SpringBoot基礎教程(十二)——與EventListener的結合

sub/pub模式在軟件設計中是非常常見的，他可以很優雅的幫我們解耦合，很多優秀的軟件中都能看到他的影子，不如redis,zk,rxjava等，spring的內部也有很多的應用，今天我們就說一下事件的監聽。

首先我們要知道事件的種類是多種多樣的，我們的事件監聽器（EventListener）關注什么樣的事件呢？根據這個思路我們看下本次課程我們定義的

package com.shuqi.listener;

import lombok.extern.slf4j.Slf4j;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationListener;
import org.springframework.context.event.ContextRefreshedEvent;

import java.util.stream.Stream;

@Slf4j
public class TestListener implements ApplicationListener<ContextRefreshedEvent> {

    @Override
    public void onApplicationEvent(ContextRefreshedEvent contextRefreshedEvent) {
        ApplicationContext applicationContext = contextRefreshedEvent.getApplicationContext();
        Stream.of(applicationContext.getBeanNamesForType(Object.class)).forEach(log::info);
    }
}

實例中的事件監聽器關注的是ContextRefreshedEvent的事件，也就是說當容器refresh結束的時候會發出這個事件，我們的監聽器就能監聽到，所做的操作就是打印容器中的Bean的名稱。
那么我們事件是有了，我們下一步就不要將這個事件監聽器讓Spring boot知道，所以就是一個注冊。

package com.shuqi;

import com.shuqi.listener.TestListener;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

import java.text.SimpleDateFormat;
import java.util.Date;

@SpringBootApplication
public class ApplicationMain {

    public static void main(String[] args) {
        SpringApplication springApplication=new SpringApplication(ApplicationMain.class);
        springApplication.addListeners(new TestListener());
        springApplication.run(args);

        System.out.println(new SimpleDateFormat("[yyyy-MM-dd HH:mm:ss]").format(new Date()) + " server started!");
    }
}

這樣我們一個事件監聽器就完成了。
啟動看看效果
