Hi,<\/p>\n

Some times when we access domain objects of collections in one to many or many to many\u00a0relationships,\u00a0we get Hibernate class wrapped with javassist, basically hibernate wraps all loaded objects with javassist\u00a0after loading(lazy loading case)\u00a0them .<\/p>\n

So if \u00a0we call \u00a0class.name<\/code> on the members of collections in one to many or many to many relationships <\/span>we would get class names something like com.test.classname_javassist_59<\/code>.<\/p>\n

So to solve this issue, hibernate provides a\u00a0HibernateProxyHelper<\/strong><\/code> class that has a static method to return the class without the wrapped javassist .<\/p>\n

[java]HibernateProxyHelper.getClassWithoutInitializingProxy(object)[\/java]\r\n\r\n <\/code><\/pre>\n
This method returns the class \u00a0without the \u00a0javassist proxy of hibernate class. If the\u00a0wrappedClassObject<\/code> is not proxied by javassist the original class will be returned. \ud83d\ude42<\/p>\n
