RabbitMqBeanPostProcessor implements BeanPostProcessor { @Override public Object postProcessAfterInitialization(Object bean, String beanName) throws BeansException { return bean; }  @Override Object postProcessBeforeInitialization(Object bean, String beanName); @Override Object postProcessAfterInitialization(Object bean, String beanName);  }### Answer:
@Test void testPostProcessAfterInitialization() { Object object = new Object(); Object result = rabbitMqBeanPostProcessor.postProcessAfterInitialization(object, "object"); assertThat(result).isNotNull(); assertThat(result).isSameAs(object); }
