接口 AssociationIntegrityAssuranceFilter<P extends Props>

类型参数:

P - Filtered type, it is often a type decorated by @MappedSuperclass.

所有超级接口:

Filter<P>

public interface AssociationIntegrityAssuranceFilter<P extends Props>
extends Filter<P>

This interface should only be used by Java, kotlin developers can use `KAssociationIntegrityAssuranceFilter<E>`

The user's commitment to ensure that the filtered fields of two associated objects are the same.

Let's look at an example with the following defined entities:

  @MappedSupperclass
  public interface TenantAware {
      String tenant()
  }
 

  @Entity
  public interface Department extends TenantAware {
      ...
  }
 

  @Entity
  public interface Employee extends TenantAware {
      @ManyToOne
      Department department(); // Nonnull many-to-one association
      ...
  }
 

Here both Department and Employee support multi-tenancy, with a defined filter:

  @Entity
  public interface TenantAwareFilter extends AssociationIntegrityAssuranceFilter<TenantAwareProps> {
      @Override
      public void filter(FilterArgs<P> args) {
          ...
      }
  }
 

This filter implements the `AssociationIntegrityAssuranceFilter` interface. This indicates the user's commitment that associated `Department` and `Employee` objects must belong to the same tenant, `Department` and `Employee` objects belonging to different tenants will never be associated. If the many-to-one association `Employee.department` could not be null without the filter, then with this filter applied to both `Department` and `Employee` sides, this association also cannot be null.
