io microsphere spring context event LoggingBeanFactoryListener

LoggingBeanFactoryListener

Type: Class | Module: microsphere-spring-context | Package: io.microsphere.spring.context.event | Since: 1.0.0

Source: microsphere-spring-context/src/main/java/io/microsphere/spring/context/event/LoggingBeanFactoryListener.java

Overview

A BeanFactoryListener implementation that provides logging capabilities for Spring BeanFactory events.

This class logs the key lifecycle events of a Spring BeanFactory, such as when a BeanDefinitionRegistry is ready, when a ConfigurableListableBeanFactory is initialized, and when the BeanFactory configuration is frozen. The logging is done using the Logger interface provided by the MicroSphere logging framework.

Example Usage

`// Register the LoggingBeanFactoryListener with the Spring context
context.addBeanFactoryListener(new LoggingBeanFactoryListener());
`

When the BeanFactory events are triggered, log messages will be generated similar to the following:

INFO  onBeanDefinitionRegistryReady - BeanDefinitionRegistry : org.springframework.beans.factory.support.DefaultListableBeanFactory@1f9e655
INFO  onBeanFactoryReady - BeanFactory : org.springframework.beans.factory.support.DefaultListableBeanFactory@1f9e655
INFO  onBeanFactoryConfigurationFrozen - BeanFactory : org.springframework.beans.factory.support.DefaultListableBeanFactory@1f9e655

These logs provide visibility into the internal state of the Spring container during startup and can be useful for debugging and monitoring purposes.

Declaration

public class LoggingBeanFactoryListener implements BeanFactoryListener
