8.12.3 @AttributeOverride

(1) Description

This annotation overrides the following mapping information:

• Properties or fields specified by @Basic (applied by default)

• Properties or fields applied by default

• Properties or fields specified by @Id

To override the settings of @Column defined in the mapped superclass and embedded class, apply the field or property of the entity class and embedded class in which the mapped superclass is inherited.

If @AttributeOverride is not specified, the column is mapped with the original mapping before override.

If @AttributeOverride is defined in the entity class of a unit that does not have an inheritance relationship, the operation is performed; however, the operation cannot be guaranteed.

The applicable targets are class, method, and field.
