I am new to Hibernate and trying to get a OneToOne annotation to work. I've looked at lots of examples, other threads, and the documentation and can not figure out what I am doing wrong here. As far as I can tell mine is identical to some of the example's I've seen.
Table: loan (Owner)
Code:
id int primary key
(Other columns ommitted)
Table: loanPaymentInfo
Code:
loanId int primary key references loan(id)
Code:
@Entity
public class Loan{
@Id
private Long id;
@OneToOne(cascade = CascadeType.ALL, fetch=FetchType.LAZY, mappedBy="loan")
@JoinColumn(name="id")
private LoanPaymentInfo paymentInfo;
//paymentInfo getter (no setter)
}
@Entity LoanPaymentInfo{
@Id
@GeneratedValue(generator="foreign")
@GenericGenerator(name="foreign", strategy = "foreign", parameters={
@Parameter(name="property", value="loan")
})
private Long loanId;
@OneToOne(fetch=FetchType.LAZY)
@PrimaryKeyJoinColumn
private Loan loan;
//loan getter (no setter)
}
When I create a loan and set some properties on loan and loanPaymentInfo, I get the following exception:
Code:
