public Interface InitializingBean

Known Direct Implementers: org.springframework.beans.factory.config.AbstractFactoryBean, org.springframework.beans.factory.config.FieldRetrievingFactoryBean, org.springframework.beans.factory.config.MethodInvokingBean, org.springframework.beans.factory.config.PreferencesPlaceholderConfigurer, org.springframework.beans.factory.config.PropertiesFactoryBean, org.springframework.beans.factory.config.ServiceLocatorFactoryBean, org.springframework.beans.factory.config.YamlMapFactoryBean, org.springframework.beans.factory.config.YamlPropertiesFactoryBean, org.springframework.beans.factory.wiring.BeanConfigurerSupport

Interface to be implemented by beans that need to react once all their properties have been set by a BeanFactory: e.g. to perform custom initialization, or merely to check that all mandatory properties have been set.

An alternative to implementing InitializingBean is specifying a custom init method, for example in an XML bean definition. For a list of all bean lifecycle methods, see the BeanFactory javadocs.
