I am getting "uninitialized proxy passed to persist()" during persist of an object. What does this mean?

org.hibernate.PersistentObjectException: uninitialized proxy passed to persist()

The entity has one many to many relationship, as

@ManyToOne @JoinColumn(name="brand_id") private Brand brand;

and one OneToOne relationship as,

    @OneToOne(cascade=CascadeType.ALL , fetch=FetchType.LAZY)
    @JoinColumn(name="addressToSendAC_FK")
    private BrandAddress addressToSendAC;

Are these causing the error ?

Edit:

stacktrace added.

Since you didn't provide much details it's hard to tell what happened for sure, but I will guess that you got proxy but never hit the database to get object information before trying to persist object. Relevant piece from Hibernate documentation:

If the class is mapped with a proxy, load() just returns an uninitialized proxy 
and does not actually hit the database until you invoke a method of the proxy.

http://docs.jboss.org/hibernate/core/3.3/reference/en/html/objectstate.html#objectstate-loading

TLDR Make sure you correctly initiate Hibernate session / use @Transactional annotation.

Background: Stack: JPA/Hibernate, Spring Boot 2.7.6

With an introduction of a method in my service that had to persist aggregate entity with other referenced entities I got the same exception:

uninitialized proxy passed to persist()

Following TTD, this exact invocation worked without any issue in integration test. Finally found out that test method was automatically wrapped in a transaction, where the @Transaction annotation was missing in my service method as before there were no DB actions present.

After adding springframework @Transactional annotation on the service method persistence works as expected.
