如何编写函数在Spring Application事件上过滤事件

import org.springframework.context.ApplicationListener;
import org.springframework.stereotype.Component;

@Component
public class EventFilter implements ApplicationListener<CustomEvent> {

    @Override
    public void onApplicationEvent(CustomEvent event) {
        // 在这里编写过滤逻辑
        // 可以根据事件的属性进行过滤判断
        // 如果符合条件，则进行相应处理
    }
}

public class CustomEvent {

    private String eventType;

    // 其他属性...

    public CustomEvent(String eventType) {
        this.eventType = eventType;
    }

    public String getEventType() {
        return eventType;
    }

    // 其他属性的getter和setter方法...
}

import org.springframework.context.ApplicationEventPublisher;
import org.springframework.stereotype.Component;

@Component
public class EventPublisher {

    private final ApplicationEventPublisher eventPublisher;

    public EventPublisher(ApplicationEventPublisher eventPublisher) {
        this.eventPublisher = eventPublisher;
    }

    public void publishEvent(String eventType) {
        CustomEvent event = new CustomEvent(eventType);
        eventPublisher.publishEvent(event);
    }
}
