@Target(value={TYPE,METHOD,FIELD})
@Retention(value=RUNTIME)
public @interface AttributeOverride
The AttributeOverride annotation is used to
override the mapping of a Basic (whether explicit or
default) property or field or Id property or field.
The AttributeOverride annotation may be
applied to an entity that extends a mapped superclass or to
an embedded field or property to override a basic mapping
defined by the mapped superclass or embeddable class. If the
AttributeOverride annotation is not specified,
the column is mapped the same as in the original mapping.
Example: @MappedSuperclass public class Employee { @Id protected Integer id; @Version protected Integer version; protected String address; public Integer getId() { ... } public void setId(Integer id) { ... } public String getAddress() { ... } public void setAddress(String address) { ... } } @Entity @AttributeOverride(name="address", column=@Column(name="ADDR")) public class PartTimeEmployee extends Employee { // address field mapping overridden to ADDR protected Float wage(); public Float getHourlyWage() { ... } public void setHourlyWage(Float wage) { ... } }
