List of preInstantiateSingletons() Examples

Examples of preInstantiateSingletons()

org.springframework.beans.factory.config.ConfigurableListableBeanFactory.preInstantiateSingletons()
Ensure that all non-lazy-init singletons are instantiated, also considering {@link org.springframework.beans.factory.FactoryBean FactoryBeans}. Typically invoked at the end of factory setup, if desired. @throws BeansException if one of the singleton beans could not be created.Note: This may have left the factory with some beans already initialized! Call {@link #destroySingletons()} for full cleanup in this case. @see #destroySingletons()
