      default java.lang.Object postProcessAfterInitialization(java.lang.Object bean, java.lang.String beanName)
      Apply this BeanPostProcessor to the given new bean instance after any bean initialization callbacks (like InitializingBean's afterPropertiesSet or a custom init-method).
      default java.lang.Object postProcessBeforeInitialization(java.lang.Object bean, java.lang.String beanName)

        @Nullable
        default java.lang.Object postProcessBeforeInitialization(java.lang.Object bean,
                                                                           java.lang.String beanName)
                                                                    throws BeansException
        Apply this BeanPostProcessor to the given new bean instance before any bean initialization callbacks (like InitializingBean's afterPropertiesSet or a custom init-method). The bean will already be populated with property values. The returned bean instance may be a wrapper around the original.

        The default implementation returns the given bean as-is.

        Parameters:
        bean - the new bean instance
        beanName - the name of the bean
        Returns:
        the bean instance to use, either the original or a wrapped one; if null, no subsequent BeanPostProcessors will be invoked
        Throws:
        BeansException - in case of errors

      • postProcessAfterInitialization

        @Nullable
        default java.lang.Object postProcessAfterInitialization(java.lang.Object bean,
                                                                          java.lang.String beanName)
                                                                   throws BeansException
        Apply this BeanPostProcessor to the given new bean instance after any bean initialization callbacks (like InitializingBean's afterPropertiesSet or a custom init-method). The bean will already be populated with property values. The returned bean instance may be a wrapper around the original.

        In case of a FactoryBean, this callback will be invoked for both the FactoryBean instance and the objects created by the FactoryBean (as of Spring 2.0). The post-processor can decide whether to apply to either the FactoryBean or created objects or both through corresponding bean instanceof FactoryBean checks.

        This callback will also be invoked after a short-circuiting triggered by a InstantiationAwareBeanPostProcessor.postProcessBeforeInstantiation(java.lang.Class<?>, java.lang.String) method, in contrast to all other BeanPostProcessor callbacks.

        The default implementation returns the given bean as-is.

        Parameters:
        bean - the new bean instance
        beanName - the name of the bean
        Returns:
        the bean instance to use, either the original or a wrapped one; if null, no subsequent BeanPostProcessors will be invoked
        Throws:
        BeansException - in case of errors
