Hibernate: More than one row with the given identifier was found error

Question

I\'m using spring 4.0.5 and hibernate 4.3.5; I\'m facing an error with hibernate and I can\'t figure where I\'m wrong (because I\'m sure I\'m wrong). I have a table related

Answer 1

If you have @OneToOne mapping in your class then update the fetch type to LAZY. Because by default fetch type for OneToOne is EAGER so when we fetch object of main class (WebTree) class, it will fetch the object for OneToOne mapped class so when hibernate map the object it will throw the exception. In Short if you have OneToOne Mapping then replace it with @OneToOne(fetch = FetchType.LAZY).
