4ClassRunner - SpringJUnit4ClassRunner constructor called with [class com.ProductTest]

您使用的是哪个Spring启动版本？我使用的是这个版本

2.1.4.RELEASE

是否插入实体实例？是键入@Autowired private ProductRepository ProductRepository而不是private ProductRepository；。我在写文章时犯了错误。我正在使用

ProductRepository

。这不是问题。
