Broadleaf: extending product entity failed

问题

Hi I Have extended the Broadleaf Product Entity and added a new attribute to that Entity and added the admin presentation annotation to display on the admin side

Here Is My Code to Extend the entity:

@AdminPresentationMergeOverrides({@AdminPresentationMergeOverride(name = "ExtendProductImpl.productWarranty", mergeEntries = {@AdminPresentationMergeEntry(propertyType = PropertyType.AdminPresentation.EXCLUDED, booleanOverrideValue=false)})})
public class ExtendProductImpl extends ProductImpl implements ExtendProduct {

@Column(name ="PRODUCT_WARRANTY")
@AdminPresentation(friendlyName = "product warrenty",
tab = TabName.General)

private String productWarranty;

 public String getProductWarranty() {

return productWarranty;

}



public void setProductWarranty(String productWarranty) {

this.productWarranty = productWarranty;

}}

Here Is my XML files in Core (ApplicationContextEntity.xml) :

Here is the another XML file (Persistant-core) :

You need to do 1 more thing and update the demo products to all be of your extended type. The problem is that if you are still relying on the demo data, Hibernate will still treat them as ProductImpl and not as ExtendProductImpl.

In your code snippet, you also do not have a @javax.persistence.Entity or @javax.persistence.Table annotations. Also, there is generally no need to create an interface for your custom domain object, it is optional. So assuming that it is actually this:

@Entity
@Table(name = "ext_product")
@AdminPresentationMergeOverrides({@AdminPresentationMergeOverride(name = "ExtendProductImpl.productWarranty", mergeEntries = {@AdminPresentationMergeEntry(propertyType = PropertyType.AdminPresentation.EXCLUDED, booleanOverrideValue=false)})})

public class ExtendProductImpl extends ProductImpl implements ExtendProduct {

You should then update the demo data to all be of ExtendProductImpl type by inserting data into the subclass:

INSERT INTO ext_product (PRODUCT_ID) (SELECT PRODUCT_ID FROM BLC_PRODUCT)

Finally, you might also want to ensure that whenever you create a product in the admin, it should always be of type ExtendProductImpl. To do this, use @AdminPresentationClass:

@Entity
@Table(name = "ext_product")
@AdminPresentationClass(ceilingDisplayEntity = "com.mycompany.ExtendProductImpl")
@AdminPresentationMergeOverrides({@AdminPresentationMergeOverride(name = "ExtendProductImpl.productWarranty", mergeEntries = {@AdminPresentationMergeEntry(propertyType = PropertyType.AdminPresentation.EXCLUDED, booleanOverrideValue=false)})})
public class ExtendProductImpl extends ProductImpl implements ExtendProduct {
