Lifecycle callbacksInitializingBean and DisposableBean interfaces.The container callsafterPropertiesSet() for the former and destroy() for the latter to allow the bean to performcertain actions upon initialization and destruction of your beans.prototypeと一緒に使わないでください

Destruction callbacks
...is exactly the same as...
Default initialization and destroy methods
The presence of the default-init-method attribute on the top-level element attributecauses the Spring IoC container to recognize a method called init on beans as the initialization methodcallback.
Where existing bean classes already have callback methods that are named at variance with theconvention, you can override the default by specifying (in XML, that is) the method name using theinit-method and destroy-method attributes of the itself.
