Я получаю LazyInitializationException при использовании методов createQuery () , load () или get () . Конфигурация основана на аннотациях. < /P>
Это исключение, которое я получаю: < /p>
Method threw 'org.hibernate.LazyInitializationException' exception. Cannot evaluate lt.package.to.Setting_$$_jvstfff_0.toString()
