I am converting from Hibernate hbm files to JPA/Hibernate Annotations
I have the following

<many-to-one name="serviceCode" class="crown.core.types.FacilityServicesType" lazy="false" >
<column name="SERVICE_TYPE" unique-key="UNIQUE_KEY_SVCS">
<comment>Facility service code</comment>
</column>
</many-to-one>

I have problem to define unique-key in annotations.

I did the following:

@ManyToOne(fetch=FetchType.EAGER)
@JoinColumn(name="SERVICE_TYPE")
private FacilityServicesType serviceCode;

How should I define unique-key here?

Thanks for help

The <column> element roughly equates to the @Column annotation, so have a look there:
