I have a JPA
code with OneToMany
relationship. A Customer
has a list of Item
to check out. However, the code continue to generate StackOverflowError
.
Once, I had resolved this one by applying @JsonIgnore
while fetching the List<Item>
from Customer entity. But even that does not seem to work anymore.
In Customer
class:
@OneToMany(mappedBy = "customer", orphanRemoval = true)
@JsonIgnore
private List<Item> items;
In Item
class:
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "CUSTOMER_ID", nullable = false)
private Customer customer;
And CustomerRest
class:
@Path("customers")
public class CustomerRest {
@Inject
NewSessionBean newSessionBean;
@GET
@Produces(MediaType.APPLICATION_JSON)
public List<Customer> getAllCustomers() {
return newSessionBean.getCustomers();
}
}
Method newSessionBean.getCustomers()
:
public List<Customer> getCustomers(){
TypedQuery<Customer> q= em.createQuery("select c from Customer c", Customer.class);
return q.getResultList();
}
I expect a nicely formatted JSON message but there is no sign of this. All I get is the java.lang.StackOverflowError
on the browser and the Server log generates the following:
