Field 'id' doesn't have a default value because of generated value-CodePudding

My entities

FoodItem.java

@AllArgsConstructor
@NoArgsConstructor
@Builder
@Entity
@Setter
@Getter
@Table(name = "food_items", schema = "restaurant-service")
@FieldDefaults(level = AccessLevel.PRIVATE)
public class FoodItem {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    Long id;

    String name;

    BigDecimal price;

    Long restaurant_id;

}

Restaurant.java

@AllArgsConstructor
@NoArgsConstructor
@Builder
@Entity
@Setter
@Getter
@Table(name = "restaurant", schema = "restaurant-service")
@FieldDefaults(level = AccessLevel.PRIVATE)
public class Restaurant {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    Long id;

    String name;

    String address;

    BigDecimal priceForDelivery;

    @OneToMany
    @JoinColumn(name = "restaurant_id")
    List<FoodItem> menu;
}

Controller

 @PostMapping(value = "/restaurant/{restaurantId}/item")
    public void createRestaurant(@PathVariable(value = "restaurantId")Long restaurantId,
                                 @RequestBody FoodItem foodItemRequest) {
        repository.findById(id).map(restaurant -> restaurant.getMenu().add(foodItemRequest));
    FoodItem foodItem = FoodItem.builder()
            .name(foodItemRequest.getName())
            .price(foodItemRequest.getPrice())
            .restaurant_id(id)
            .build();
    foodItemRepository.save(foodItem);
    }

I just need to save food item in controller without posting an ID, I need that id will be generated without me

I tried to change strategy to the AUTO but it still didn't work

CodePudding user response：

If your MySQL table must support IDENTITY primary key generation strategy you must create the primary key with auto_increment.

Example:

CREATE TABLE animals (
     id MEDIUMINT NOT NULL AUTO_INCREMENT,
     name CHAR(30) NOT NULL,
     PRIMARY KEY (id)
);

IDENTITY means that the database will take care of the generation of the primary key.

CodePudding user response：

Have you tried setting default id value as null? Usually what I do in Kotlin.
