I'm trying to have one to many connection between two classes but im getting this error org.hibernate.AnnotationException: Illegal attempt to map a non collection as a @OneToMany
.
here is my code,
Job.java
@OneToMany
@JoinColumn(name = "id", referencedColumnName = "id", insertable = false, updatable = false)
private Set<JobCostSplit> jobCostSplit;
JobCostSplit.java
@Column(name = "job_id")
private Long jobId;
@JsonIgnore
@OneToMany
@JoinColumn(name = "job_id", referencedColumnName = "id", insertable = false, updatable = false)
private Job job;
You annotate your Job
with @OneToMany
. Means you will have one attribute on Job
and more on JobCostSplit
.
So if you want to have one Job
and more JobCostSplit
you have to set it like this:
@ManyToOne
@JoinColumn(name = "job_id", referencedColumnName = "id", insertable = false, updatable = false)
private Job job;
