Hi everyone,

Foremost my setup:
- I have 2 Classes - Person(entity) and Address(component), in which a Person object can have 1 or more Address objects
- Person-to-Address association within Person class
@ElementCollection(fetch = FetchType.EAGER)
@JoinTable(name = "T_Address", joinColumns = @JoinColumn(name = "ORDER_ID"))
public List<Address> getAddresses() {
return addresses;
}
- Address-to-Person association within Address class not needed since I do not need any address-to-person reference

My current Situation:
Whenever I modify an address field or add/delete an address object within the address List in a person object, Hibernate seems to first delete all address objects associated with this person, and afterwards it has them inserted again.

In the Code below I only modified the street of an address object; Hibernate deleted all Adress objects and subsequently inserted all 3 Address objects into Address table again:

Hibernate: delete from T_ADDRESS where PERSON_ID=?
Hibernate: insert into T_ADDRESS (PERSON_ID, CREATED, STREET, ZIP, COUNTRY) values (?, ?, ?, ?, ?)
Hibernate: insert into T_ADDRESS (PERSON_ID, CREATED, STREET, ZIP, COUNTRY) values (?, ?, ?, ?, ?)
Hibernate: insert into T_ADDRESS (PERSON_ID, CREATED, STREET, ZIP, COUNTRY) values (?, ?, ?, ?, ?)



My Question:
Is there any possibility to make Hibernate only delete/modify/add the affected address objectwithin the address list of the person object? For I hope the solution will improve the performance of my written program tremendously.

Thank you for your time and help. I really appreciate it!
