lazy aroundとは 意味・読み方・使い方

Note. At the time of writing, the Hibernate JPA persistence provider has some known issues that can cause problems in web applications such as JavaServer Faces applications.While not specific to NetBeans, these issues can be worked around by choosingeager as the association fetch value and java.util.Set as the collection type in the Mapping Options pane.If you use the Hibernate JPA persistence provider and choose default or lazy as the association fetch value in the Mapping Options pane,an org.hibernate.LazyInitializationException exception can occur at runtime.If you choose an association fetch value of eager and you do not also choose java.util.Set as the collection type,an org.hibernate.HibernateException can occur (with the message"cannot simultaneously fetch multiple bags") at runtime.These issues pertain to the Hibernate JPA persistence provider and not to the defaultpersistence provider.例文帳に追加
