spring event 事件

事件流程

1发布事件 ApplicationEventPublisherAware

2监控事件 ApplicationListener

3.生成事件 applicationEvent

发布事件

package com.example.demo.qin;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.ApplicationEventPublisher;
import org.springframework.context.ApplicationEventPublisherAware;
import org.springframework.stereotype.Component;

/**
 * @program: springboot_test
 * @description: 事件发布
 * @author: Mr.qin
 * @create: 2018-12-19 06:14
 **/
@Component
public class EventPublish implements ApplicationEventPublisherAware {
    @Autowired
    private  ApplicationEventPublisher applicationEventPublisher;

    public void publish(EventTest event){
        applicationEventPublisher.publishEvent(event);
    }

    @Override
    public void setApplicationEventPublisher(ApplicationEventPublisher applicationEventPublisher) {
        this.applicationEventPublisher=applicationEventPublisher;
    }
}

监控事件

package com.example.demo.qin;

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

/**
 * @program: springboot_test
 * @description: 事件监听
 * @author: Mr.qin
 * @create: 2018-12-19 05:38
 **/
@Component
public class EventRelease implements ApplicationListener<EventTest> {
    @Override
    public void onApplicationEvent(EventTest event) {
        System.out.println("更新失败回，删除插入信息"+event.getEventStr()+event.getSource());
    }
}

　　

 生成事件

package com.example.demo.qin;

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

/**
 * @program: springboot_test
 * @description: 事件监听
 * @author: Mr.qin
 * @create: 2018-12-19 05:38
 **/
@Component
public class EventRelease implements ApplicationListener<EventTest> {
    @Override
    public void onApplicationEvent(EventTest event) {
        System.out.println("更新失败回，删除插入信息"+event.getEventStr()+event.getSource());
    }
}
