java.lang.IllegalArgumentException: Not an managed type: classTestEntity

Question

I'm trying to get data using Spring JPA from two table in database:

And have the exception:

nested exception is java.lang.IllegalArgumentException: Not an managed type: class com.entity.Product

Product entity is:

@Entity
@Table(name = "PRODUCT")
@Getter
@Setter
public class Product {
    @Id
    @Column(name = "id", unique = true, nullable = false)
    private int id;

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

    @OneToMany(mappedBy = "productService", fetch = FetchType.EAGER)
    private List<ProductService> productService;

    @ManyToOne(targetEntity = ProductStatus.class, optional = false)
    @JoinColumn(name = "PRODUCT_STATUS_ID")
    private ProductStatus status;
}

Repository is

public interface CaKeyRepository extends JpaRepository<Product, Integer> {

}

Trying to load with findAll();

public HashMap<String, Key> loadProduct() throws Exception {
    List<Product> products = caKeyRepository.findAll();

Also I use the WildFly 12 application server.

Look like your entity is not scanned by hibernate.

If you configured JPA/Hibernate through persistence.xml: <class>com.entity.Product</class>

if through Spring-ORM then in your LocalContainerEntityManagerFactoryBean set the package in the packagesToScan method.
