How to use @Embedded object with @AttributeOverride in Spring Hibernate Framework

When Embedding same embeddable object multitimes with the entity will get ambigious to select the name of the embeddable class members. To specify different name for each embedded members in the current entity uses @AttributeOverrides and @AttributeOverride annotations.

Example
@Embedded
private Address homeAddress;

@Embedded
@AttributeOverrides({
@AttributeOverride(name="city",column=@Column(name="OFFICE_CITY_NAME")),
@AttributeOverride(name="state",column=@Column(name="OFFICE_STATE_NAME"))
})
private Address officeAddress;

Output

Hibernate: drop table if exists STUDENT_INFO
Hibernate: create table STUDENT_INFO (STUDENT_ID integer not null auto_increment, STUDENT_NAME varchar(255), CITY_NAME varchar(255), STATE_NAME varchar(255), OFFICE_CITY_NAME varchar(255), OFFICE_STATE_NAME varchar(255), primary key (STUDENT_ID)) ENGINE=InnoDB

Called for; Student:0
Hibernate: insert into STUDENT_INFO (STUDENT_NAME, CITY_NAME, STATE_NAME, OFFICE_CITY_NAME, OFFICE_STATE_NAME) values (?, ?, ?, ?, ?)
