java.lang.IllegalArgumentException：不是托管類型：classTestEntity

Question

我正在嘗試使用Spring JPA從數據庫的兩個表中獲取數據：

並有例外：

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

產品實體為：

@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;
}

儲存庫為

public interface CaKeyRepository extends JpaRepository<Product, Integer> {

}

嘗試加載findAll（）;

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

我也使用WildFly 12應用程序服務器。

看來您的實體沒有被休眠掃描。

如果您通過persistence.xml配置了JPA / Hibernate： <class>com.entity.Product</class>

如果通過Spring-ORM，則在您的LocalContainerEntityManagerFactoryBean中，在packagesToScan方法中設置包。
