• The Bean container finds the definition of the Spring Bean in the configuration file.
  • The Bean container creates an instance of a Bean using the Java Reflection API.
  • If some attribute values are involved utilizeset()Method sets some property values.
  • If the Bean is implementedBeanNameAwareInterface, callsetBeanName()Method, the name of the Bean passed in.
  • If the Bean is implementedBeanClassLoaderAwareInterface, callsetBeanClassLoader()Method, passed inClassLoaderObject.
  • Similar to the above, if other implementations are implemented*.AwareInterface to invoke the corresponding method.
  • If there is a Spring container associated with loading the BeanBeanPostProcessorObject, executepostProcessBeforeInitialization()methods
  • If the Bean is implementedInitializingBeanInterface, executeafterPropertiesSet()Methods.
  • If the Bean definition in the configuration file contains the init-method attribute, the specified method is executed.
  • If there is a Spring container associated with loading the BeanBeanPostProcessorObject, executepostProcessAfterInitialization()methods
  • When it is time to destroy the Bean, if the Bean is implementedDisposableBeanInterface, executedestroy()Methods.
  • When it is time to destroy a Bean, execute the specified method if the Bean’s definition in the configuration file contains the destroy-method attribute.
