JPA OneToMany using FetchType.EAGER

Scenario: Want to insert multiple address to basket header with a unique basketId.

BasketHeader.java @OneToMany(fetch = FetchType.EAGER, cascade = CascadeType.ALL) @JoinColumn(name = "basketId", nullable = false) public Set getBasketBillTos() { return basketBillTos; }

By specifying @JoinColumn basketId is set as the foreign key column name for the relationship. Otherwise a default name will be given for the foreign key column. If you are mapping to an existing database schema you will typically require setting the @JoinColumn, otherwise the defaults are probably fine. Implementation on action

Set basketBillToSet = new HashSet(); basketBillToSet.add(basketBillTo); basketHeader.setBasketBillTos(basketBillToSet);
