I need to transform the jsonObject before the object binding. So is there a more efficient way to achieve the binding from a JsonObject? (Note I want to implement with Java EE 8 standards,

In Customer class: @OneToMany(mappedBy = "customer", orphanRemoval = true) @JsonIgnore private List<Item> items; In Item class: @ManyToOne(fetch = FetchType.LAZY) @JoinColumn(name = "CUSTOMER_ID"
