Type: Interface | 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/ApplicationEventInterceptor.java

Overview

An interface used to intercept ApplicationEvent application events allowing for pre-processing, post-processing, or even prevention of event propagation through the ApplicationEventInterceptorChain interceptor chain.

Interceptors can be used to implement cross-cutting concerns such as logging, security checks, or performance monitoring around the application event handling process.

{@code
public class LoggingInterceptor implements ApplicationEventInterceptor {

### Declaration

public interface ApplicationEventInterceptor extends Ordered
