io microsphere spring context event EventPublishingBeanInitializer

EventPublishingBeanInitializer

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/EventPublishingBeanInitializer.java

Overview

An ApplicationContextInitializer that registers processors to publish Spring bean lifecycle events during context initialization.

This initializer executes with the highest priority to guarantee that bean event publishing capabilities are established before other components are processed. It automatically registers an EventPublishingBeanBeforeProcessor as a org.springframework.beans.factory.config.BeanFactoryPostProcessor.

Configuration

The initializer is disabled by default. Enable it via the application configuration:

# application.properties
microsphere.spring.event-publishing-bean.enabled=true

Example

After enabling, you can listen to bean events by implementing a BeanListener:

@Component
public class MyBeanListener implements BeanListener {
    @Override
    public void onBeanBeforeInitialization(String beanName, Class<?> beanType) {
        // Custom logic before bean initialization
    }
}

Declaration

public class EventPublishingBeanInitializer extends ConfigurableApplicationContextInitializer implements PriorityOrdered
