I have two entities Product and Image, the image has a Product foreign key.

When i try to run the code i get the following error

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'mainController': Unsatisfied dependency expressed through field 'imageRepository'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'imageRepository': Invocation of init method failed; nested exception is org.springframework.data.mapping.PropertyReferenceException: No property product found for type Image!

Product entity

@Entity
@Table(name = "product")
public class Product {
    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    private Integer id;

    private String name;

    private String description;

    private Integer parent_product_id;

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getDescription() {
        return description;
    }

    public void setDescription(String description) {
        this.description = description;
    }

    public Integer getParent_product_id() {
        return parent_product_id;
    }

    @OneToMany
    @JoinColumn(name = "product_id")
    public void setParent_product_id(Integer parent_product_id) {
        this.parent_product_id = parent_product_id;
    }


}

Image Entity

@Entity
public class Image {
    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    private Integer id;

    private String type;

    @ManyToOne
    private Product product_id;

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getType() {
        return type;
    }

    public void setType(String type) {
        this.type = type;
    }

    public Product getParent_product_id() {
        return product_id;
    }

    public void setProduct_id(Product product_id) {
        this.product_id = product_id;
    }


}

My ImageRepository

package model;

import org.springframework.data.repository.CrudRepository;

import java.util.List;

// This will be AUTO IMPLEMENTED by Spring into a Bean called userRepository
// CRUD refers Create, Read, Update, Delete

public interface ImageRepository extends CrudRepository<Image, Long> {

    List<Image> findByProduct_id(String id);
}

Thanks for the help guys!
